If you were preparing to deliver a workshop on traditional film for photography for a fairly general audience of mostly amateur photographers, What 3 Topics would you be sure to cover?
Make-up of the audience is a big variable, as stated. But, all things being equal, I have actually been giving this a lot of thought. Besides this forum, I also participate on a state-based forum (in Texas) that is about half the size of APUG, but is 99% digital. However, whenever film is mentioned, an "old" camera (25 years :rolleyes

is discovered, or black and white comes up, there is always very positive response. What I have discovered is that the majority of these folks think that one CAN'T do film or darkroom anymore because the equipment and/or materials are not available. Afterall, there's no darkroom section at the Wolf/Ritz where they bought their gear!
So, I have been mulling around an idea for a workshop for B&W film. I wouldn't talk about composition, art, or even exposure; or anything that would be common to the digital shooters that would be my audience (some of which are full time professionals). What I would do is get some of these folks together to demonstrate to them that film is alive and well - and available!
I would develop a roll of film, and then make prints in a darkroom. Giving detailed instruction along the way, and always with hand-outs and references. This would be the the visual/activity part of the day, but have for them information on:
- where to get gear and supplies
- film formats and the advantages of each
- the costs necessary to set up a basic home darkroom
- costs/avalability/sources for the plethora of used, high quality gear
- products available (film, paper, chemistry, etc.)
- peer support (like us)
In other words, really "evangelize" (if you will) for film and analog processes. It would NOT be an A vs D speech. In fact, digital wouldn't even have to be mentioned - at least until someone in the group brought it up.
Oh, and besides the prints you make as a demo, show them some really high quality mounted fiber prints. One (good) picture is worth 1000 words ...
