Exposure guide at ISO 800#

Sunny 16 for this film: f/16 at 1/800 s in bright sun. Negative film tolerates 2–3 stops of overexposure; slide film needs accuracy within about ⅓–½ stop.

Push & pull options#

Tell your lab how many stops you pushed or pulled so development is adjusted for the whole roll.

Pull 1 stopEI 400Lower contrast, finer grain
Push 1 stopEI 1,600More contrast and grain
Push 2 stopsEI 3,200Strong contrast, coarse grain, blocked shadows

Developing C-41: Standard colour-negative chemistry available at almost every lab and in home kits (Tetenal/Cinestill Cs41).

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.
