Character & history#
Traditional black and white film with fine grain, moderate contrast and deep tonal range. *EI of 80, can also be shot at 100 ISO. Supplied in the same formats as Shanghai GP3, CatLABS confirmed that the roll films are converted by Shanghai after GP3 branded tape was found on rolls.

Exposure guide at ISO 80#
Sunny 16 for this film: f/16 at 1/80 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 | — | 1/3200 s | 1/800 s | 1/200 s |
| EV 15 · Bright sun | — | 1/1600 s | 1/400 s | 1/100 s |
| EV 14 · Hazy sun | 1/3200 s | 1/800 s | 1/200 s | 1/50 s |
| EV 13 · Cloudy-bright | 1/1600 s | 1/400 s | 1/100 s | 1/25 s |
| EV 12 · Overcast / open shade | 1/800 s | 1/200 s | 1/50 s | 1/13 s |
| EV 10 · Sunset | 1/200 s | 1/50 s | 1/13 s | 0.3 s |
| EV 8 · Bright interior | 1/50 s | 1/13 s | 0.3 s | 1.3 s |
| EV 5 · Home interior at night | 1/6 s | 0.6 s | 2.5 s | 10 s |
| EV 3 · City street at night | 0.6 s | 2.5 s | 10 s | 30 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 40 | Lower contrast, finer grain |
| Push 1 stop | EI 160 | More contrast and grain |
| Push 2 stops | EI 320 | Strong contrast, coarse grain, blocked shadows |
| Push 3 stops | EI 640 | 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.
