Rolled Film Camera

been rolled since 1888

How it was invented

The invention of the rolled film starts in 1888 George Eastman invented photographic film that is dry, and flexible. Plus the Kodak camera that could hold the rolled film. He quoted,"You press the button, we do the rest. He wanted all people to be able to take pictures not just photographers. The camera is already loaded with enough for 100 exposures.

How it Works!

It is film rolled on a spool. The photographic film is protected from white light exposure by a paper backing. When you open up the film cartridge you would find a long strip of plastic material with coatings on each side. On the base side you will find a very very thin layer of celluloid. The other side is the most important because it has a layer of gelatin that hold all the components together. There are imaging layers that create the image. One of the most important layer has silver-halide crystals that are light detectors. The crystals go through a photochemical reaction, so that when they are exposed to various types of lights they absorb it and create an image. The backing paper allows you to let the film to be loaded in daylight. The film is usually loaded on one side of the camera. And pulled to the identical to the spool on the other side where the shutter is. Then you pull up the button on the top to get it ready and press and shoot!
