Identify task requirements, apply search strategies, and use current technology to efficiently acquire, analyze, and evaluate a variety of electronic information.

Technology teachers must attempt to keep up with current technology and be able to demonstrate to students that everything changes quickly in this field. The World Wide Web (and the myriad search engines available) makes the location of information much faster and easier than it was when I was in school and there was not a computer on campus. However, there is so much information (good, bad and indifferent) available that it is even more vital today to be able to evaluate the information we locate.

Artifact #2

Descriptors: Digital Graphics, Web Authoring

Title: Digital Graphics -- Image Report

Course: Digital Graphics/Animation

Date Created: October 15, 2002

Source: Internet, readings/research from Module 1 in the Digital Graphics and Animation course

Media: Adobe Photoshop, Dreamweaver 4

Description: In this activity we were given three options to choose from to research and discuss: Image File Formats, How to Capture Images (Various Methods),File Sizes and How to Reduce Them While Maintaining File Integrity. I chose to research the file formats: Areas to be covered were the following:

4 or more formats presented
description
platform
advantages
disadvantages
representative graphic examples
2 or more URL links
summarize topic
The file types I have compared are the following:

• .jpg (Joint Photographics Expert Group)
• .gif (Graphics Interchange Format)
• .tiff (Tagged Image File Format)
• .png (Portable Network Graphics)
• .bmp (Windows Bitmap)

Rationale: I include this artifact because, while I was aware of the different filename extensions when we started the course, I was not aware of how very important they were. Balancing loading speed versus image quality is the same problem faced by "traditional" photographers who deal with film speed versus print quality (faster film speed produces photos in poorer light, but at a cost of grain size in the print), so once I viewed it in that light, I had it cold. I had also heard the term "lossey" before, but was not sure exactly what it meant. Obviously, now I do, so my family photos will go into the computer as TIFF or BMP files (even if it does eat up space).

Implications for future: This activity proved to be very informative. File format is much more than simply the extension that is given to the image file. One type may give a totally different appearance than another, and some formats are not supported by some programs or media. For the webmaster, it is crucial to understand the different file formats as they relate to image size, and students need to be aware of these considerations.

Reviewer's Comments: Cliff, your black on gray was very soothing to read. I like it much better than black on white. I wonder if I will ever get all those acronyms straight in my head. Your presentation was a great start! Thanks.
