Dear List,
My apologies for the present mail adressed to Diana
Bloomfield whom I'm unable to reach by email.
Hi Diana,
So, here we are in april and I just wanted to give you a
few pointers in
order to be as economic as possible for your upcoming show.
When you mail me
your work I prefer to get it unmatted (as I have the
necessary equipment)
and I recommend to send it as "exhibition photographs
without commercial
value to be remailed to sender after exhibit". If you
state a commercial
value I will have to pay a proportional import tax.
I
can hang about 20 images in 30x40cm and 40x50cm frames.
Thank you for
showing your work at Atelier pH7 in the beautiful city of
Brussels.
Roger
Sorry again.

I use gelatin / dichromate to size papers. Works quite
well for me in a tri colour gum. I am not sure what is the procedure that
James has, so I can not comment on it. You have to remember that dichromates
are not the crosslinking agent. They have to be converted Cr (VI) from the
dichromate to Cr (III), by either dark reaction, which is slow, or UV
light. I coat with gelatin / dichromate , let dry and expose to sunlight for
15-30 minutes to harden the gelatin. I can email details if you want to try.
