Image Links

| No TrackBacks
Normally when you think of links, you think of text that has been coded to take you to a different website. This text is not only boring, but also fails to provide a visualization or explanation of what the linked website contains.

An alternative to text links are image links. Image links are images that have been turned into a link. This can be especially useful in providing an image that is linked to a website explaining its significance, or when providing an image of, for example, a formula whose link takes you to an interactive web page that allows you to solve for the formula. In short the possibilities are numerous and can adapt to any context, whether it is for instructional or personal use. Examples of text vs. image links is provided below:

Text Link:

Student Technology Program

Image Link:

Picture 2.png









This entry will explain how to make any image that you choose into a link. The process is relatively simple, with two methods to creating an image link.

The first method involves creating your own image to be turned into a link. To do so you would follow the simple format:

1. First you make or choose your image

2. Then you upload your image to a server

3. And finally, you input the html code to make an image link

The second method involves using an image that is already available online. To do so you would follow the simple format:

1. Copy the image URL

2. Paste the image URL into the code for an image link.

The following is a description of the First Method:

There are two ways that you can choose your image. The first is to search for your image in a search engine (such as Google, Yahoo, or MSN) and then saving it to your computer as an image file (JPEG, etc.). *

The second option that you have is to create your own image. This can be done by uploading your own picture from a camera, or taking a screenshot of the image that you would like to turn into a link. Please refer to my colleague's, Dobromir Trifonov's, post regarding screenshots:

Take Screenshots....

Now that you have your image selected, you will have to upload it to a server. You can use any server, although for this entry I will assume that you are working with Moodle and will therefore discuss uploading an image file to its server.

First, you must access your course in Moodle and click on the Files link under the Administration box.

files.jpg

Once there you can either make a folder (making a folder will be necessary if you want to have an organized collection of files on Moodle) or simply upload a file.

upload file copy.jpg

Once you have uploaded your file, you will be able to see a link to see your image. Right click on this link and select the option Copy Link Address. This is your image source.

The HTML code for creating an image link is as follows:

<a href="Website Link" border="0"><img alt="" src="Image Source" title="Title to Appear when Mouse Hovers over image" width="width pixels" height="height pixels" /></a>

Once again, you will only be manipulating the following segments of code Website Link, Image Source, Title to Appear when Mouse Hovers over Image, and width/height pixels. The Website Link will be the URL of the website that you are linking to. Your final code should look similar to this:

<a href="http://blogs.trincoll.edu/sta/" border="0">

<img alt="" src="http://b27.cc.trincoll.edu/weblogs/sta/Image Links/Picture%202.png" width="400" height="87" />

</a>

Notice how the italicized portion of the text is simply your image's image source.

Now all you need to do is copy and paste this code wherever you want your image link to appear.

The second method, using an image already online, is very simple. First you locate your image, then you right click it, select Copy Link Address and then paste the link address (your image source) into the corresponding location of the HTML code for image links.

If you have any questions or concerns regarding this, or any, STA Blog Post, please feel free to call the STA Office at extension x2589 or come and speak with one of our Student Technology Assistants during our normal business hours. Thank you.


Creating a slideshow with voiceover is a fairly straightforward task with a Mac. All you need are the pre-installed software iMovie and iPhoto as well as a microphone.

First of all import your photos in Iphoto. It is suggested that you import all the photos in one batch and give it an easy to remember name.

Open iPhoto.
Go to File --> Import to Library-->Select photos and import them
You can edit any of the photos if they need a bit of touching up. It is suggested that you pay special emphasis to the orientation of the pictures. Don't forget to save any of the changes you make!

Now open iMovie.
Create a new project by going to File--> Create a New Project

Now click on the small camera icon on the right hand side of the screen. iPhoto will open up and you can search for any photos imported to iMovie. The photos you recently uploaded will be present in the Last Import folder.

Slideshow1.jpg

Now select one photo and then drag and drop it into the Project Window. The Project Window looks like a series of empty paper cutouts.

Once your images are in the Project Window, you can double click on any image and edit minor details like the length of time the image will be displayed.

 Slideshow2.png

When you click on any image thumbnail in the Project Window, follow this up by clicking on the Crop icon, another window should now display an enlarged version of the photo.

Minor Editing is allowed by iMovie. They are namely

Fit:
This fits the entire photo as into the slideshow, no camera panning.

