Re: ortho film

I have used this film in the past when found at surplus stores. There is
mention of it in my Compact Photo Lab Index from 1979. It has an ISO of
50 under tungsten light. It is able to record intermediate tones like
handwriting or the lines of an etching. Their recommendations for
developing are only for high contrast results, though they list one of
the developers to be HC110 dilution B for 5 min at 68F/20C as being high
contrast. I remember using dektol very diluted to make semi continuos
tone negs for alternative process printing. You might try Clayton's
Extend Plus from Freestyle. Its a single solution low contras developer
made to make low contrast results from high contrast materials.
