San Mateo Coast, Redscale

I loaded Kodak Portra 400 220 film (no paper backing) in my Fuji GSW 690III backwards so the back of the film was facing the lens for redscale. Medium and large format film bases are thicker than 35mm and you have to compensate even more, so I metered this 400 ISO film at 25 ISO. Even so, many of the exposures are thin.
