The Ilford Ortho Copy Plus Film is designed for studio photographers, copy specialists, and medical/forensic professionals seeking precise, continuous-tone reproduction. Its key benefit is the ability to achieve a range of contrasts, making it versatile for various copying tasks and specialized imaging. A primary consideration is its orthochromatic nature, meaning it is sensitive to blue and green light but not red, requiring appropriate lighting conditions.

Orthochromatic means the film is sensitive to blue and green light but not red light. This makes it ideal for copying tasks where precise color reproduction isn't critical but detail and tonal range are, and it allows for use with red safelights.
While it can be used, it's not ideal for general photography where accurate color rendition across the spectrum is desired. Its orthochromatic nature can lead to unnatural skin tones if used with standard lighting.
Contrast is primarily controlled through your choice of black and white developer, development time, and temperature. Ilford provides data sheets with recommendations for achieving various contrast grades.
Store unexposed film in its original packaging in a cool, dry place (10-20°C or 50-68°F) with moderate humidity (40-50% RH), away from radiation. Processed negatives should be stored similarly, protected from light and environmental extremes.
Yes, this is a black and white film. The negatives produced can be contact printed or enlarged onto standard black and white photographic paper.
The Daylight ISO (80) is for use with natural daylight or electronic flash, which has a blue-rich spectrum. The Tungsten ISO (40) is for use with incandescent lights, which are richer in red and yellow light, requiring a slower speed to compensate.
Adjust your development process. For higher contrast, consider a finer-grain, higher-acutance developer or a longer development time. For lower contrast, use a softer developer or a shorter development time. Ensure your lighting conditions are consistent.
While fine-grained, certain developers or aggressive processing can increase perceived grain. Try a different developer known for fine grain or slightly reduce agitation. Ensure accurate exposure.
This is likely due to incorrect safelight usage or exposure to stray light. Verify your safelight is indeed red and doesn't emit any blue or green light. Ensure complete darkness during loading and unloading.
Check camera light seals and ensure the film was handled properly in a completely dark environment. Inspect packaging for damage that could allow light entry before use.
Handling and Loading:
Handle Ilford Ortho Copy Plus film in a darkroom environment using appropriate safelight conditions. As an orthochromatic film, it is sensitive to blue and green light, and *not* red light. A standard red safelight is generally safe, but always test under your specific conditions.
Exposure:
Expose according to the ISO ratings: ISO 80/20° for Daylight and ISO 40/17° for Tungsten lighting. Adjust exposure based on your specific lighting and development process.
Processing:
This film can be developed in a variety of black and white developers. Contrast can be significantly influenced by the choice of developer, development time, and temperature. Consult Ilford's technical data sheets for recommended developers and processing parameters to achieve desired contrast levels.
Storage:
Store unexposed film in its original packaging in a cool, dry place, away from direct sunlight and sources of radiation. Recommended storage temperature is between 10-20°C (50-68°F) with a relative humidity of around 40-50%. Protect processed negatives from excessive heat, humidity, and light.
Compatibility:
This is a sheet film and is compatible with any camera or enlarger designed to accept 8x10" film holders.
