I do shoot as mentioned B/W and C41 color film (B/W mostly) and do develop at home.
Caffenol-C-L for most films, and if I have films that didn't like Cafenol-C-L (most Rollei films) I'll use Ilford Ilfosol 3
For C41 color I use Cinestill Cs41.
Don't have an enlarger so I have a hybrid setup (Plustek Opticfilm 8200i) and scan the negatives I want to use.
Whenever I do a portfolio set its usually around 300 to 400 photos and then I only usually keep about 100 to 150 for a set. How much would 10 of the 36 films have cost before digital?
Depended on the decade. In the 1970s, $4-5 for a roll of slide film. Much more for prints from negative film. The prices went up quite a bit in the 80s and 90s.
