Apologies for the really daft question again...
I am not intending to get into the depths of post processing just yet - I need to learn to take pictures first, after all! However, a lot of my photographs just need a little tweaking on the computer as the colours rarely seem to be quite what they were to the eye.
Anyway, I wondered if someone would be kind enough to point me in the right direction of somewhere I an learn about curves, please. I am forever seeing images described as 'just adjusted the curves' but I have no idea what this means! What is a curve in terms of image processing, why would one edit it and how?!
I have searched the web already, of course, but all I can find is tutorials about 'adjustment curves' and nothing at a level that satiates my simple mind and explains the very basics!
