How should I structure this film test roll?
Enter your frame count and frames per test condition to see the group structure and contact-sheet page count, a review layout, not a stock or development recommendation.

Evidence, not a pile of frames
A useful film test roll changes one documented variable at a time. The contact sheet then becomes evidence you can compare, not a pile of frames with forgotten conditions. This planner gives the roll a group structure and a proof layout while leaving stock, development, and aesthetic decisions to your actual process.
A 36-frame roll with three frames per condition gives 12 groups. A six-by-six contact grid holds the roll on one page; a four-by-three grid needs three pages. If you change both EI and development across one group, the comparison becomes confounded. Record frame ranges, stock, meter method, development, scan, and scene before you judge the results.
This is a planning calculation, not a certification. Confirm the relevant camera, lens, card, printer, contract, location, or workflow constraint in the real setup before relying on the result.
Compare the chosen crop and output at the intended physical size and viewing distance. A proof is more informative than a generic PPI or quality label because it includes the actual subject, processing, paper, and display context.
FAQ
- What should I test on my first roll?
- This tool does not choose settings. Start with one documented question and keep other variables as consistent as practical.
- Why no universal best setting?
- There is no universal best setting because the relevant tradeoff changes with the subject, light, movement, output, and the part of the image that matters. This tool makes the stated tradeoff visible rather than hiding it behind a generic recommendation.
