Hey everyone.. I have two old ass lights that my uncle made back in the day like in the 60's and I have an SB-800 flash. I'm trying to figure out a way to use these 3 light sources together... I'm not sure if this is possible. When i set them up (simple 3:1 lighting ratio) i find that i either get really blue picture or a yellow pic. I know its all white balance and two different kinds of light sources.. I was just wondering if someone had an idea or a way around it.
also... i've been putting up posts like this for awhile and some of the members have been pretty rude with answers.. so all I ask is that if you think this is a "stupid" post please don't reply.. i'm not being an ass.. i just don't like getting treated like i'm a moron when all i'm trying to do is learn like the rest of you. |

You need to get CTO gels and then set the white balance to tungsten.

I'll try not to be an ass, but for some people here, it comes so naturally and so easily that they just can't help it.
What I do when using I have two light sources of different color temps that I need to look the same is to color correct one of them using a colored gel or gels.
In your case, you want to make the flash match the tungsten lights, so you need some Full CTO (that stands for Color Temperature Orange, I think) gel over your flash as a starting point. That should give you pretty good results, but if you need more precision, you can get 1/2, 1/4 and 1/8 CTO gels and make different combos until you get it how you want it.
I use the Rosco cinegels, but I think there are others. Just cut a piece small enough to tape over your flash head and go from there. |

You can get a free sample pack from Rosco here for small flash heads. If those old lights are large Rosco also carries them in large sheets you can buy.
You may always want to check your local theater group and see if they have any gels they don't need.

| I thought this is what your Custom White Balance setting is for -- set up your lighting, place a gray (or white) card near the center of the subject area, and set your custom WB to that. Whatever the mixture of light colors, the camera should then attempt to correct it to neutral white ... |

It's hard for the camera to take to take in two color temperatures and render both combined as "white." I've used custom white balance in conditions where I'm bouncing a hotshoe-mounted Speedlite and still letting some ambient in, and that works pretty well, but that's a subtle situation.
With two hot lights and a small flash, the hot lights are always going to override the flash in terms of color. Custom white balance may lend a somewhat less extreme color, but a CTO gel will be required to balance it enough for the camera to even out.

Your camera can only have one color temp as "white". In this case, if you set the WB to tungsten, you'll have areas illuminated by the flash as blue. If you set the WB to flash, you'll have the areas illuminated by the lamps yellow. If you try for something in between using a custom WB, the only areas of the image that will be neutral will be those receiving the exact mix of tungsten and flash light, the rest will be blue or yellow, depending in how much of each light source illuminates that area of the image. |

If not, let me know, I have a large sheet of Full CTO and I'll send you enough to cover your flash.

The one that comes with the SB800 is the CTO gel. It works quite well. The Rosco ones have more variation though, so if you find that the temperature is still off a little, grab a rosco sample pack and mix/match the gels until you get it right. |
