Exposure guide at ISO 160#
Sunny 16 for this film: f/16 at 1/160 s in bright sun. Negative film tolerates 2–3 stops of overexposure; slide film needs accuracy within about ⅓–½ stop.
| Light | f/2 | f/4 | f/8 | f/16 |
|---|---|---|---|---|
| EV 16 · Snow / beach, bright sun | — | — | 1/1600 s | 1/400 s |
| EV 15 · Bright sun | — | 1/3200 s | 1/800 s | 1/200 s |
| EV 14 · Hazy sun | — | 1/1600 s | 1/400 s | 1/100 s |
| EV 13 · Cloudy-bright | 1/3200 s | 1/800 s | 1/200 s | 1/50 s |
| EV 12 · Overcast / open shade | 1/1600 s | 1/400 s | 1/100 s | 1/25 s |
| EV 10 · Sunset | 1/400 s | 1/100 s | 1/25 s | 1/6 s |
| EV 8 · Bright interior | 1/100 s | 1/25 s | 1/6 s | 0.6 s |
| EV 5 · Home interior at night | 1/13 s | 0.3 s | 1.3 s | 5 s |
| EV 3 · City street at night | 0.3 s | 1.3 s | 5 s | 20 s |
Push & pull options#
Tell your lab how many stops you pushed or pulled so development is adjusted for the whole roll.
| Adjustment | Rate the film at | Effect |
|---|---|---|
| Pull 1 stop | EI 80 | Lower contrast, finer grain |
| Push 1 stop | EI 320 | More contrast and grain |
| Push 2 stops | EI 640 | Strong contrast, coarse grain, blocked shadows |
| Push 3 stops | EI 1,280 | Strong contrast, coarse grain, blocked shadows |
Long exposures#
Most films suffer reciprocity failure beyond about 1 second: they need more exposure than the meter says. As a rule of thumb add ⅓–1 stop for 1–10 s and 1–2 stops beyond 10 s for older emulsions; modern T-grain films (and Fuji Acros) need much less. Check the manufacturer's datasheet.
