Ilford Delta 400 Professional
Medium format black and white film with medium high sensitivity of 400 ASA – 27 DIN.
Designed for photography in medium or difficult lighting conditions. It was made with special technology to control crystal growth – same size and shape. Delta has medium contrast, low grain, high image sharpness is delicate and subtle in drawing. It can be easily forked to sensitivities of 800 and 1600. Of course, the less light, the worse the effect of forking will be. Forcing the negative exposed in contrasting conditions significantly increases the contrast of the resulting image.
To make the most of the film’s advantages, it is recommended to develop it in developers designed for T-crystal films, including Ilford DD-X, Kodak T-max, Paterson FX 39 and Tetenal Ultrafin-T Plus. The film can also be developed in other commonly used developers, although some of them may give larger grain, which is not visible at medium format enlargements anyway.
The number of frames taken depends on the type of camera: from 15 in 6×4.5cm format, 12 frames 6x6cm, 8 frames 6x7cm to 6 pieces in 6x12cm panorama format.
Ideal for art photography, product photography and many areas of creative photography where low sensitivity films were previously used. Ilford’s Delta 400 film has a bright protective paper on the outside. The black numbers on a white background indicating the number of the exposed frame are easily visible in cameras like Diana, Ami, Druch, Holga, etc., which have a red window for viewing the frame number. In the case of professional cameras, where there is no preview of the sliding tape, it does not matter: Hasselblad, Mamyia, Bronica….
