Fuji Pro 160 redscale. Bronica SQ aI.
1/8 sec on tripod. shot at 100 asa.

Redscale is the name given to a technique of shooting photographic film where the film is exposed from the wrong side, i.e. the emulsion is exposed through the base of the film. Normally, this is done by winding the film upside-down into an empty film canister. The name "redscale" comes because there is a strong color shift to red due to the red-sensitive layer of the film being exposed first, rather than last [the red layer is normally the bottom layer in C-41 (color print) film]. All layers are sensitive to blue light, so normally the blue layer is on top, followed by a filter. In this technique, blue light exposes the layers containing red and green dyes, but the layer containing blue dye is left unexposed due to the filter. E-6 (color slide) film has also been used for this technique.
