So I came across this process in some anecdotes recently, and was thinking of doing a project where the final prints would be anthotypes. I have not been able to find much technical information, if any, on how to make them. To the best of my understanding it involves some extract of pigmented plant tissues or an emulsion of some sort-- which implies to me that it would be applied to the surface of the paper. Does anyone have any resources for which plants to use and how to extract the pigment/coat paper? Really anything at all would be appreciated! Thanks