Crop:
Allows you to crop the photo

Ken Burns:

Slideshow6.png
This option allows you to pan over the image. If your image is over the maximum resolution of the video, you can perform a "Ken Burns" effect. This essentially pans the camera across the picture. The Green Rectangle shows the starting view and the red rectangle shows the view the image ends with. The yellow direction arrow shows you the direction across which the camera will pan during the slide show. You can preview effects by hitting on the play button on the top right corner.

Rotate:
You can easily rotate images with the rotate icons on the top of the screen

Once you are satisfied with the photo layout. You can begin the voice over process by hitting the microphone icon.

You can also select the audio input method if you have an external microphone with you. If not, iMovie automatically selects the built in microphone.

Once you are done. Just click on the Edit Project tab and this will take you to the Project library.
Slideshow7.jpg
Now just right click on the project, hit Export Movie...--> Choose settings and your movie will be created.




Scanning devices in the library

| No TrackBacks

As major assignments come up, students and professors often have to utilize the functions of scanning devices. This blog will give you insights about the availability of different scanners in the library, as well as the main functions that each of them serves.

 Our preferred scanning station is located in the MDS room (Library, Rm 135).

The station has two scanning devices, which allow you to scan letter-size documents, photography films, and slides.

1) The HP scanner in the room has several convenient functions:

  • an automatic feeder dock where you can place at a time up to 30 standard letter-size sheets of paper that will be scanned without your manual intervention. This function saves a lot of time and the hassle of placing/removing each sheet by hand. * To use the automatic feeder, all you have to do is put the sheets in the feeder and initiate scanning. You will be told that the automatic feeder is turned on and that the scanner will use it. When you place the sheets in the feeder, please make sure that the sheets are not stuck to each other, stapled together or held together by other means.
  • an accessory for film strip scanning. Place your developed film strip in the accessory and position the accessory on the scanning screen. The scanner is not going to create a photograph out of the developed film. It will simply scan the film and save it as a negative image.

The scanner works with HP ProScan software. The software is easy to navigate with and offers a variety of options. You can save scans in different file formats: image, text, pdf; you can also forward the scans to a software solution, such as Photoshop, Adobe Reader, Microsoft Word, where you could further edit them.

2) The Nikon slide scanner. It is very useful when you need high-resolution copies of the slide images. The device can scan one slide at a time, at an average of 20 seconds per slide. Bear in mind that if you need to scan many slides, the process might take a considerable amount of time. *If you would like to learn some quick tips about slide/film scanning click HERE


Scanning station next to Blume Computer Lab

If you need to scan just a few pages, we would encourage you to use the scanners by the Blume Lab on Library Level 1. The two scanners are located in the carrels, in the common area, right in front of the Blume lab.

Before you start using them, please make sure that they are turned on. Once the power is on, you can make your scans with HP Image Zone, Adobe Acrobat Pro, Photoshop and other software products.

Scanning station on Library, Level A
If you would like to scan larger in size or volume objects, we would advise you on using the touchscreen book scanner on Library level A. The scanner is located in the common area, close to the Dell computers.

It is very easy to navigate with. Before you start scanning, the software will go through several simple steps. It will ask you where you would like to have the files sent to (a USB drive, printer, or e-mail); the file format (pdf, image, etc.); the color mode & resolution. You will then proceed to scan.

Scanning stations in FITC & STA (available to faculty only)
There are two additional scanners in the Library available only to faculty. One of the scanners is located in FITC (Library, Level A), and the other one is in the STA office (Library, Rm 134a).

In case you need assistance with any of the scanners or the scanning software, the STAs will be glad to assist you. Please contact us for any additional help.

Word Clouds

| No TrackBacks

Word Clouds are an efficient tool that can help you visualize the content within a text. Word clouds are also sometimes called tag clouds.This entry will outline the major resources available to generate a visually aesthetic and informative word cloud.

By visualizing the word content of a text, you can quickly assess its content and what it refers to. It is in essence a quick and easy way to scan the document that you would like to read. For example, if a word cloud were to be generated based on my previous entry, Assignment Reviews-Electronically!, the world cloud would quickly provide a quick overview of the topics that I am talking about:

Capture.JPG

As you can see, the biggest words correspond to the most common words found in the text: Track, Review, Edit, Changes, Word.

