The duplicator was a fantastic tool for photographers. This tool took advantage of long exposure times and allowed photographers to expose a half of the negative at a time. This way they could capture a sitter in a pose on one side of the film before turning the duplicator and having them change position on the other side. People pushing themselves in wheelbarrows was a popular theme, along with boxing themselves and playing chess with themselves.
Double exposure was another trick that left ethereal figures lurking on a negative and produced eerie spirit photographs. A negative was pre-prepared with a view of a figure draped in a sheet, then mounted behind a clean plate for the sitting. The result was a clear shot of a living person with a misty figure floating nearby. While some charlatans sold these as authentic images of the dearly departed, others made a tidy profit by selling humorous spirit photographs such as men acting frightened, with the figure of a woman wearing a sheet gesturing towards them.
Today we live in a world of Photoshop and social media filters that can manipulate images into alternative realities, but AI-generated images are becoming more real with each new iteration. It is becoming harder to differentiate the real from the trick images and relies on the honesty of the creator to declare authenticity. We cannot always believe what we see!
