Ilford Delta is a series of photographic films manufactured by Harman Technology Limited. Delta films are tabular-grain black-and-white films, [2] and originally released in 400 ISO only to compete with Kodak's T-Max film.[3]

Ilford recommends Delta 100 and 400 as replacements for the discontinued Agfa APX100 and APX400 films, respectively.[4] Delta 100 can be used at ISO speeds of 50 to 200.[5]

Delta 3200

The 'Delta 3200' product is not actually rated at ISO 3200/36°. Its speed is only 1000/31° following the ISO methods, but it has a very wide exposure latitude. Thus it can be successfully push processed to EI 3200 or 6400, or even 12500.[1] 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.

gollark: You shouldn't have definitions of things be "whatever is politically convenient for me" and shouldn't just do a strategic equivocation/motte-and-bailey thing by switching them out constantly.

gollark: Precise definitions are important! It is a sexual orientation, by the second one!

gollark: If you make it "a mapping of characteristics to preference", then it is.

gollark: I mean, if you require "sexual orientations" to be "a mapping of gender to preference" or something, then no it isn't.

gollark: Technically, it is.