There are a number of different resources that you could use to generate your word cloud. Below is a list of the most useful word cloud generators:

Tagxedo: http://www.tagxedo.com/app.html

Tag Crowd: http://tagcrowd.com

Wordle: http://www.wordle.net/

Each word cloud generator offers its unique set of tools. Here is a comparison of the most useful features of all three word cloud generators:

comparisons.jpg

Below are three word clouds from each world cloud generator that highlight their distinguishing features.

Tagxedo:

Wordle

wordle.png

I encourage you to visit each resource to utilize their word cloud generators. The more familiar you get with each program, the more applications you will be able to perform. For example, if you wanted to create a visual representation of the world's population, you could create a word cloud (which at this point would become a data cloud) with a total of 100 words. You could then copy and paste a country's name into the raw text generator however many times reflects their percentage of the world population. In other words, if the population of China is about forty percent of the world population, then you would paste in the word China forty times. This process would continue on for as many countries as you would like. Below is an example of a data cloud representing world population by countries comprising more than 0.5% of the world population.

WORLD POP.jpg

If you have any questions or concerns regarding this entry, including how to use the specific features of each word cloud generator, please feel free to call the STA Office at extension x2589 or come and speak with one of our Student Technology Assistants during our normal business hours. Thank you.

The scratch disk is a folder in your hard drive where final cut express saves all your projects, audio/video files as well as renders files. The scratch disk is where all media files used and rendered by Final Cut is saved by default. Final Cut is preset so that the scratch disk is located on the same drive final cut is installed in. Raw video files are a huge resource hog, and can consume many gigs of space as well as significant processor and RAM use during video rendering and compressing. Hence, it is recommended that you either install Final Cut in a disk drive separate from the one the Operating System is located in (so that the Scratch disk is automatically created on the same drive) or else you manually move the scratch disk to another location.

Most video enthusiasts prefer to use external memory storage for video editing purposes. The benefits of doing this are listed below.

System performace is faster if an external hard drive is used
It is easier to transport and edit files on different computer with an external hard drive
External hard drives allow you to exponentially increase the amount of space you have available (Hard drives with more than 1 Tb memory are the norm these days).  

The procedure to setting up an external hard drive as a scratch disk is as follows:

  • Insert your external hard drive accordingly (Firewire or USB)
  • Open Final Cut Express
  • System Settings-->Locate and add External Hard Drive -->Set

Scratchdisk.jpg


  • Video Capture, Audio Capture, Video Render, and Audio Render: Check these boxes to specify the types of files to be stored on each disk. Specify more than one disk for increased storage space. When the current disk runs out of space, Final Cut Express automatically switches to the next specified disk for storing capture files or to the disk with the most space available for storing render files.
  • Clear: Click to remove a disk from the list of available disks.
  • Set: Click to choose a disk or a folder on a hard disk. You can specify up to 12 disks.
  • Waveform Cache: Click the Set button to specify a folder or disk to store waveform cache files (graphical representations of audio signals). The default location is the Final Cut Express Documents folder on your scratch disk.
  • Thumbnail Cache: Click the Set button to specify a folder or disk to store thumbnail cache files. The default location is the Final Cut Express Documents folder on your scratch disk. You specify the size of this cache on the Memory & Cache tab.
Scratchdisk3.jpg
  • Autosave Vault: Click the Set button to specify a folder or disk to store FCE's automatic backup copies of your project files. The default location is the Final Cut Express Documents folder on your scratch disk. For more information on the Autosave Vault, see Chapter 4, "Projects, Sequences, and Clips."
  • Minimum Allowable Free Space on Scratch Disks: Enter a limit value. When disk space falls below this minimum, a disk will no longer be used as a scratch disk, and files will be stored on the next disk in the list.
  • Limit Capture/Export File Segment Size To: Enter a limit value. The default value is 2 GB. Final Cut Express allows the capture and export of single files larger than 2 GB, but if you plan to move your files to another system that has a file size limitation, or if you share media files over a network, you should enable this option. Files that are larger than your specified limit will be spanned (written as separate, but linked, files).
  • Limit Capture Now To: Enter a limit value. The default limit is 30 minutes



Final Cut Express basics

| No TrackBacks
Final Cut is a comprehensive audio and video editing software developed by Apple that is widely used to make and edit videos. One of the core features of Final Cut is the ability to make non-linear edits. This essentially means you have the ability to jump to different parts of the video and make multiple edits simultaneously. It is a break from linear editing process that was much more rigid in structure and provided very little flexibility. An added consideration is the fact that Final Cut only works on Macs and depending on the version of Final Cut, some are optimized for use only with the latest intel processors.

