The Invention Of The SLR Camera

The first photograph was taken by Joseph Nicephore on a summer day in 1827 with a camera obscura and invention that let dye layers together to create an apparent colour image. With this invention also came flexible roll film which is still used topeople bend light to create images.(was only used before for tracing and other drawing methods). These photographs or sun prints as they were know literately le somt the light draw the picture. This was very time consuming as it took hours for the image to be created and aftere time it faded. It is not until the early 1940s, commercially viable colour films were invented. These films used the modern technology of dye-coupled colours in which a chemical process connects the threeday in some cases. In current photography most camera's are digital and don't require any film as the images are placed directly on to a memory card and instantly ready for viewing,0 Something that Joseph Nicephore could never of imagined.

How It Works

The Single lens Reflex Camera or SLR has a rather simple functionality. It uses a single lens that is in front of a mirror that reflects the light or image into a pentaprism and out to a eye piece. because of the simplicity of the inner workings the image that is shown in the eye piece is exactly what the lens can see. When taking a picture you press the shutter which is usually a button on the top rapidly moves the mirror out of the way and lets the cameras digital recorder capture the image on the film that is located right behind the mirrof the camera and this very or.
