What is a camera?

What is a camera?

Cameras come in many shapes and sizes, the first "camera" was invented 100s of years ago and named The Camera Obscura. This camera did not record an image like film or digital cameras, it worked like a pinhole camera by projecting an image onto a viewing plate where an artist would trace over. 

The next generation of cameras were fixed image cameras where the image is recorded. the first successful image was made by Nicephore Niepce in around 1816, the image was recorded onto paper coated in silver chloride, this paper darkened when exposed but this made the image only temporary which would be no use in most applications. bitumen was then used with this camera and the exposed areas would harden then unexposed areas dissolve away, leaving an image behind

Within the time between this and film, dry plates were most commonly used in multiple designs which were like prototypes such as field cameras, disguised cameras and twin lens cameras which were used for a while.

The TLR stood for "Twin Lens Reflex" one lens was used for focusing and viewing your image through a viewfinder and the other for capturing the image onto a dry plate.

The invention of film brought cameras to life and really kick-started the image-recording revolution. George Eastman pioneered the paper film, his first camera which he called the well known "Kodak" was first sold in 1888. the camera was a single lens with fixed focus and one shutter speed! the Kodak came pre-loaded with 100 film and once used it had to be sent back to the factory for resetting and enveloping. this camera was the first "automatic camera" as the slogan for sale of the Kodak was "you press the button and we do the rest."


So, now that film has been introduced into the world, out comes the new line of film single lens reflexes (SLRs). Manufacturers from all around the world such as Olympus, Pentax, Canon and Nikon started mass producing these film slrs with new lenses due to the high demand from this new craze. 














So, the film era is making a killing as millions of people own a new SLR camera. But what's this? A new camera which can focus its self! Nikon realised that manual focus was both slow and inaccurate, therefore they created the Nikon F3AF, this was still a film camera but performed like our digital SLRs today and is similar in terms of design.


This then started a new manufacturing innovation when companies such as canon and Nikon started manufacturing Digital cameras where it auto-focuses and has a screen where you can see your images without processing! This was a big event in camera history and this event soon developed with hundreds of different types of cameras now, from PRO DSLRs all the way down to phone cameras. 


Now we have millions of cameras around the world and over 80% of all images uploaded to Facebook were taken on a smartphone! What will the future of digital imagery hold?
