The photo 1 class that I teach (college level, but this might work with high school) is 2/3 analog b & w and 1/3 digital color. In the first class, which is two 3-hour sessions, I do a camera function lecture that includes my drawings of formats (you would laugh at the guy under a dark cloth using a large format & tripod!), d.o.f. and charts about the 1:2 relationship of f/stop, shutter speed, and ISO. Plus I project images showing these techniques by Robt. Frank, Thos. Struth, Nan Goldin, Chris Killip, Bill Burke others and I ask the students to guess what format was used, as well as general f/stop (open or close down?) and/or shutter speed (fast or slow?). The school has cameras that I can check out so that students can handle them as I speak, but I email them before the first class to bring an analog camera if they have one, and roll of Ilford HP5. Surprising how many have parents or grandparents who saved their old cameras!
In the afternoon, we go shoot together.In that way, they have at least 1 roll of film for the 2nd class, but should have 2 rolls based on an assignment I give. In addition, I have them practice loading used & exposed film onto reels, first with their eyes open, then with their eyes closed. So, they are ready to load and process in the next class.
I also teach non-silver classes (this summer at Photographer's Formulary and School of Boston Museum of Fine Arts). I get the students "dirty" in the first class, making photograms with the cheapest emulsion: cyanotypes. Again, I show images by Martha Madigan, Christian Marklay, Kunie Sugiura, etc. for inspiration.
