yes end no
LEVELS are much more compliated , but Droppers yes ther are 3 of them 1 white 1 black 1 grey - if you got all 3 of thous as a markers on the photo - just drop them wich will mean for a program " black with hue of blue = black , White with hue of blue= white, etc .. so it eliminates eny hue changes made by light
but on thous protos of yours ther is a lot of wrong setings like Aperature of 2.8
end they aretotaly over exposed
I have tried to play with my hubby's Digital SLR but I actually get better results from my Kodak!
- thats normal cos "monky camera" got better depth of vision
a baccground color vs whole proto temperature - wel thats old discusuion from optic

but this efect mey be eliminated by solid setings of WB - in camera
BTW what SLR it is ??
end about Dropers ... worked on Gimp end PS ... you know what - they work better on Gimp ...
EDIT
