ILFORD ORTHO Plus black and white copy film is designed for many applications. It is particularly recommended for continuous tone copy work, with no sacrifice in quality when the original includes line work. The blue and green sensitivity enables the film to be handled in red safelight and allows processing by inspection. This versatile film allows you to fine-tune the contrast by the choice of developer, the exposure given and the development time. It is possible to achieve an accurate reproduction of most black and white originals, or to maintain a clean background in copies of combined line and continuous tone originals.
The characteristic curve of ORTHO Plus copy film has been optimised to ensure the tonal range of the original image is maintained. This is different to conventional films, which can give a dull, flat result when used for copying. The qualities of a high resolution film with precise contrast control is just what is needed for photomicroscopy. ORTHO Plus copy film is highly recommended for this application.
ORTHO Plus copy film is coated on 0 180mm/ 7-mil polyester base, well known for its high dimensional stability and strength. The film is protected by an efficient anti-halation backing which clears during development. If processed and stored properly, ORTHO Plus copy film has excellent archival storage properties.

I have been using this film for about a year. I use it in 4x5 film holders in a Lensless Camera Co, pinhole camera. With slow speed film (ASA80) and very small aperture f/232), daylight winter time exposure is about 75 seconds, summertime about 25-45 seconds. This film gives a very wide range of gray scale: plus or minus about two full stops. The tonal quality over the range is uniform. At the lower contrast range the image is a bit thin and requires spotting. At the high range of scale the density usually does not require spotting. I handle and develop under Red safe light. I develop using Ilford IL-11 (17-18 min), Kodak Short Stop (quick dip), Ilford Quick Fixer (5-8 min). While wet the emulsion is very soft and requires care not to touch. When dry you can handle easily. The film has extremely fine grain. I use it for both portrait, nature, ghosts (objects in motion), and architecture.
For those of us who still like to work with a negative, or believe we can get better quality with one, and want to copy images--historical or otherwise--this is the film to use. Many of us lamented the loss of Kodak's Professional Copy film. Ilford's Ortho Plus is as good, perhaps even better for copying photographs. And it's relatively easy to work with, and results are consistent.
