Redscale Exposure – Part 2
A few feet down from the building shown in redscale yesterday, I also shot this building but with an over-exposure of two stops. The resulting effect is what is typically expected. The bright color of the subject also allows details to be more visible.
The reason for the dominating red hues and the need for over-exposure in the majority of circumstances is related to the way the film is exposed to the light. To create the redscale effect, the film is loaded backward in the canister in order to invert the order in which layers of color are exposed to light when a picture is shot. The red layer gets the most exposure but because the film is flipped backward, the acetate base is now in front instead of the back of the film, resulting in less light going through the film.
