I am trying to adjust brightness/contrast in photo/video editing software that does not provide image histograms. What I would like is a piece of windows software that displays a real-time histogram of all or part of what my monitor is displaying.
This could also be useful for other things, like for example evaluating the tonal distribution in demoscene productions, Windows theme development/tweaking...
Of course I could :
1 - Evaluate histograms of screenshots in Gimp (very tedious because non real-time)
2 - Point my camera (with real-time histogram enabled) to my monitor (...)
So, do any such tools exist, or do you have any insight on how I could go about achieving this ?
