Reply #3: Slide film or transparency film is basically the same as movie film.

Instead of a negative, you get a positive image on the orginal film which can be viewed directly or projected, without being printed on paper. The advantage is that What You Shot Is What You See, in contrast to prints made from negatives, which can vary greatly. As a learning tool, it lets you see what your camera recorded. The downside is that getting slide film processed is a bit more trouble and you need a projector to see the results.

(edit to add) If you don't already have a projector, I wouldn't recommend using slide film and buying one just for this purpose. Use that $$$ for getting your film negatives images digitized for posting here.
