UK-based company Harman Technology has recently expanded its line of color negative films with the release of Harman Red 125 in 120 format, following its initial launch in 35mm earlier this year. Harman Red 125 is a redscale film rated at ISO 125 and developed using the standard C-41 process. It is derived from the Harman Phoenix 200 emulsion and utilizes the film base’s red-sensitive layer to create a distinctive color shift by reversing the typical orientation of the film during exposure.

When exposed through the base layer, the film produces varying tones of red, orange, yellow and occasionally green, depending on lighting conditions and exposure. According to Harman, high exposure levels result in finer grain and brighter tones, while lower exposures emphasize shadows, coarser grain and green highlights. While nominally rated at ISO 125, the film has a usable range between ISO 50 and 400, but best results are typically achieved within the ISO 100 to 200 range.

Harman Red 125 is designed for photographers interested in experimental processes and those comfortable with the unpredictable tonal variations typical of redscale photography. The absence of an anti-halation layer in the emulsion enhances halation effects, contributing to the film’s distinct aesthetic: high-contrast images with visible grain and unpredictable but often dramatic color shifts, depending on exposure and ambient lighting.
