photograms (roughly 44%) correspond to de facto paper sizes. From 75 prints from negatives, only 25 (33%) correspond to the de facto paper sizes. This survey shows that Man Ray most likely trimmed his photographs from negatives, but didn’t trim his photograms. Averaging about 3.5 mm thickness, the photograms fall into the category of double weight papers.
Man Ray’s process contrasted with the working practices of Laszlo Maholy-Nagy. Print dimensions and estimated thickness for 216 prints by Maholy-Nagy made in Germany between 1922 and 1928 were collected from the catalogue raisonne of his photograms. Of these photograms, 216 or about 89% correspond to the de facto standard sizes identified by this research. The majority of the prints made from negatives were printed on two sizes of paper, 18 x 24 cm and 13 x 18 cm, both de facto standard sizes. This shows that Moholy-Nagy used full sheets of paper for his photograms and didn’t trim them down. The catalogue raisonne describes the thickness measurements of many Moholy-Nagy photograms as single weight or double weight. According to these descriptions Moholy-Nagy used the single weight or double weight papers in equal frequencies and sometimes used both in the same series.
Understanding the de facto standard sizes provides a useful point of comparison of these two artists. Differences in their methods can be due to a variety of factors. Moholy-Nagy was known for his scientific approach to photography, as a record of the interaction between light and physical object composed within the border of the paper. His photograms were complete upon processing. In contrast, Man Ray was more acutely engaged in producing highly refined settings of expression; attention to detail and subtle manipulation apply to all aspects of Man Ray’s photography as evidenced by his skilled practices in retouching and using carefully proportioned mounts.
In summary, there really were a lot photographic paper sizes available, particularly in middle of the 20th century, when these papers were extremely popular. While there are some de facto standard sizes and thicknesses, silver gelatin papers were made in numerous sizes and the majority of paper sizes listed in the references occurred only once.
