Anna Atkins cyanotype
This is a piece of work by someone named Anna Atkins. this is a cyanotype of what looks like leafs. This is a cyanotype as the image is made by chemicals and then it is left in the sun and then it will give you the image above.This is what people would use to document things back when they didn't have the camera. This is not the best way to document images and things as it does not have that much detail as it is just the outline of the object.
