The Ilford Delta 100 Professional is a black and white film. It was introduced in 1992.
Its sensitivity is specified as ISO 100. However, the flat crystal film can also be pulled or pushed to ISO 50 and ISO 200. Ilford itself calls it the best in its class. It is said to deliver fine grain and a high level of sharpness.
Developing the Ilford Delta 100
The Ilford Delta 100 needs to be processed in a standard black and white developer. This does not necessarily require the chemistry from Ilford itself. Developed the film can be either by a self in the home laboratory or in the specialized laboratory of his confidence. With the appropriate developers, it is also possible to develop the film as a reversal film to obtain monochrome slides.
There are several black and white developers, including Rodinal, D-76, XTOL, ID-11, or Ilfosol 3, that can be used to develop film. The choice of developer can have a significant impact on the final result. If specific development specifications for a developer are not available for the Delta 100, this requires an experimental approach to find the optimal developer.
After development is complete, film strips containing the captured images remain. This is usually followed by the production of prints or digitization. In many photo labs, it is possible to make prints of the images. To process the images in digital form, it is necessary to digitize the film strip with a scanner. There is a wide range of scanners for digitizing negatives, from simple scanners to specialized devices. After digitization, the images can be shared in different formats on different platforms or obtained in printed form.
Formats
The Ilford Delta 100 is available as 35mm film, medium format film and flat film (9x12cm, 4x5", 5x7", 8x10"). The cartridges of the 35mm film are DX encoded. The unexposed film should be stored in a dark and cool place.
In addition to it, there are the Delta 400 and the Delta 3200.

Sample photos
The pictures were taken with the Olympus OM 2 and an expired Delta 400. Developed the black and white film in Rodinal and digitized with a Canoscan 9000F flatbed scanner (eBay / Amazon*).
