Harman Photo film Switch Azure 125/36 — photographic negative film ISO 125, 36 exposures

Harman Photo film Switch Azure 125/36 is a colour negative film with ISO 125 sensitivity and 36 exposures per roll, designed for creative analogue photography. The emulsion produces deliberate colour shifts: blues render as orange, bright yellows shift to azure, and reds move toward purple-blue tones, producing surreal and playful colour effects while retaining fine grain and balanced tonality suitable for daylight and controlled lighting. The film is compatible with standard C41 chemical processing and intended for photographers who want predictable but striking cross-processed looks without complex workflow changes.

Advantages

Switch Azure offers distinctive colour-shifting characteristics in a moderate-speed, low-grain format that works well for landscapes, portraits and studio work. It maintains usable detail and smooth tonal transitions while producing unusual hues, allowing creative exploration without sacrificing the clarity associated with ISO 125 films. Compatibility with standard C41 labs keeps processing straightforward, and the film’s behaviour is sufficiently consistent for repeatable visual results when scanner and scanning settings are controlled.

Suitable for

• Creative colour experiments and cross-processed looks
• Outdoor landscapes and city scenes in daylight
• Portraits and environmental portraiture with controlled light
• Studio shoots where unique colour rendering is desired
• Photographers who process in standard C41 labs or scan negatives at home

Key specifications

• Film type: Colour negative film with intentional colour shift emulsion
• ISO sensitivity: 125
• Exposures per roll: 36
• Processing: Standard C41 development
• Grain and tonality: Fine grain with balanced tonal response

How to use

Load the 36-exposure roll into any compatible 35mm camera following normal film-loading procedures. Meter for ISO 125 in daylight or controlled lighting, or adjust exposure to taste for push/pull effects while keeping in mind that colour shifts remain a prominent characteristic. After exposure, send the film to a lab that performs C41 processing or develop it in a home C41 kit. When digitising, note that scanner type and settings significantly influence final colours; flatbed scanners or camera-based scanning often yield more neutral interpretations, while commercial lab scanners may produce stronger variations. Harman provides recommended scanning settings for popular systems to improve consistency.

Usage recommendations

For predictable Azure-style colour shifts, shoot in daylight or controlled artificial light and keep exposure close to ISO 125. If you scan negatives, test a few frames with your scanner or ask the lab for preview scans and adjust settings accordingly. For more neutral results, consider flatbed or mirrorless camera scanning; for more extreme colour variants, use common commercial lab scanning and experiment with the lab’s scan settings.
