As the thread title says really

I was just wondering "typically" how much processing do you do?
What do you find you need to do most often (lighten/darken/adjust colours/crop)
I know the idea is that we should, wherever possible get as close to the finished image we want while we are taking the shot, but, sometimes that is not going to happen (for me, it rarely happens

, but I'm hoping it will get better as I take more photos

)
