Kodak Ektachrome Dyna EX 100

The Kodak Ektachrome Dyna EX 100 is a slide film that was sold as part of the Kodak Ektachrome Dyna EX film family and the Kodak Select Series, primarily in Asia and especially in Japan. This is probably relabeled film material that was marketed in the West under a different name. There are no new productions of this film today. Nevertheless, the Ektachrome Dyna EX 100 enjoys a certain level of popularity among film enthusiasts.

With a light sensitivity of ISO 100, the film is aimed at photographers who appreciate a classic color look with fine grain. Since it is a standard film, it does not deliver exceptional results, but its results are impressive thanks to solid color reproduction and a good contrast ratio, typical of Kodak products of that time.

Development in the E6 process

The Kodak Ektachrome Dyna EX 100 is developed in the E6 process, a standardized process for color slide films. This process makes it possible to preserve the characteristic, brilliant colors and the typical sharpness of a slide film. Many photo labs continue to offer the E6 service, which makes it possible to use the film even today. After development, the slides can be viewed on a projector or digitized with a scanner in order to integrate them into modern image processing or archiving.

Availability and alternatives

The Ektachrome Dyna EX 100 was only available in 35 mm format, with a film roll that offered space for 36 shots. Equipped with a DX code, cameras with automatic ISO detection could easily adjust the film speed. Suitable camera models for this film were produced by manufacturers such as Agfa, Olympus and Zenit.

Since the film is no longer manufactured, the only hope is to find old, unused rolls. An alternative is the Kodak Ektachrome E100G *, which also specializes in color slides, is still in production and has similar properties.

Storage and shelf life

Since the Ektachrome Dyna EX 100 has long since been discontinued, most of the remaining film rolls are probably past their expiration date. This date indicates how long the original quality is guaranteed, but has no direct influence on whether the film can still be used. Older films can, however, show a drop in light sensitivity or color shifts.

To maintain quality, cool and dry storage is essential. Unexposed films should be kept in the refrigerator, for example. Films that have already been exposed, on the other hand, should be developed promptly to minimize possible loss of quality. Photographers can adjust older films by making a correction on the light meter by slightly reducing the ISO setting to compensate for the loss of sensitivity.
