Green Screen in Photoshop

fredjclaus

Well actually I use Paint Shop Pro, but I was wondering if someone could help me. I just got a contract to do dance school portraits this year and they want to use my GreenScreen services. Trouble is I only have green (no blue) and some of their costumes are green/blue in color.

Can someone give me a tutorial on how to remove a green background in photoshop(PSP)? Right now I just use a program called Green Screen Wizard that automatically removes all green. That wont work in this case though.

It's either this or I just go out and buy a solid white background to shoot with.

Select: Color Range
Play with it. In combination with the other selection tools, in additive and subtractive modes, it's really fast and simple.

If the greens of the uniforms and the background are too similar then automation may not work very well. Some people have had pretty good luck using blue tarps instead of a "genuine" blue chroma key background. Just make sure that you have enough separation and no wrinkles and properly lit and it should work pretty well.

The plain white background can also work well as long as there are no whites in the uniform that intersect the background. White works nicely because there is relatively little noise in the highlights (... or there should be little noise anyway), and you can fairly safely bleach the background as long as you avoid sensor bloom/smear and lens flare. Another nice thing about using a white background and luminance key is that if the keying process doesn't remove enough white and leaves a halo around the subject, you can generally just run a "Burn Tool" around the perimeter to tone down the halo and it will meld a bit better with many digital backgrounds. With a chroma background the color halo can be a bugger to eliminate and any color poisoning can be a killer.

fred...do you ahve at least 3 lights for lighting this.......if so use your largest umbrella / modifier for you main front light......
and 2 back lights....spend $10-12 on a couple of sheets of colored gels and just recolor the backdrop....that should be
cheaper than buying a new backdrop.....unless your looking for an excuse for a new backdrop...... :-}}

Gells would be an option too. I have to get to the camera shop and see what they have.
