Couples at the students of the VSHDIA are very interesting: yesterday we removed for you the MK from a guest speaker on cyanotopy.
Cyanotypy is a method of printing photographs originating in 1842, a silverless photographic process that gives a blue tint when photographic printing.
The process has many nuances, ranging from the chemical composition and ratio of reagents, and ending with the time of illumination.
The guys tried the ancient method of printing, with their own hands making photos of eminent masters of photo art and showing silhouettes of flowers and dried flowers by the method of Anna Atkins (XVIII century).
