Character & history#
Agfacolor Neu, also known as Agfacolor 111, went on public sale in November 1936 in 135 format as an ISO 3/6° film and was the first subtractive 3 layer color film incorporating dye couplers in each of the layers which could be processed at the same time by a single color developer. This arrangement formed the basis for all subsequent color slide and negative films. In comparison, Kodak Kodachrome which launched a year earlier required the processing of each color layer separately.

Exposure guide at ISO 3#
Sunny 16 for this film: f/16 at 0.3 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 | 1/500 s | 1/125 s | 1/30 s | 1/8 s |
| EV 15 · Bright sun | 1/250 s | 1/60 s | 1/15 s | 1/4 s |
| EV 14 · Hazy sun | 1/125 s | 1/30 s | 1/8 s | 0.5 s |
| EV 13 · Cloudy-bright | 1/60 s | 1/15 s | 1/4 s | 1 s |
| EV 12 · Overcast / open shade | 1/30 s | 1/8 s | 0.5 s | 2 s |
| EV 10 · Sunset | 1/8 s | 0.5 s | 2 s | 8 s |
| EV 8 · Bright interior | 0.5 s | 2 s | 8 s | 30 s |

| EV 3 · City street at night | 15 s | > 1 min | > 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.
