For the most part the workshop participants took the shots with them.
We used regular paper developer. It's the Multigrade liquid 1:9. They mention ways to control the contrast on the Harman site. Pre-flashing seems to work. In the studio I have control over the contrast.
I would image a softer developer would work as well.
ISO 3 worked well, no filters on shooting lens.
Don't be put off by the thickness, it's workable, it was just a surprise. You can still make it work with a regular holder.
I'll play with it for bit next week, and if I get a nice shot I'll post one.
If I don't get a nice shot I'll read the instructions.
