Ilford Delta is a series of photographic films manufactured by Harman Technology Limited. Delta films are tabular-grain black-and-white films.[2]

Ilford recommends Delta 100 and 400 as replacements for the discontinued Agfa APX100 and APX400 films, respectively.[3] Delta 100 can be used at ISO speeds of 50 to 200.[4]

Delta 3200

The 'Delta 3200' product is not actually rated at ISO 3200/36°. Its speed is only ISO 1000/31° but it has a very wide exposure latitude. Thus it can be successfully push processed to EI 3200 or 6400.[5] Delta 3200 was introduced in 1998, 10 years after Kodak's similar T-MAX P3200. It replaced Ilford's high speed 'HPS' film.

Delta 400

Delta 400 can also be pushed to EI 3200.
