Double The Fun
It occurs to me there is a generation of people who have never seen a double exposure, as it’s not something that happens with digital photography. This is one of Ella May Davidson’s negatives. Her camera took an early type of roll film, which had a photosensitive emulsion on a flexible cellulose nitrate backing. A single roll of film in her camera was enough to do expose 12 images, but you needed to remember to advance the film by the proper distance so you didn’t expose the same part of the film twice. Early cameras left it to the photographer to remember to advance the film. Later film cameras has a shutter lockout mechanism so you couldn’t release the shutter again until you advanced the film. It appears Ms. Davidson’s camera did not have this protection, so occasionally we get two exposures on top of each other and have to guess at what the two views were. Since one of these exposures was landscape mode and the other portrait mode it’s a little easier to see the basic subjects, but actually isolating the two images is a hopeless task.
