Presentation of the albumen print: the technique, the historical context and its applications.
Brief introduction and contact with historical material and albumen prints made by the collective.
Presentation of chemicals, medias (100% cotton paper without acid and transparencies for digital negatives) and safety regulations.
Description of the material: accessories used in the process.
Preparation of solutions necessary for the preparation and treatment of albumen paper: albumen solution, sensitive solution, gilding solution and fix preparation.
Coat the papers with albumen.
The coating of the papers will be done by suspension.
Drying hung from the albuminated paper and putting albuminated papers under pressure to reduce bending of the dried papers. We can proceed to a double coating for a brighter copies.

Scan the albumen print of the greyscale to create a curve in Photoshop.
We will create the curve automatically using a plugin that we will install in Photoshop and manually by visual analysis.
Apply the curve to the greyscale and make a copy again on albumen paper
Observe the print and find out that the curve improves the grayscale restitution. Adjust the curve if necessary.
Making albumen prints from digital negatives.
Apply the curve to the digital files and print the negatives on albumen paper.
Copy made by contact in a daylight chassis.
Treatment of albumen paper.
Observe and analyze the images obtained and identify the faults and their solutions
We will adjust the digital files until we obtain an albumen print that seems to us correct.
