Infrared-sensitive B&W. Reciprocity failure begins very early — above just 0.5s — so correction applies to nearly every long exposure. Use an IR/720nm filter for the infrared effect (meter accordingly).

Daylight-balanced C-41 colour negative. Correction begins above 1s using CineStill's published guideline (t^1.3). No published data sheet exists — bracket a stop or two on very long exposures, and err toward more exposure.

Aperture change → time multiplier
Full-stop ladder — each step is exactly 1 stop:
f/1.4 › f/2 › f/2.8 › f/4 › f/5.6 › f/8 › f/11 › f/16 › f/22 › f/32 › f/45
f/1.4 › f/2 › f/2.8 › f/4 › f/5.6 › f/8 › f/11 › f/16 › f/22 › f/32 › f/45
| Stop down | × time | Open up | × time |
|---|---|---|---|
| +⅓ | ×1.26 | −⅓ | ×0.794 |

| +1 | ×2 | −1 | ×0.5 |

| +2 | ×4 | −2 | ×0.25 |
| +2⅓ | ×5.04 | −2⅓ | ×0.198 |

Metered and shooting at the same aperture? Ignore this — read the tables as-is.
Otherwise: count the stops between the two apertures, multiply your metered time by the factor, then look up that row. Example: metered 5 s at f/8, shooting f/16 = +2 stops → ×4 → use the 20 s row.
Highlighted rows are whole stops; the others are the third-stop clicks in between.

Rows = your metered reading. Reciprocity-failure-adjusted column = actual exposure to set (no ND).
Blue = correction applied Grey = below film's threshold, no failure yet (= metered).
+ND columns add that filter on top. ND4=2 stops · ND8=3 · ND16=4 · ND4+8=5 · ND4+16=6 · ND8+16=7.
"—" = resulting exposure exceeds the shared 600 s display ceiling (or, for Provia 100F, its own 512 s manufacturer limit). This is a table-reading cap, not necessarily the stock's real safe limit — check the calculator's per-film note for stocks rated well beyond it.
Metered rows: 1–100 s (1 s steps), 100–200 s (5 s steps), 200–300 s (10 s steps), 300–600 s (20 s steps).
Aperture works exactly like an ND filter — it changes the time going in, never the correction itself. See the multiplier table above.
