- I use a Nikon FM 35mm SLR with a 28-70 zoom lens, set on macro. For film, I
- use Kodak Gold 100, since it is readily available, fairly inexpensive, has
- good color, and is easily printed. Exposure times should be farily long to
- reduce the effect of screen refresh, but many films are not rated for more
- than 0.1 seconds of exposure. I guess at longer exposures, the color
- balances get out of whack. Anyway, Gold is rated up to 10 seconds of exposure,
- which is good enough for me. My camera's meter seems to work well enough for
- me; I usually shoot around 1/2 second and f/8, adjusting each for each shot.

- I've found that it is very helpful to find a sympathetic one-hour photo
- operator in your area. Most I've encountered are sick to death of out-of-
- focus snapshotss and really appreciate something different (like fractals).
- If you find a processer you can work with, then help them help you. The
- first exposure on every one of my rolls is a color standard. I use blocks
- of red, green, blue, cyan, magenta, yellow, white, and black. I have the
- processer set the balance for this first picture and leave it that way
- for the whole roll. Otherwise, you let the person printing decide what color
- your images should be. You may find that how a picture looks has as much
- to do with how it is printed as with how it was shot. Herein lies an
- advantage to shooting slide film.
