I've used chroma key in cinematography before, and have software for video CK, but I'm curious to see any examples of chroma key in photo form.

What chroma background did you use, and where did the background you inserted come from?

I have chroma blue and chroma green but I've only used them once and wasn't really happy with the results. I had too much splash from the chroma backdrop and it made it almost impossible to isolate the subject. I learned the hard way that I am not very good at popping someone from a background. And I learned that lighting the chroma backdrops is very critical. As for the inserted background, I have a few CDs that I bought off of EBay but again, I wasn't happy with the knock out so I never have used them.

Chromakey backgrounds for print just aren't worth what they charge for them. I have a lot of example on my website where I replace the background with another images, and I never use Chromakey. best advice I can give you is to match the background to what you intend to replace it with. For example, if I shoot a model in the studio and know that I'll be placing her in front of a sunset, I shoot her against a yellow or orange background so that when I knock her out of the background any color ast looks normal.

In the example below, was one of my first attempts at a location-style shoot. The model is kneeling on beige carpet in my livingroom studio (few handfuls of dirt helped add texture). The background is sky blue seemless so I could match it in post production.

I have a Chroma Key geen and have never been able to get the results I expected from it. I have found that a high-key background is easier to work with in PS. THe green tends to blead into the hair too much. But white wont cause the same color bleed. The hard part then becomes getting the new background at the right angle and zoom so that it looks natural when you place th subject on it.

And I especially admire your PS skills in taking a "kneeling" model and re-configuring her to make it look like she's laying on her side.... [img]/ubbthreads/images/graemlins/wink.gif[/img]

BTW, who/where is the model? Sort of looks like Jessica Conzales.

Thanks
