strobes, chromakey and hot lights?

[chadgeek]

haha, ok. I was wondering if I would run into problems with this.

I have 2 strobes to light a subject and 1 off camera flash to light a chromakey background. I just need to light enough of an area for a headshot.

Since I'm going to knock out the background in post, do you think I would run into any spill or color balance problems if I use some photo hot lights to light the chromakey?

the background is a non reflective professional background, and the subject is only about 3-4 feet from the background.

I was able to key out the background without ANY background light, but it took some tweaking that way :)

How about one strobe on subject and two at background at even distances at even power, probably through a softbox/umbrella to ensure even light.

The hot light will be a waste of time.

If you're using a shutter speed appropriate for human portraits, a very weak strobe will obliterate thousands of watts of tungsten.

thanks Austin and Curtis.

I have a severe space limitation so I can't open up another umbrella in the room, haha. I think I'll have to move the bed into the patio. Hmmm. Sounds like fun.

I use two rooms in my house to do portraits. Backdrop, subject and main light in one room, camera and fill light in the next.

Don't light the background. Light the subject the way you want and put them about 6 feet in front of the bg with the lights another 7 feet from the subject, this gives you a bg exposure that is one stop under your subject and makes knocking it out a breeze.

Guess I'll have to set up in my living room or garage then, as the room I am in is too small cause you're talking a minimum of 13 feet. Sounds like it's worth it though.
