EXPOSURE RATING

DELTA 400 Professional has a speed rating of ISO

400/27° (400ASA, 27DIN, EI 400/27) to

daylight. The ISO speed rating was measured

using ILFORD ID-11 developer at 20°C/68°F with

intermittent agitation in a spiral tank.

Best results will be obtained at normal contrast, but

good image quality will also be obtained at meter

settings from EI 200/24 to EI 3200/36.

It should be noted that the exposure index (EI)

range recommended for DELTA 400 Professional is

based on a practical evaluation of film speed and

is not based on foot speed, as is the ISO standard.

FILTER FACTORS

DELTA 400 Professional film can be used with all

types of filters (eg colour, polarising and neutral

density filters) in the usual way. Follow the

instructions given by the filter manufacturer.

The exposure increase in daylight may vary with

the angle of the sun and the time of day. In the

late afternoon or the winter months, when daylight

contains more red light, green and blue filters may

need slightly more exposure than usual.

Cameras with through-the-lens metering will usually

adjust the exposure automatically when using

filters. With some automatic exposure cameras, the

correction given for deep red and orange filters

can produce negatives under exposed by as much

as 1

2 stops.
