change to b&w with 1 color
In CS 5 how do I make a color photo B&W, keeping an item in that photo in color (can I also change that color)?
1. Make your basic selection with some sort of lasso.
2. In layers, click the black/white circle (masks) icon and select black & white.
3. Grab your paintbrush and paint black on the mask for color, white for black and white.
And yes, you can change the color, but there are so many ways to do that that I'd have to know what you're trying to do to tell you the best way to do it.
