Purple Color 400 is a special effects color negative film that produces a unique effect when used in your Minox subminiature cameras. This film has been compared to color infrared film due to
the distinct colors in its images. Known for swapping greens with
purples, Purple Color 400 Spy Film produces landscape images that do have a
similar look to color infrared films.
Purple Color 400 is
meant to be cross-processed in C-41 chemistry and, when processed so,
the resulting film has an unnatural green base and extremely shifted
colors. As mentioned above, any green subject matter is rendered in
shades of purple to magenta, depending on the ISO the film is rated.
Beyond that initial color swapping, the rest of the image shows heavy
color casts. It makes this film both fun and fairly tricky to scan or
print.
