We have found several simple photographic techniques to be helpful in preparing our own near-professional teaching slides. Effective use of different brands of photographic materials is possible, but we present only the ones with which we are most familiar and which we have found simple, economical, and reliable. Slides can be produced in less than 24 hours using the methods presented.
