• Sourced from medical X-ray film and adapted to standard perforated 35mm film for your still photography camera
• diffusion effect and beautiful, enhanced grain into every photo due to the lack of anti-halation layer
• Variable ISO - shoot between 200 – 400 ISO - Our tests indicate that 200 ISO is the “sweet spot”
• An Orthochromatic (ortho) film. Ortho films can only see blue and green (outdoor) light. Reds are rendered darker and therefore create darker skin tones. 
• Our X-ray film has a higher green sensitivity, enabling the film to be handled using a red photographic safe-light and allows processing by inspection, meaning you can load and unload film onto your home development reels when using the safe-light

This is how they advertise this film.  I thought it was a nice BW film.  I developed it in Ordinal 1:50 for 11 minutes ( 10-12 is what they recommend). I didn’t see it as being super contrasty and grain was not a problem.  I only had a few weird shots that I can’t explain:

The rest were fine:
