Cross processing

As cross- development (also cross processing, X-Pro ) is defined as the reversal development of a color negative film, or vice versa, the negative development of a color positive film.

Here, the footage in its opposite development process, a color negative film, for example, instead of in the C- 41 in the E-6 process or transparency film, for example, rather than developed in E-6 in C-41 process. Characteristic of cross processed film are bright colors, high contrast, most coarse grain and often blur light. Is a cross development desired in a photo lab, so this must be explicitly specified. Depending on the film, the results may vary.

However, negative film, especially by his soft contrasts and the orange -colored carrier material, optimized for printing on real photographic paper, while slide film has a much lower latitude, as it is designed for direct projection. If a slide film cross - developed (in negative -Chemie), results in a very high-contrast negative on a clear substrate. Cross - development, especially slide film, is used by many photographers as a conscious stylistic device to get blue greenish- cool, slightly unreal paper prints.

You can basically be performed by any photo lab, developed the negative films. However, it is recommended that the laboratory to indicate explicitly that a cross-processing is desired, so that is not yet developed normally in the largely automated processes of the film. Many laboratories also fear adverse changes in the C-41 chemical approach by this unforeseen films and lead cross organizational developments therefore separate in time or regular development contracts through.

The Cross development can be simulated later in digital photography. Various digital filters can be applied in the camera or on the computer. By changing the hue and saturation curves with image editing programs like GIMP or Adobe Photoshop is such an effect can be produced. The strength of the effect may in this case be determined by the processor targeted.
