Try to make sure your light source agrees with your film type. That is if your subject is under fluorescent lights and you are using daylight film you should use a filter to compensate. If you use a filter you will need to adjust your exposure by about a stop. Experiment. Your local camera store can help you with filters.

If you can, purchase daylight bulbs and use daylight film. This should give you more accurate color. Also, try to eliminate other light sources that may contaminate your light.

If you use a digital SLR you can still use daylight bulbs and use the white balance for daylight, still eliminating other light sources.

I hope this helps.
