Photoshop question

Hey all of you photoshop guru’s out there…
I have a question and I hope you can help. I’m wondering if it is possible to remove a specific color from an image…

What I’m trying to do is take a photo of one of my models in front of a “green-screen.” I’d like to be able to remove that background color so that only the image of my kit remains. Now I know I could go in and try to outline the kit manually, but I figure there has to be a better way of doing it.

I’m using photoshop 7…but if you know how to do it in a different version, please tell me anyway and maybe I’ll be able to figure it out.

Thanks in advance gang!

CHEERS!

I use Photo Adobe which has a magic wand feature that will select odd shapes. Once it has done that I can right click the selected area, invert the selection and there it is. Never played with photoshop but would think they have a similar feature.

Oh yeah, I like blue screen better because if a small spot gets included it will disappear into a sky setting real easy.

Thanks swanny! Thats a great point about the blue screen… I never would have thought about that. Thanks again!

In RGB mode view each channel separately, find the channel in which your green screen is most prevalent and duplicate it into a new channel. Use the curves function to accentuate your green screen areas. You may also selectively use the erase tool to delete non green corresponding areas in the channel. If you don’t end up with a tight enough mask you can run the minimum or maximum filters or you can blur the channel and use curves again to tighten your mask. Once the channel is modified to be just the green areas, command(mac) or control(windows) click the channel and it becomes a selection which you fan fill with your background image or delete to releal another layer. This is sort of complicated way to do it but it gives you the best quality. I’ve used this method to replace sky in images of trees with sky showing through a lot of branches. I can clarify if my description was confusing. This is sort of advanced Photoshop and easier to demonstrate than describe. Once you get the hang of it you can do it very quickly with much better results than the magic wand tool.
