The Inventions of Photography
In the 17th and 18th many artists used camera obscura which helped them to develop skills that became new art. The 19th century was when the camera obscura was was ready where only a little or no modification to take a 'photograph' which was a sheet of light material that was sensitive that became the photographic camera.
It was in 1800 when the first 'photograph' was made. This was done by Thomas Wedgwood and Humphry Davy were they had sensitised paper or leather with silver nitrate and then placed a flat object in contact with the paper and then exposed the paper and object to light which created the photograph, also known as 'sun prints'. Unfortunately they were not permanent.
It was then in 1826 when the first permanent photograph was taken. This was by Joseph Nicephore Niepce. The exposure time was 8-10 hours with bitumen coated plate in a camera obscura. It was a negative (reversed) image and it is called 'Heliography'.
In 1839, the first person in an image was created by Louis-Jacques-Mande Daguerre. The plate contained a latent image and the exposure at the end needed to be developed and fixed.
From Daguerre, photography expanded as in 7th Jan 1839 he announced his invention and then 19th Aug 1939 he joined a meeting of the Academy of Science and the Academy of Fine Arts in Paris and demonstrated his invention.
