So--
in the iphoto's application, there is an edit feature,
And within that:
Brightness, Contrast, Exposure
and Levels.
i think i have a good idea of what Brightness, Contrast & even
Exposure are/do...
But Levels completely baffles me.
i've looked and compared the graph to the pictures and i can not see
any correlation whatsoever...!!!
What is that representing...???
What does the x & y axis' represent...???
Thanx!
