I'd love to see a workshop set up that would include a host of subject matter such as the zone system, filter usage (for color film) a more in-depth shop on LF shifts, tilts, swings, etc. The zone system I know a bit about...but not all. I use filters with b&W...but not much on color film, and for architecture, I mostly use the rise and fall of the front standard..but never touch the other controls.... and I think there are others out there that know a bit..but not all of these subjects. So, I'm thinking about one day to cover all these items and then go out and shoot late in the day. Any thoughts? ...or any other short topics?
