On another note photoshop CS3 aparently has a new formula for brightness/contrast than doesn't clip shadows/highlights as quickly. That might be good for FF as well. Anyway here's a snippet that breaks down what brightness does for those that are curious.... Brightness Explained.ffxml

BTW we've just finished a help article on tone curves that has examples with brightness and contrast: See 'Example 2' for brightness and 'Example 3' for contrast: http://www.filterforge.com/more/help/...ained.html