Final Cut is sold in two different forms

Final Cut1.jpg

Final Cut Studio ($999)
This is the full version of Final Cut and is mostly used for high end professional film and video editing. Media Composer and Final Cut Studio are the primary software tools used to edit and create professional movies and music videos. Almost 50% of all major video production (movies, documentaries and music videos) is done by Final Cut Studio.


Final Cut Express ($199)
And finally Express is the consumer version of Final Cut so to speak. It is practically the bare bones version of Final Cut that performs the basic functions of Final Cut with a few extras. It retains multiple video tracks, viewer and canvas viewer format and most customizing tools from cropping images to adding special effects. In short, it is a very capable software that can fulfill most general consumer needs for basic video projects. The major omittances are related to specific format issues that are mostly only needed for major film production and complex editing.

The limitations of Final Cut Express are highlighted below:

Limited Video Support
Final Cut Express will only support HDV video. Final Cut Pro on the other hand will support all HD formats. If you are shooting on a HDV camera at 1080i or 720p, MiniDV, DVCAM, or DVCPRO camcorder then you will be supported under Final Cut Express. DVCPRO HD, DVCPRO50, SD and HD card camcorder users as well as those shooting at 24fps will have to use Final Cut Pro HD.

Keyframes
In Final Cut Express HD you can only keyframe motion effects, not filters. Among video editors this is one of the most complained about disadvantages of Final Cut Express over Final Cut Pro.

Video Capture and Timecode
Final Cut Express HD will not display your timecode, nor allow you to batch capture or export video. Professional video editors will often want to batch record all of their clips at once onto the computer, with Final Cut Express each clip will have to be imported separately which can be time consuming for someone doing a large volume of video work.

Color Correction
In Final Cut Express you can not correct color using the three way color corrector. You can also not adjust the luminance or chrominance of your video or thin or soften your colors using Final Cut pro Express.

After Effects
One main draw of Final Cut Pro is its ability to work with Adobe After Effects Plug-Ins, Final Cut Express HD does not support After Effects plug-ins.


Mapping Keyboard Shortcuts
With Final Cut Express you can not custom map your keyboard 


Recording Your Screen Using the SMART Board Tools [Windows]

| No TrackBacks
Remember my post on using Camstudio?


If not, it was about using that software to record whatever is going on on your screen, and then save it as a video file that you can save with your students/colleagues, and it would be a great instructional video on how to use certain programs.

However, one problem arises: you are hosting a class, you suddenly realize that you need to quickly record something off your screen, and you do not have CamStudio installed (it is NOT installed by default on the classroom computers!).

Well, a quick and easy solution would be to use the "Recorder" tool on the SMART Board tools, which will already be installed on any classroom computer, and here is a video on how to do so!



Poster Printing Guidelines

| No TrackBacks
Introduction
If you have a poster that you need to print for a presentation or for advertising events on campus, then you can make use of the resources made available by Central Services for the Trinity community, located at the lower level of Williams Memorial. Central Services can produce full-color poster-sized printouts, suitable for presentations, advertising events and poster sessions.  Their poster printer offers high-resolution output, that clearly renders photographs, graphics and text. Anyone requiring services must provide their department's billing account number or, alternatively, students can pay with bantam bucks. For billing account numbers, please contact your department head or administrative assistant.

Fees
The fees charged by Central Services for printing posters are as follows:
$25.00 for a 24X36 inch poster or $30.00 for a 36X48 inch poster. 

Poster Templates
You can download 24X36 PowerPoint poster templates from here: 

How to make a printing request
Printing requests can be made through the my.trincoll.edu portal by selecting the Poster Print Submission link from the Resources & Services category.

Printing Guidelines
Before placing a printing request, it is advisable to verify that the poster meets certain criteria. Please look through the following list and make sure your poster meets these guidelines: 

  • If your poster is in a format different than PDF or PowerPoint, then you should convert your poster to one of these formats. For converting files to PDF, use Adobe Acrobat Pro and click on the Create button and from the list select PDF From File. Locate the file on your hard-drive and click Open.

