This is driving me mad, new to CS5 but have used various other programs with mask feature, I can select a quick mask with the colour set to white and black, on the black it will highlight in Red no problem but on the white it won't hight light in green, it does remove any red but won't hightlight in green for an area I want to keep.
I was trying to make the whites of the eye whiter by creating a quick mask and highligting the whites in green (so with the white colour selected) and then adjusting the levels for the selected area but it just won't work.
Looked every where for an answer.
Apologies if this is in the wrong area as never posted before.
