Tech Thursday: Vera Prasilova Scott Photography Equipment- Enlarger


Prasilova was born in 1899 in Bohemia, then part of the Austro-Hungarian Empire. A talented artist, she apprenticed under famed Czech photographer Frantisek Drtikol (1883-1961) at the age of 18, and went on to earn a Master’s from the Graphic Arts School in Munich, Germany. Eventually, Prasilova opened and operated a successful photography studio in Houston, where her clientele included Rice faculty and well-to-do members of the community. Her work has been exhibited at the Museum of Art, Portland, Oregon, the Museum of Fine Art, Houston, and the Museum of Czech Literature. See the finding aid for her collection for more information on Prasilova, and the Rice Digital Scholarship Archive for examples of her work.

An enlarger is used to magnify the image captured on a photographic negative or transparency. The principle of an enlarger is simple: a light projects the negative image through the lens at the bottom of the enlarger and onto photographic paper. The size of the image can be adjusted by moving the lens nearer to or farther from the paper, or by moving the negative nearer to or farther from the lens. The patent number identifies this enlarger as an E. 0. ROGERS PHOTOGRAPHIC ENLARGER, and it conforms to the design on the patent.

The track controls the distance between the lens and the negative. The enlarger itself can slide up and down on the back board.
