Photoshop...black & white & color?

Question

I know how to make a color photo black & white, but how do I make a specific part of that picture colorized?

Answer 1

I would use a separate layer (new) and air brush the color in for say, the eyes then back off on the opacity until it looks right. Do the same for the lips, hair, grass, trees, whatever. Just make a new layer for each colorized segment so you can assign varying opacities to each part.
