I'm in the process of writing the 2nd part to a previous article on Photo Editing With Histograms and it basically centers around the curves adjustment tool found in many pieces of photo editing software. The problem I'm having is determining how deep to go into the topic — curves can be highly technical and complex if you start from ground zero.
So help me out with this poll and let me know your experience level with curves. I'm assuming that most of you know what it is and how to use it, but with an audience this size it's hard to tell for sure. If I see a lot of people with absolutely no clue, I'll try to include some of the basics in the article. But if the majority is already familiar with curves and how they work, I might trim that stuff down and just give a few links to other articles that cover the fundamentals.
And if you have any specific questions about curve adjustments or how they relate to the image/histogram, leave a comment and let me know! Hey, I can't answer your questions if you don't ask.
