I am still playing with Adobe PS CS5 and my demo time is nearly out/up.
I have started to get into it a bit and when I load a file I get an initial screen where I see the image and I can adjust the and all that stuff.
White balance, "Temperature", , recovery and stuff I don't yet understand.
In the top right of the screen is a graph of the three colours and as I move these sliders below it, the graphs move.
So, starting with the initial load: Say the graphs are "scattered" and they all peak at different places.
More luck than knowing, I am seeing that if I fiddle long enough and try to get all three overlapping the picture looks "better". I say "better" because sometimes when they don't line up it also looks nice, but that may fall into an ARTY catagory rather than a true representation of what was really there.
Now, looking at the sliders: The first one - Temperature - is coloured BLUE/YELLOW.
Moving this left/right SEEMS to move the BLUE peak in the graph left/right.
Is this realated or is it just a coinsidence?
Also I haven't started to play with the other buttons JUST below the graph. I am only playing with the "BASIC" stuff. "Tone curve" and "Detail" etc haven't been looked at yet.
