Ilford Ortho Plus is a medium speed black and white negative orthochromatic film that is especially well-suited for continuous tone copy or reproduction work, as well as for half-tone, technical, and forensic applications. It has a nominal sensitivity of ISO 80/20° when exposed under daylight conditions, or ISO 40/17° when exposed under tungsten lighting, and can be developed in standard black and white chemistry. Additionally, since the film is only sensitive to blue and green light, it can be handled under red safelight conditions and developed by inspection for precise processing control. Its high-resolution, fine grain structure and long tonal range also make it ideal for producing faithful reproductions of original artworks and documents, as well as for photomicroscopy.
This item is one 36-exposure roll of 35mm film and comes in a cartridge that has been DX coded for ISO 80.

Ilford Ortho Plus 35mm Reviews
Sharp! Perfect for teaching! Develops normally.
Works under a red light. ( I used an Aperture MC pro set to RGB red 100% and taped over the screen ) Very cool to see it developing in realtime, and makes it far easier to demonstrate to others how to load the film onto reels in the complete darkness. I used Rodinal 1:25 for 7 minutes rotating back and forth, washed via dump and fill 10 times with water, then into Ilford Rapid fixer mixed 1:4 for 7 minutes rotating, then washed again and into kodak photo flow, squeegeed only by my fingers ( through nitrile gloves ) as I pulled it out of the solution.
I like contrast…
…and this film is contrasty. Very crisp and clean look. A nice change from my usual softer choice, Foma 200. Ortho 80 may become my go-to black & white film stock when I desire a not so much grainy look.
