Delta is a tabular-grain black-and-white film from Ilford Photo.^[1].

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 even higher. Delta 3200 was introduced in 1998, 10 years after Kodak's similar Tmax p3200. It replaced Ilford's high speed 'HPS' film.

Delta 400 can also be pushed to EI 3200.

Ilford recommends Delta 100 and 400 as replacements for the discontinued Agfa APX100 and APX400 films, respectively.^[2]
