Harman-Kardon film accessory RED 125/36 model 1182318

HARMAN RED 125 is an ISO 125 redscale colour negative film based on the HARMAN Phoenix emulsion. Shooting redscale means the film is exposed through the base so the red-sensitive layer is recorded first, producing images dominated by reds, oranges and yellows. The film comes in a DX-coded 35 mm cassette with edge markings and is processed using standard C-41 chemistry. It has a box speed of ISO 125 and a usable exposure index range of EI 50–400; recommended working range is EI 100–200 depending on scene brightness and contrast.

Advantages

HARMAN RED 125 offers a clear film base and high sensitivity to red light, delivering distinctive redscale colour rendering. Its medium ISO 125 speed provides a balance between fine grain and exposure latitude, while the DX-coded cassette and standard C-41 processing make it compatible with common lab workflows. The film produces a wide variety of tonal results—from intense apocalyptic oranges and deep reds to more subdued orange-green shifts—depending on exposure choices and scene characteristics.

Suitable for

• Creative photography where strong red/orange/yellow colour casts are desired
• Portraits and landscapes reinterpreted with redscale tones
• Experimental and artistic projects exploring alternative film effects
• Photographers who process or send film for standard C-41 development

Key specifications

• Film type: Colour negative, redscale (35 mm)
• Emulsion: HARMAN Phoenix
• ISO / box speed: 125
• Usable exposure index (EI): 50–400; recommended EI 100–200
• Cassette: DX coded, edge marked
• Processing: Standard C-41

How to use

Load the DX-coded 35 mm cassette into your camera and set the exposure index according to desired tonal effect—EI 100–200 for best general results. Compose and expose as usual; redscale renders the red-sensitive layer first, so expect colour shifts toward reds, oranges and yellows. After shooting, process the film using standard C-41 chemistry at a capable lab or in home C-41 developing equipment. Handle negatives and scans knowing colours will vary with exposure and development.

Usage recommendations

Underexpose to emphasize coarser grain, prominent shadows and deeper reds; normal exposure yields consistent orange tones and softer shadows; overexpose for finer grain, brighter contrast and a wider range of tones. For predictable results, test at EI 100 and EI 200 with scenes of different brightness and contrast.
