Exposure guide at ISO 100#

Sunny 16 for this film: f/16 at 1/100 s in bright sun. Negative film tolerates 2–3 stops of overexposure; slide film needs accuracy within about ⅓–½ stop.

Developing E-6: Colour reversal (slide) chemistry. Fewer labs run E-6 today; it can be cross-processed in C-41 for saturated, contrasty colours.

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.
