Hard Cut 25 is hand-spooled from Eastman Kodak High Contrast Positive Film II 5363. Before digital compositing, specialized laboratory stocks helped create the lettering, silhouettes, and traveling mattes used in motion pictures. Kodak designed 5363 for these optical-printing tasks, where clean edges and dense blacks mattered more than a gentle tonal scale. Its companion 16mm stock was numbered 7363. [1]
Kodak’s March 1999 technical sheet documents a blue-sensitive emulsion on clear acetate safety base, with an antihalation undercoat and a lubricated antistatic backing. Developed in D-97 for its intended laboratory use, the specified control gamma was 2.90–3.20: deliberately extreme contrast. [1] AIF gives this specialist stock a new role in still photography, hand-rolling it from a recovered 2,000-foot master roll.
A Different Way of Seeing
Blue-sensitive is not the same as panchromatic—or even conventional orthochromatic film. Expect blues to reproduce relatively light and reds and other warm colors relatively dark. Exact rendering depends on illumination and the subject’s spectrum. Daylight and flash are useful starting points; warm tungsten light may need much more exposure. Kodak did not assign a still-camera ISO rating: the EI values below are practical exposure indices, not manufacturer ISO speeds.
Development Times
Times are shown as minutes:seconds, not decimal minutes. The bold 20°C / 68°F column contains the published reference times. Ordinary negative development produces negatives, despite the stock’s original “positive film” name.

Agitation, dilution and processing guidance
Unspecified agitation: Where the source gives no schedule, follow your developer maker’s small-tank instructions as a test protocol. The source recipe is incomplete; AIF does not claim a verified agitation schedule for those rows.
Dilution notation: 1+1 means one part prepared stock developer plus one part water. HC-110 ratios are from concentrate, not a separately diluted stock. Follow the bottle’s formulation and minimum concentrate-per-roll requirements; high dilution can exhaust developer in a small tank.
After development: Use a compatible stop bath or water rinse, black-and-white fixer according to its instructions, a thorough wash, and wetting agent. Do not use a color bleach bath. Keep bath temperatures reasonably close. Load in total darkness unless using a properly tested Kodak-specified safelight arrangement.
Original Process & Recipes Awaiting Testing
| Developer | Status | Time / Temperature | What to Know |
|---|---|---|---|
| Kodak D-97 | Manufacturer process | Time requires calibration. 21°C / 70°F in Kodak’s test curves. | The original title/matte process. Kodak shows 2, 3½, 6 and 8 min curve examples—not four interchangeable still-camera recipes. Its control-gamma target is 2.90–3.20. Start with step-wedge tests, not an important roll. [1] |
| D-96 | Untimed option | No verified 5363 time included. | Candidate for comparative testing; this page does not promise lower contrast or effective speed for this batch. |
| Rodinal / R09 | Untimed option | No verified 5363 time included. | Do not assume a generic “1+100 for one hour” recipe is established for this film. |
| ID-11 | Transfer test needed | No independently verified time included. | Often used similarly to D-76, but the D-76 entry above is not an AIF-tested ID-11 recipe. |
A first-hand FPP report describes 5363 exposed at EI 25 and developed in D-76 1+1 for 12 minutes, with strong contrast. Temperature and agitation are not specified in that article, so it is useful context—not a complete temperature-calibrated recipe. [4]
Stand & Semi-Stand Development
Dilute, reduced-agitation development is worth testing to restrain contrast, but it cannot restore spectral sensitivity or guarantee a normal tonal scale. It can also produce uneven development and streaking near the perforations. The timed HC-110 G recipe above uses periodic inversions; do not silently substitute a single midpoint agitation. Full-stand and midpoint-only semi-stand times will be added only after documented testing.
Shooting & Testing Notes
- Start around EI 25 in daylight. Bracket EI 12, 25 and 50 to establish your own shadow exposure.
- A light meter is not blue-sensitive. Equal meter readings under daylight and warm lamps may not produce equal film density.
- Avoid red, orange and yellow filters for initial tests. They can remove the wavelengths this film needs. A green filter may also severely reduce exposure.
- Separate exposure from development. Test repeated scenes or a step wedge; keep scanning adjustments consistent when comparing contrast.
- Record the whole recipe. EI, light source, dilution, working volume, temperature, time, agitation and chemistry usage are all needed for an AIF-tested entry.
