These seem like simple things to do, but I don’t see the route to do it. Possibly Photoshop CS can do this more readily, with its ability to match colors in two different images.
CASE 1
I have an RGB image, and there is an area in that image that I would like to have the color 128-128-128 (pure midtone) gray. Let’s assume that it is presently 97-140-130. It would seem that if I went into COLOR BALANCE, and used the sliders that I could do this. But even checking "midtones", and unchecking "preserve luminousity", it’s not always possible. Also, I would think that if I moved the red slider 30 "units" more to red, that the image test point would move 30 units also, but it’s never 1 to 1.
CASE 2
I have an RGB portrait image, and I have an RGB readout of a skin tone, but I don’t like the color. I then open another image of that same person, and I’d like to match the skin tone in the first image to the skin tone in the second image. How can I simply match the first to the second? Will this be easier in Photoshop CS?
CASE 3
How do I go into an image, create a test point with the sampler eye dropper, and then "dial in" a change in color in the info and color palettes, or wherever?
