I am still in the training wheels stage, and have question about lighting. I have a cheapie set of smith victor lights (using 500w bulbs). So far they have been good-- but I was hoping to try out Rolando's "home depot" light setup. If I use the fluorescent bulbs as my main light and one of my smith victor lights as... for example a kicker, what pitfalls or remedies should I watch for? Can I assume that as long as I white balance with both on that I should be fine?

Again, please excuse me if this is a knucklehead question

Thanks!

I don't use much artificial light myself, but I think you are going to have color balance issues. It wouldn't be a problem if the mix were constant across the image, but you will be having more of one bulb's light in one part of the image and more of another's in another part. Let's say bulb type A is more magenta and bulb type B is more cyan. Some of the image will be too magenta, some will be too cyan, and some will be a variable mix of the two. If you correct for one area, you'll mess up the rest of the image.

Maybe someone has a way around this I'm not aware of, but from what I've seen, it's best to use all bulbs of the same type.
Or go b&w.

One simple approach is to just put an appropriately colored gel over the Smith Victor light to make its light match the fluorescent. Then you'll have no WB problems. But sometimes one wants the variation in light to simulate real world conditions. Do the CWB for the pre-dominate light source, in any event.
Cheers,

Thanks for the help, and the thoughtful answers. I am going to try out the lighting this weekend and see how it fits!

Unless you use the more expensive daylight balanced fluorescent tubes, you're going to get greenidh light from your main light and orange light from your kicker. How're you going to balance that out?

Even the daylight balanced tubes have a bit of green tint to them, by the way.

Here's one I shot where I used daylight-balanced tubes in a four-square array as the main light and the modeling (incandescent bulb) light from a strobe as the kicker (notice the extra light hitting her head and left shoulder) - basically what you're wanting to do. But I don't think it would have been possible to get the same colors with normal fluorescent tubes.

Thats a fantastic photo-- and is exactly what I hoping to achieve. I'll try playing with some gels on the kicker and see how it all comes out. Thanks for the tips!
