I once produced some gum photographs of vegetables that utilized pigments
that I extracted from the actual subject matter. They pretty much faded.
Here is an example of one of them, a beet that at one time was a rich
beet-red: http://www.gumphoto.com/Vegetables/images/22.jpg
I've been toying with the idea of using flowers. What is the lasting-power
of those anthotypes?

I'm very interested in this discussion of viable pigments.
How about natural sources? There are many natural dyes and techniques
for coloring everything under the sun, from paper to wood. I got lost in
the myriad of information available on the WWW for stains, dyes,
mordants, and agents of changing colors... I was just looking for a
cheapo source for tannic acid, but I got a huge education(?).
Also, I've been trying the anthotype process lately and my roses produce
a beautiful violet-magenta color and an image in just about three days.
I should try to produce a gum print with some of my pigment slurry. Ah,
so little time so many experiments.
