Photshop question!!!!?

Question

how do i make my whole picture black and white, except for a certain color like yellow, and green or red...or blue with the rest being black and wihte?

Answer 1

What I would do is take the magic wand or the extract button and then place my selected material, with the color in it, on another document. Ok, say you should be able to get a clear extraction (a tanned girl with a white background)...take the magic want and take the tolerance to 20-50 pixels. Now, select the white background...all spots while pressing SHIFT. Now go to "select" and click "inverse." Now you have a clear extraction. If you don't, you can mask or extract. Put this selection, by using teh move tool, into another document of the same resolution of the picture.

Now look at your original picture document. Go to Image, then Adjustments, then DESATURATE. You now have your original picture in B&W. Using the move tool, move your colored extraction into your desaturated picture. Move it to where you want the color. Save as a JPEG to merge the layers, or if you want to edit it later go to LAYER and then MERGE VISIBLE...so that this color portion is perfectly on there and will not move. To get a precise place, select the selection tool and move the arrows on your keyboard. This moves it pixel by pixel.

Note: THis was done with 7.0, but you can do it with all versions of Photoshop - 5.0 would be a bit difficult, but it is still feasible. These commands are compatible with all versions (not CS3, not sure about that one -maybe), just they might be in slightly different drop-down menus. 8.0 will definitely do this, but the drop-down menus hold slightlly different commands. If I remember right extract is under select, but i'm not sure. You can definitely mask or quick-mask.
