Previewing Gamma and Browser Dither
How is the image going to look on the web. Lesson 5 deals with what the browser does to the image when you see it on the web. This is important when you examine how the file will look to someone with a different system than what you have. Sometimes the colors can change in a bad way when you look at them on one system and then a different one. This section highlights the differences. When you finish it come back to this page.
Lesson 6 deals with changing the image size. I use this quite often when I am trying to make an image fit on the screen. It is important to note that you must make sure the Constrain Proportions box is checked or the image will look too skinny or fat, too tall or short because you only changed one dimension or didn't change both dimensions with the same aspect ratio.
