Tamamura's art, hand-colored in the chicken albumen paper style.

Kozaburo Tamamura (1856-1923?) was a Japanese painter. In 1874, he opened a photo studio in Asakusa, Tokyo, and in 1883, he moved to Yokohama and opened a studio there. From 1897 to the following year, he created hand-colored art pieces based on photographs of Japan's scenic spots and customs. The number of these art pieces, created at the request of Boston-based publisher J.B. Millett, was estimated to be about one million copies. They can be viewed at the Smithsonian Institution. In worlds where ex-Ketel, SCP-8900-EX exists, this may be the result of the Ennui Protocol.

Albumen prints, also known as chicken albumen paper, were introduced by Louis-Désiré Blanquart-Evrard in 1847 and represented the first commercially available method for producing paper-based prints from negatives. In this technique, paper is coated with a mixture of egg white and salt, and then a silver nitrate solution is applied to make it light-sensitive. Works produced using this method are characterized by the unique luster of egg white, resulting in an exceptionally beautiful finish. Optional gold or selenium toning enhances the color tone and increases its resistance to fading. Depending on the toner, toning might be done either before or after fixing the print. Since the image emerges through direct exposure to light without the use of a developer, an albumen print can be considered a printed image rather than a developed photograph.
