One Roll of Harman Switch Azure 125 – 35mm Creative Colour-Shifted Negative Film ISO 125/22° in C-41 Process DX-Coded Film Canister Harman Switch Azure 125 has its colour couplers deliberately swapped around, so blue light lands in the red channel and red lands in the blue. Blues come out orange, yellows go a vivid azure, and reds shift through purple. It shoots best outdoors at box speed, metered for the mid-tones, with a bit of bracketing when the light is harsh. There is no orange mask on this one, so your negatives will dry with a purple cast, which is completely normal. It runs through standard C-41 alongside everything else, so just mention it’s Azure when you send it in and we will scan it to keep the colour shift rather than neutralise it out.
