Hi Ross, Photo supply stores offer "daylight bulbs" which simulate sunlight pretty well, and can be used with daylight-balanced films. Like any commodity, some are better (and more expensive) than others. Good quality daylight bulbs might cost $10.00 each. As Enzo said, there are filters that can be placed over ordinary photo flood lamps to produce daylight quality illumination, but this is the most expensive way to go. Daylight bulbs are actually incandescent bulbs which are either coated with such a filter material, or have the material incorporated into the glass itself. These filter out a lot of the longwave light produced by an incandescent light source, resulting in a cooler (bluer) output, close to daylight quality. As you said, such bulbs do get very hot during use. They have to have a high wattage because so much of the light produced by the filament is filtered out. Still, I have found that these bulbs do last quite a long time under normal usage on a copy stand (turning them off between exposures - which you will want to do anyway, to avoid being cooked while positioning the next specimen). Another option is to use ordinary 3400K photo floods, or 3200K tungsten lights (ordinary home light bulbs), with a color correcting (blue) filter over the camera lens. This is the cheapest way to go in the long run (you don't have to keep replacing expensive bulbs), and gives good results if you purchase a good quality filter. Unfiltered fluorescent illumination will give your pictures a green cast, but such illumination could also be used with an appropriate filter. Such a filter would probably be harder to find for your camera though, since these filters are much less in demand than tungsten filters. Also, the color range of a fluorescent tube changes as the bulb gradually warms up during use, whereas the color output of an incandescent source is constant. Some top-of-the-line digital cameras have built-in color correction. You set the camera for the type of lighting you are using, and the camera makes the necessary corrections. Paul M.