  • Be sure to test your poster on a Windows machine, since that is going to be the type of machine Central Services uses to print the posters.

  • If your poster is a PowerPoint file, then you need to make sure that the slide(s) is/are the same size as your poster. Therefore, if you want to print a 2X3 feet poster, then you need to change the size of your slide in PowerPoint to 2X3 feet. In order to do this, in PowerPoint 2007, go to the Design tab and click on the Page Setup button. Type-in the width and height according to your poster size, select the orientation (landscape/portrait) and click OK. 

  • Pictures in the PowerPoint file have to be in one of these formats: .jpeg/gif/png. Usually, the jpeg and png formats provide better quality than gif pictures. To check the format of your pictures in PowerPoint 2007, right click on a picture, select Size and Position, and from the window that opens select the Alt Text tab. Here you should see the path to the picture on the hard-drive followed by the name of the picture and its format. To convert a picture to any of the file formats mentioned above, please use Adobe Photoshop to open your current picture and use Save As to save it to jpeg, gif or png. 

  • Make sure your graphics and pictures have a good quality, otherwise they will appear to have blurry or jaggedy edges. Keep in mind that printing a large poster requires pictures with large resolutions. 

  • If you copy/paste equations from Microsoft Word to PowerPoint, in some cases the equation appears as symbols rather than the equation you need. It is recommended that you use the same version of PowerPoint and Word to avoid any compatibility issues. Nevertheless, in some cases, the user does not properly copy the equation from Word. Here is what I mean by that: when creating an equation in Word, the text and all the symbols are placed in a text box->copying the text box does not result in copying the equation, such that when you paste it in PowerPoint it appears blank. To properly copy the equation, double-click the text box that the equation is in and select the equation and then copy/paste to PowerPoint.

  • Use common font-types such as: Times New Roman, Arial, Verdana, Garamond, Courier etc. If you use a font that doesn't typically come with the distribution of the operating system, then rasterize the text. You can do this in Photoshop by creating a new transparent file and pasting the text:  
  1. Open Photoshop
  2. Go to File->New
  3. From the menu select a width and a height for the document and select Transparent from the Background Contents drop-down menu. 
  4. Click "T" on the keyboard to select the Horizontal Type Tool, click somewhere inside the document window and paste the text that you want to rasterize. 
  5. Go to the Layer menu-> Rasterize-> Type
  6. Save your document by going to File->Save As and typing in a name for the file and selecting the format to PNG. 
  7. Take the image and insert it in the PowerPoint poster. 

  • Proofread the poster's content.

For additional information please refer to the Poster Printing Guidelines.docx or contact the STA office: e-mail: sta-help@trincoll.edu or telephone: x2589.

Take snapshots from movies

| No TrackBacks

Sometimes it is crucial that professors have snapshots from assigned movies. Through snapshots, professors are enabled to talk more about particular scenes or have their students identify important characteristics of different scenes. This blog will inform you how to take snapshots using different players on both operating systems supported by Trinity College.


VLC is an open-source, free of charge, multimedia player. Most Trinity College computers have VLC player installed, but if the one you are using does not, you could easily obtain it from the Internet.


Take snapshots with VLC Player


First off, we will find out how to take snapshots on a Windows OS platform.
Step 1) Play your movie (DVD, MPEG, DivX, etc.)
Step 2) Pause the movie at the scene you would like to take a snapshot of
Step 3) To take a snapshot, click on the camera button, which is the last one at the bottom row

Extracting Audio from DVD's and video files

| No TrackBacks
There are many different ways to extract audio but the easiest and probably cheapest (since the software is free) is by using VLC player. VLC is an open source software that is managed by volunteers across the world. As such, there are constant fixes and patches (which can be set to update automatically) that makes the software one of the best around. The fact that VLC player is based on a modular structure, so that even if one module is corrupt the others function unhampered, adds to its stability. VLC player is multi platform as well which means your choice of operating system (OS) will not limit the functionality of the program. The primary advantages/uses of VLC player include:

