How it works
One afternoon. Two prints in Prussian blue. You leave with both.
Herschel’s 1842 process: iron salts on paper, UV light, wash — the blue is Prussian blue.
Print one · shadowgram
1
Coat and dry
We coat the paper with iron salts. You watch how it goes on.
2
Arrange in light
Objects or shapes on the paper. Sun or UV does the rest.
3
Wash and dry
Rinse. Prussian blue settles. Your shadowgram is ready.
Print two · your picture
1
Send or bring a picture
Before the day, or at the start. We make the negative.
2
Expose and wash
Same process. Your image prints in that deep blue.
