Thirty-Six - plan a roll of film as a contact sheet

thirty-six.skillsafe.ai

Clean

Plan a roll of film before you load it: list the shots for an outing and see them as a contact sheet - which frames your film speed and point-and-shoot, single-use or manual camera can expose, which need the flash, which come out too dark, and what will not fit on 24, 27 or 36 exposures (exposure numbers are estimates from rules of thumb). Free: the planner, the sheet, Markdown/CSV/JSON/SVG exports. Paid: a film-photo critic calls the roll ready, rebalance or wrong film, re-allocates the frames and writes a composition note per group. Built on the SkillSafe skill @curiositech/photo-composition-critic.
