P-F is Post Factory Photography a very good publication by the list's own
Judy ( jseigel@panix.com ). It comes out about 4 times a year and is full
of great advice for the alt photo crowd.

Reversal is a development process that "reverses" the image you would
normally get. One of the problems with making enlarged negs is that most
folks start with a negative. If you enlarge this onto film you get a
positive. This positive then has to be enlarged or contact printed a second
time onto a second sheet of film to get the negative required for most
processes. Reversal processing makes a negative in one step.
