Bob... nicely executed bowls.
As for your 'white balance' problems ... Be sure that ALL your lights are a) the same brand manufacturer, or, 2) the same type - don't mix fluorescent and incandescent bulbs, 3) they are about the same age, 4) they are all the same wattage, etc. Also bulbs in a reflector type shield MAY tend to overpower some nearby bulbs and cause exposure problems.
Try moving your lighting around and see if you can get a better mixture of light. Moving back from your area being photographed will only cause you to make exposure adjustments and refocusing.
IF you are using a digital camera, and this day and age is there anything else, you can try to bracket your exposures ... that is make one shot at each of the apertures on your lens. If you are using the automatic shutter feature - where the camera selects the shutter speed - you should realise a greater depth of field at certain apertures that are better exposures that the others. These 'areas' will be the prime exposure range of your particular camera. They all vary, but the lens combinations all have their 'sweet spots.'
IF you are using a digital camera the only thing you are 'spending' is time on making the aperture adjustments. BTW, these changes will show up much better on the PC monitor that they every will on the camera's viewing screen.
Have fun and experiment until you get it right! :biggrin:
