I am trying to set up some sort of small studio as cheaply as possible. My objective is to take stock type images with bright white backgrounds. I bought a clamp light with a 9 inch wide reflector and a 100 watt clear bulb and some other stuff like a large white kitchen type tile and a 12x12 mirror. My images are turning out with a yellow tint. I tried everything I could think of, slower shutter, using fill flash, put the light at different angles, etc.. Is it that my camera is not dlsr and not equipped for this, or is there a lighting issue, or what? Here are 2 examples. These were taken right out of the camera and resized, no editing, auto setting and no flash was used. ANY help is appreciated.

I have found pretty good success by buying a couple umbrellas, painting them silver on the inside, and attaching them to a couple tripod stands.

Then I mounted my regular flash to one of the tripods (aiming into the umbrella), and I fire it with a wired connection to the camera.

On the other tripod, I have mounted a really old flash unit that I have, and I bought a wireless slave device for something like $20, so it automatically fires when the other one goes off.

This set up is relatively cheap, and has worked tremendously well! I had originally tried just using the halogen lights pointed into the umbrellas, but I was running into the same kinds of yellow-ish problems you're seeing.

Have you set your white balance to tungsten or better still, can you take a custom WB setting with your camera? The yellow cast is often because the camera is set at a WB that is for sunlight. Check that first and then you can start to finesse things with the lighting itself.

I am no expert, but it's the white balance, the s5000 has got the ability to adjust the WB but you'll have to use the manual modes.
Your lamp will be emitting a tungsten light, which will always show like this unless you adjust white balance.
If anyone know of a better explanation feal free.

I tried this. I tried it in every setting that was available, sun, 1, 2, 3, etc..

Before I went with the method I described above, I still had trouble no matter how I set the white balance, too. I could get *better* results with certain settings, but they don't compare with the method I've been using lately...

I have the S5000 as well as a D70, I have had a play and the best results are from the top most setting(the little bold sign), you'll have to resort to using more/powerful light sources.

so I need More light? like halogen, watts, or what? I appreciate alansfreeds comments about the umbrellas, but I do not have wireless flash, my flash is built in the camera. Is there anyway to use wireless flash with my camera? I plan to go dslr soon.. but kids just get more and more expensive to raise hehe :)

DSLR and flash units are the way to go. Most importantly, make sure your light is diffused! Light straight from bulbs is harsh and shadowy, diffused light is essential.

i beleive your fuji does not do a pre-flash under normal conditions.
SO, you can use optically triggered slave flashes.

Ritz sells little ones for $15 or so. very tine, very inexpensive and i'd imagine not powerful. but it might work.

ebay - the budget photographers best friend. any flash - i have some quantarray ones i got for about $20 a piece. vivitar 283 or 285 are very good. if the flash unit does not have an optical trigger built in, you can get the equivalent of a wein peanut for about $10-15 that will trigger the flash via the hot shoe.

If you add up all you need above, it should still be under $100 and will be useable with your future dslr.

if you want to stay with 'hot lights' go to sear. they have a halogen worklight for $29 (usually on sale for $19 around fathers day). It is 2 lights on a 7' stand. this one here. Get 2, and get a couple of cheap white sheets form walmart ($3 each) and they can be used as difusers or to bounce light.

My hot lights were used for these shots (using a fuji S602)

I shoot some stock stuff pretty much the same way... Clamp lights etc... I have a make shift box made of pure white foamcore boards 5 sided (left, right, back, top and bottom...I will point the light in the open side at the top or a side not directly on the subject. Custom white balance is the only way for me to get it right... I set the Custom WB to the white board directly behind where the subject will be. Still a tad bit dark but they come out truer white.

What you need is a different color light. I've seen a lot of different valuses for regular incandescent bulbs (2750K to 3400K). Some of the bulbs that claim to duplicate sunlight may have a higher temperature.

But color temperature is not a great measure, see //www.topbulb.com/find/cri.asp for more details.

You could use any lights and "photoshop" to adjust the color. Just put a white (or grey) card somewhere in the image, and use the "click white balance".

Just out of curiosity what color are your walls painted?

they are offwhite, but these images are infront of a new solid white tile.
