They work the same way in every application. Learn them once and you can use them everywhere. The way I learned how curves work is by somebody drawing a line to indicate the brightness of a pixel coming in and going out from the effect. You can use curves controls to adjust individual color channels, too, but let's just start with the overall luminance. What's rarely clear in a curve control is that it's kind of a graph, with the horizontal axis representing the level of the original image, or let's just speak about an individual pixel, and the vertical axis representing the resulting output level once an adjustment has been made. You'll notice the default set-up has a line going neatly from not percent to 100%, so no changes are made…
