Exposure guide at ISO 8#
Sunny 16 for this film: f/16 at 1/8 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 | 1/1250 s | 1/320 s | 1/80 s | 1/20 s |

| EV 13 · Cloudy-bright | 1/160 s | 1/40 s | 1/10 s | 0.4 s |
| EV 12 · Overcast / open shade | 1/80 s | 1/20 s | 1/5 s | 0.8 s |
| EV 10 · Sunset | 1/20 s | 1/5 s | 0.8 s | 3.2 s |
| EV 8 · Bright interior | 1/5 s | 0.8 s | 3.2 s | 13 s |

| EV 3 · City street at night | 6 s | 25 s | > 1 min | > 1 min |
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.
