Everything about Anthotype totally explained
An
Anthotype is a
image created using
photosensitive material from
plants. This process was originally invented by
Sir John Herschel in
1842. An
emulsion is made from crushed flower petals or any other light-sensitive plant, fruit or vegetable. A coated sheet of paper is then dried, exposed to direct full sun-light until the image is bleached out.
History
The photo-sensitive properties of plants and vegetables have been known to scholars for centuries. Among many early observations the experiments of
Henri August Vogel in
Paris are of particular interest. He found in 1816:
An alcoholic
tincture of either red
carnations,
violets or
corn poppy turned white behind blue glass in a few days, while it remained unchanged behind red glass after about the same time. Cotton and paper colored with these tinctures showed the same differences.
When Herschel later that century attempted to invent a color process, he tried several flower and plant emulsions and published his findings. His research resulted in what we now refer to as the anthotype process. It should be pointed out that his research into making photographic images from flowers was limited and was ultimately abandoned since no commercial application was feasible from a process which takes days to produce an image. The process continued to be listed in photographic the literature of the time but was likely little used.
Over time the process has earned a false reputation for being simply too impractical. Image permanence have been brought into question to this day but this problem seems to be mostly related to choice of flower or plant matter.

Other flower suggestions
Henry H. Snelling writes based on his research: "
Viola Odorata--or sweet scented violet, yields to alcohol a rich blue color, which it imparts in high perfection to paper.
Senecio Splendens--or double purple
groundsel, yields a beautiful color to paper."
