Did you know that in some ways older cameras were very similar to guns? But in what exactly? Keep reading to find out.
Back in the old days some dry plate cameras were modelled on Colt revolver mechanisms, whilst cinema cameras used the design of machine guns. The first paper negative made by William Walker and George Eastman of Kodak used guncotton. Later on, gelatinised guncotton was created, which was used to make smokeless gun powder. And then amyl acetate, nitroglycerine, and acetone were added to this.
This way, the catridges of cameras and guns used similar chemicals all the time.
