Ilford Delta is a series of photographic films manufactured by Harman Technology Limited.

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

Its speed is only 1000/31° following the ISO methods, but it has a very wide exposure latitude.

[1] Delta 3200 was introduced in 1998, 10 years after Kodak's similar T-MAX P3200.

It replaced Ilford's high speed 'HPS' film.
