How Photography has developed over the years.
From the earliest times-
From the 16th Century-
Camera Obscura was improved by utilising a simple lens
1666-
1725-
Johann Schulze Discovered the darkening of silver salts by the action of light.
1758-
Dolland Developed the Achromatic telescope lens, this improved the camera obscura image.
1801-
Thomas Young suggested that the retina at the back of the eye contains three types of colour sensitive receptor, one sensitive to blue light, one to green and one to red. The brain interprets various combinations of these colours to form any other colour in the visible spectrum.
1802-
Wedgwood produced silhouettes of opaque objects by contact printing them on silver nitrate coated paper however the images were unfixed and faded in daylight.
1826-
J. Nicephore Niepce produced the first permanent image (Heliograph) using a camera obscura and white bitumen it required 8 hours to expose.
1835-
Fox Talbot using his small "mousetrap" cameras he photographs the inside of his library window at Lacock Abbey, creating the first negative.
1837-
Daguerre, following experiments on his own he evolved a workable process (Daguerreotype). Silver iodide coated copper plate was exposed and developed by mercury to give a single direct positive. He removed the remaining silver iodide with a warm solution of cooking salt, they took 30 minutes to develop.
1829-
Fox Talbot hurriedly prepared and presented papers at the Royal Institution and the Royal Society. Unlike the Daguerre process the image is recorded as a "negative" and had to be printed via a similar process to produce the final "positive". Many positive prints can be made from a single negative
1861-
James Clerk Maxwell demonstrated the formation of colours by combining three light sources of red, green and blue. All other colours, including white, are a mixture of these primary colours. The colours combine by an addictive process.
1947-
Dr. Edwin Land invented an "instant" picture process, first called Polaroid Land. The special camera sandwiched the exposed negative with a receiving positive paper and spread the processing chemicals between the two, after processing these were peeled apart.
1963-
R Edwin LandHis Polaroid Corporation's research team invented the first instant colour picture material.
1984-
Canon Demonstrated the first digital still camera
1985-
2000-
Canon introduced the EOS D30, the first digital SLR for the consumer market with a CMOS sensor.
2002-
Contax introduced the Ndigital the first SLR digital camera with a CCD the same size as a 35 mm frame.