   
  • VLC supports all audio and video formats and all file formats supported by libavcodec and libavformat. This means that VLC can play back H.264 or MPEG-4 video as well as support FLV or MXF file formats "out of the box" using FFmpeg's libraries. Alternatively, VLC has modules for codecs that are not based on FFmpeg's libraries. 
  • VLC player can play all DVD regions.
  • VLC media player add effects like distortion, rotating the video, splitting video, deinterlacing, or adding a logo overlay.
  • Using a FireWire connection from cable boxes to computers, VLC can stream live, unencrypted content to a monitor or HDTV.
  • VLC media player can display the playing video as the desktop wallpaper by using DirectX (only available on Windows Operating Systems)
  • VLC media player can do screencasts and record the desktop.
  • On Microsoft Windows, VLC also supports the Direct Media Object (DMO) framework and can therefore make use of some third-party DLLs.
  • On most platforms, VLC can tune in to and view DVB-C, DVB-T and DVB-S channels. On Mac OS X the separate EyeTV plugin is required, on Windows it requires the card's BDA Drivers.
  • VLC can be installed and run directly from a flash or other external drive.
  • VLC can be extended through scripting. It uses the Lua scripting language.
  • VLC can play videos in the AVCHD format, a highly compressed format used in recent HD camcorders.

   The process of extracting audio is fairly simple and straightforward.

Click media --> Convert/Save
Now Add and select the Video file you wish to extract audio from
Then hit the Convert/Save button at the bottom
1 copy.jpgHit Browse and add a file name for your mp3. Make sure the file name ends with .mp3
Go to edit selected Profile
Set Encapsulation: MPEG 1, 
2 copy.jpg
Uncheck the Video Codec option
For the Audio Codec section, click on Keep Original Track
Hit Save and you should have your extracted file ready soon after. 


(Free) Photoshop Alternatives

| No TrackBacks
Free Downloadable Software
 
Adobe Photoshop is the best photo editing tool available. However, most users barely even scratch the surface as far as using the software to its full potential. Hence, it might be a bit of an overkill to spend hundreds of dollars on the software if all you are going to do is basic image editing like cropping images, creating panaromas, or touching up gamma and contrast levels. Here are a few photoshop alternatives that are perfect if you do not need advanced photoshop features and want to save some money in the process.

1) Paintshop Pro (Only for Windows)
Photoshoppro.jpg

Paintshop Pro offers a great array of features that might be overwhelming at first. This is due to the rather cluttered interface that is less than ideal in it's layout. As befitting a comprehensive photo editing software the program needs over 100Mb of installation space, so make sure you have enough space before you begin the installation process. One of the most helpful features in the program is the One Stop Photo-Fix option that automatically adjusts gamma, contrast and hue levels. A wide range of effects are also available to try out on your
photos.This program is perfect for professionals due to the highly detailed level of image editing possible. Casual photographers and image editors might find the learning curve steep but once they do, the program presents itself as an incredibly compelling alternative to Photoshop.

2) GIMP
Gimp.png

From the publisher:
GIMP (GNU Image Manipulation Program) is a freely distributed piece of software suitable for such tasks as photo retouching, image composition, and image authoring. It is a powerful piece of software with capabilities not found in any other free software product. It can be used as a simple paint program, an expert-quality photo-retouching program, an online batch-processing system, a mass production image renderer, or an image-format converter. 
GIMP is modular, expandable, and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image-manipulation procedures to be easily scripted.

Gimp is probably the oldest and most well known Photoshop alternative out there. Unless you are a heavy graphics designer who absolutely must have access to all Photoshop features, you will be hard pressed to find a better image editing tool for the price (which is free ofcourse!). The software is cross-plaltform, meaning you will find both Mac and Windows versions, and is supported by a group of volunteer developers (similar to Moodle) who add
timely updates and fixes which can be downloaded by the 'search for updates' feature. GIMP features include channels, layers and masks, filters and effects, tabbed palettes, editable text tools, perspective clone,improved printing, and color operations. A modified version of GIMP called GIMP Pro that mimics the Adobe Photshop layout is also available.

Online (Web-based) Image Editing Tools
Besides these downloadable Photo editing tools, a wide range of web based photo editing tools are also available.Even Photoshop has a web based photo editing program called Photoshop Express. We based tools offer many of the features present in the full downloadable program but obviously some features are absent. Case in point Photoshop
Express does not feature layers or channels. Web based photoeditors allow you to edit the images and then save the edited images on your computer. Be aware though that most web based editing tools feature some sort of restriction inorder to make you buy the full version.  

