Here you will find some help and links to pages that will help you understand the material for module 2.

General concepts on Computer graphics, focused on Web Graphics.

COLOR

This is a simple but interesting page that will help you expand the way you define Color when working on Computer graphics. It uses the color picker in Photoshop:

SCREEN RESOLUTION

Color in monitor-displays is represented as a combination of the 3 Additive colors: Red, Green and Blue.
(RGB signal)

RESOLUTION (II)

Screen resolution versus Printing resolution (dots per inch: dpi)

Considering the resolution (size) of page-design for web.
Notice that web pages don't have an absolute size: The browser window can be resized by the user.

Also, a given design, let's say of 800X600 pixels, would look kind of small in a monitor that displays 1280 X 1024 pixels, but barely fitting in an old small monitor, that displays 800 X 600 pixels (I know, this size is obsolete, but I just want you to get the point that graphic size is relative over the web)

COLOR DEPTH

Color depth applies to graphic files (how many different colors a graphic file can store) and also to displays

(how many colors a graphic display can present, independent of the file.

WEB SAFE PALETTE

A web-safe color palette might sound to you like a Jurassic park concept since most computer-monitors can already display millions of colors.

Think about all the other electronic screens or monitors. many of then can only portrait very limited amounts of colors, this is why the principle of a web-safe palette is important again.
