I have 2 SB800 Nikon flashes. Is there anyone who has used 1 on the drop and 1 on the subject with success? The flashes have the ability to sync so I could underexpose the drop. My background is on it's way so I am just trying to get some info before downloading the software.

You are asking in the right place. My guess is that no one has tried it, and that's why when you asked if they had, you got nor response. Also, many users aren't on here every day, so perhaps someone has tried it but hasn't seen your question yet.

Your best bet is probably to try it out, using whatever backdrop you might have on hand, and see how the results turn out. Or, wait until your greenscreen arrives and try it then.

Thanks. I should see my green screen on Monday or Tuesday. That will give me an opportunity to try it out before a shoot this weekend. Thanks for the reply. Is there any advantage to downloading PhotoKey now? What I mean is, are there things to learn about the software BEFORE the actual screen arrives or is it really "hands on" with the background?

It couldn't hurt to get a bit familiar with it, I suppose. I don't think there is any disadvantage to downloading it now. Its relatively simple software, and shouldn't take too long to get the hang of, but you could read the manual before you dig into it. And once you have registered, you can download it again any time you want, as many times as you like.

I have used an SB800 on remote to light up the screen and an SB600 for the model....works fine. Other than that I am quite happy with the program except that I wish the default background was not black. It is hard to see if you've managed to drop the entire screen. Or am I missing something?

We've experimented with strobe lights to light the background and have had some success. We prefer to light the background with continuous light at about 1 stop below the subject. We then use a variety of different strobe arrangements to light the subject.

It's difficult to get the strobes to evenly light the background. You would need two to eliminate opposing shadows. It can be done but take a lot of trial and error. Continuous light allows you to better stabilize the background. Strobe works well on the subject and keeps the heat factor down as well.

You can see some of the sample photos we did at http://chromakey.ning.com/photo

PhotoKey does default the background as black (it's really transparent). However, sometimes we use a white block as a temporary background while we are tweaking the image.

PhotoKey has some great tools to color grade foregrounds and backgrounds to allow them to blend naturally.

The results are obtained when you can light the background and the subject is an outline and when you light the subject, the background goes dark. That keeps the spill down and lets you evenly light the background. Now, with that said, I have used SB800s (2) successfully with the subject way too close. But it did spill green on the edges. I have had much better luck is using a couple of cheap softboxes shooting across the background at something like a 45 degree angle. Then lighting my subjects with a couple of strobes in umbrellas. I have not tried continuous lighting.
