CS2 Desaturate

Postby Pehpsi on Mon Nov 27, 2006 11:56 pm

hey,

i just tried my first desaturate then colorize by doing the following:

desaturate > new layer > colorize

it works good. but is there a way to get back the original image colour instead of having to pick your own through the Hue tool.

EG: the pic is of a cat. i want to desaturate the whole image but just bring back the original colour in the eyes?

cheers.

Jamie - easiest way is to do your desat as a new layer over the original, and then you can erase the layer over the eyes to reveal the original colour :).....
hope that makes sense :?
it does in my head ;)

That's a nice result.

A small refinement to that technique would be:
  1. Add Hue/Saturation adjustment layer, setting the Saturation to -100.
    (or use the same New Layer, Desaturate you had)
  2. When you add an adjustment layer it will automatically have a mask.
    If you've used a normal layer, add a layer mask to it.
  3. Don't erase the top layer, but instead paint black into its layer mask.
    That way if you make a mistake you just paint white back in and the "erased" bits will "un-erase".
The final result is the same, but it's a bit more flexible.

Another easy way would be to desaturate and then use the history brush just on the eyes.
