lighting vs film colors i want to copy some of my earlier work, to have negatives of them again. I have the setup all ready, but need to know which lights and filters to use. I have read alot about various situations, but havent seen a list for different types of lighting, like flourescent, and the standard household bulb. what do I use to keep the copied prints from comeing out blue, yellow, and so forth? and what are the corrective actions for the various types of lighting? (i cant often choose what type of lighting ill be working with)

This will probably require some experimentation. I don't recommend using a fluorescent bulb! It will be very difficult to color balance to this. If you use incandescent lights, try to use floodlights of about 100-150 Watts (in floodlight sockets that can withstand the heat). These will be closer to studio tungsten photo lamps and easier to balance. The traditional tungsten-to-daylight balancing filter is an 80A and you may wish to try that first. It would probably require some work with whoever prints the film to tweak color balancing the way you want it. However, the 80A should get you close enough to make that task easier. The typical setup uses two lights on each side aimed at about 45 degrees to the image being copied. This is done to prevent glare. You might want to try doing this outdoors in open shade if you can set up there. Just be certain there is no glare from the surface of what you are copying. Look carefully for this; sometimes the glare is subtle. This does have the advantage of using daylight. Kodak has a special numbering scheme for entire series of CC (color correction) filters that you may see or hear about. They come in various colors: red, green, blue, magenta, cyan and yellow. There are various strengths of each color also. Often they are stacked for a very specific and highly accurate color balancing. This requires experiments to find the correct combination. Using these is complex and could get expensive buying a large number of filters. You may find a slight contrast increase between the original image and your copy. Not usually a problem unless the original has very high contrast. -- John
