Ok, I managed to view it larger with that method (seems that the web page
generator you're using puts pre-defined size parameters to the image tag).
Looks very nice to me. It looks like single coat casein prints I saw in the
unblinkingeye article...

As for paper white; since dmax is not so high with single coat and your
pigment load. Having some paper white (for specular highlights) will have
the effect of visually intensity the shadows. Maybe it's not the contrast of
your emulsion but staining (due to paper / sizing / pigment)... What is your
sizing method? What is the paper you're using? Do you clear your prints
later? (Potassium metabisulfite or sodium sulfite ect. Maybe we are seeing
some kind of sensitizer stain instead of paper white). Anyway, providing
this info will increase your chance of having useful advide from gum
experts. Again, the image looks nice - congratulations!

AFAIK, reds are not easy to work with (they block UV in a higher degree)...

Regards,
Loris.

Hi Loris,

I've uploaded a larger image. If you right-click and select view-image, a
larger image is loaded. I don't know why ...

As far as contrast is concerned..If there ain't no paper white in the image
(which there ain't) I don't really want to force the issue. Gum is in
essence a low contrast process is it not? If I decreased the potted Dich.,
the detail would be lost (with a longer exposure) or the entire image would
be lost (with the same exposure). Pictorialism is what really draws me to
gum. I have deliberately tried to emulate the master (Demachy) with the
choice of pigment etc..Vienna Red is not an easy pigment for me to work
with. It's something akin to ground up roof tiles and very opaque in the
mix. Maybe the gum experts can give me some guidance on the contrast issue..

Thanks and Best Regards

David
