Yes, that's about right. The "Fresson look alikes" are monochrome prints
with a granular appearance.The full colour Heliochrome prints are
continuous tone with bright, rich colours and with tremendous subtlety too!
The image of the still life of the fruit was stunning. I could almost reach
out and touch that apple.

I am not sure whether or not he is printing the "Fresson" type prints for
clients but he is definitley printing the colour Heliochromes for several
"big name" advertising photographers.

The prints that I saw were printed on Bockinford Not Watercolour paper
although there were a couple of prints for one particular client printed on
Fabriano Artistico and they had that fine canvas look about them. I suspect
that he would be prepared to print on any suitable paper but I assume that
he has calibrated his process for Bockingford and that he may charge more
for other substrates. The surface of the papers had a surface sheen on the
borders and had obviously been surface sized with a polymer? prior to the
colour coatings.

The colorant? Well my guess is as good as yours! He wasn't giving anything
away apart from the fact that the prints were machine coated.....no brush
marks here! If you twisted my arm I would guess that the colourant was an
acrylic based polymer.