This application only works on windows, so no luck for mac users.
 
www.photoshop.com (Photoshop Express) 
This is the online version of photoshop. The web based application by adobe shares many of the features of Photoshop but lacks the ability to work with layers or form composite images amongst others. There is a 2GB file size limit.
 
A very popular image editing application that can count seamless integration with flickr (the online photo management and sharing tool) amongst it's most notable features.
 
An easy to use and easy to understand web based image editing application that allows you to conveniently crop, edit and add effects to images. 
 

Assignment Reviews-Electronically!

| No TrackBacks

The writing process entails many things, one of which is the review process. This process, traditionally carried out with pen and paper in hand, can be realized in a more efficient manner. There is a way to review assignments electronically, without the pile of papers and without wasting paper. Microsoft Word provides an ingenious and simple way of doing this.

This entry will go over the Track Changes feature in Word that allow you to review/edit an assignment in a legible and organized manner by tracking the changes that you make to it. This will essentially keep a record of any insertions, deletions or comments that you make to the assignment. With this valuable tool, you will be able to review, correct, and comment on any assignment from anywhere that you have computer access.

In order to review papers electronically, you will of course, have to have the assignment file. This entry will assume that all files are .docx format (although electronic reviews can be carried out with almost any file type using Adobe Acrobat Pro).

The following instructions are for Windows Word 2007 Users:

Once you have the assignment that you would like to review, you will click on the Review tab found at the top toolbar of Microsoft Word. From here you will select Track Changes in order for your corrections to appear in the document. This will track all your changes, from deletions to insertions, in an easy to distinguish red ink.

There are, of course, two distinct ways in which you can track your changes. The first is in what Word calls Balloons. The second is what is called Inline. The Balloon method will track your changes (Deletions and Comments) in "balloons" on the margins of the document. Any additions that you make will be visible within the main body of the document. The Inline method will track all your changes (insertions, deletions, and comments) within the document itself. Both methods are convenient and it is ultimately up to the reviewer to decide which one suits his/her needs best. Below you will find an image of both methods: the inline method is located on the bottom, while the balloon method is located on the top.

To change the way in which you can track your changes, simply click on the Balloons tab and select either Show Revisions in Balloons or Show All Revisions Inline.

You can add comments within the document by selecting New Comment. This command will add a comment to where your cursor is located.

Another possible feature that you could use in reviewing assignments is the convenient Accept/Reject feature included in Word. This feature gives you, as well as students, the ability to accept or reject any changes that have been made to their document. You can access this feature by selecting the Previous/Next buttons in the Comments section of the Review toolbar. By clicking these buttons, you will rotate through all your comments and changes in the document and you will have the ability to accept or reject them. The Accept/Reject buttons are located to the right of the Track Changes button.

When a change is accepted, Word will automatically incorporate that change into the document. When a change is rejected, word will automatically reject the change and remove it from the document.

Word also allows you to see different versions of the same file. In the first drop-down menu of the new Track Changes toolbar, there are four different viewing options.

Final Showing Markup: this will let you see the current edition, with markups of the file.

Final: this view lets you see the final document will all edits automatically included

Original Showing Markup: this view lets you see the original document with markups. All deletions will appear as strikethroughs, while comments will remain in the margin.

Original: this view lets you see the original document before being edited.

Once you have reviewed the assignment and made all necessary comments and corrections, you can easily write a final comment to the student, along with their final grade. You can do so by adding text (which will already be in red ink) at the end of the document.

Another feature that can aid in the writing process is Words Capability to distinguish different users and their edits. For example, if you were to send your student an edited Word file with, he or she could make further edits, which would be in a different color and under a different user name (provided that the student made the edits under a different name than the original edit) and return the document for you to re-edit. In this way you could quickly and effectively help a student's writing process with those longer projects or thesis.

Once you are done reviewing you can easily save the document and send a copy to your students. In this way, your students will have access to all your revisions and can easily edit their own work. If, however, you would like for your editions to not be tampered with, you can also save the edited word file as a PDF. Please look over the following entry by Dobromir-Save Anything in PDF! or my previous entry - PDF Files to review the process.
