Character & history#

Infrared sensitive false color reversal film for IR photographic applications e.g. artistic, industrial, scientific, and aerial or technical ground photography. The extent infrared reflectance affects the final color rendition. E.I 200 (daylight), 100 (tungsten). (EIR)

Exposure guide at ISO 200#

Sunny 16 for this film: f/16 at 1/200 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.
