Cyanotype Magnification
Image Structure
The cyanotype image is made up of Prussian blue (ferric ferrocyanide) resting within the upper fibers of the paper support.

What to look for: Under low magnification the print appears to be continuous tone. Extremely high magnification would reveal individual image particles.
At 30x magnification paper fibers are clearly visible due to a lack of a binder layer. Image tone is continuous.

Layer Structure
Cyanotypes have a single layer structure. The sensitizer is coated directly onto the paper and the image forms within the upper fibers.

What to look for: The paper fibers are clearly visible. Prussian blue pigment rests within the top layer of the paper.
The ferric ferrocyanide image rests within the top paper fibers at the right.
Paper fibers are clearly visible at 50x magnification in raking light.
