Reproducing the effect of sunlight indoors on the cheap is not easy. Tungsten sources are too yellow, cool white fluorescents are too cool, grow lights are too red. Mixing different colored sources in various combinations can yield satisfactory results. Wide spectrum fluorescent bulbs are available but are not a panacea. Direct sunlight streaming through an unobstructed window can be nice to work with if you can arrange it.
Clouds are great diffusers.
Of course you can always shoot outside in the sunlight, but depending on your situation this may require you to record the shot and frame grab off tape rather than the undegraded live signal from the video camera. Special white light sources for studio photography are available from photographic equipment suppliers, but they don't exactly give these lights away. The frame grabber used to capture the first generation of specimen images of rocks in Bob's collection was a now discontinued 16-bit half size ISA card called the Captivator that was manufactured by Videologic . VideoLogic has since discontinued the Captivator , citing unavailability of electronic parts discontinued by manufacturer as the reason. They do not have an direct replacement at a low-end price point.
