Camera Obscura & Pinhole photography The earliest known written account of a camera obscura was provided by a Chinese philosopher called Mo-tzu in 400BC. He noted that light from an illuminated object that passed through a pinhole into a dark room created an inverted image of the original object. this is the start of photography history santa maria della salute venice abelardo morell (using the pin hole method) Nicephore Niepce & Heliography: Niépce developed heliography, a technique he used to create the world’s oldest surviving product of a photographic process: a print made from a photoengraved printing plate in 1825. In 1826 or 1827, he used a primitive camera to produce the oldest surviving photograph of a real-world scene.Louis Daguerre called his invention daguerreotype. His method which he disclosed to the public late in the summer of 1839, consisted of treating silver-plated copper sheets with iodine to make them sensitive to light, then exposing them in a camera and “developing” the images with warm mercury vapor.calotype is a early photographic technique invented by William Henry Fox Talbot in the 1830s. In this technique, a sheet of paper coated with silver chloride was exposed to light in a camera obscura; those areas hit by light became dark in tone, giving a negative image.Cornelius had set his camera up at the back of the family store in Philadelphia. He took the image by removing the lens cap and then running into frame where he sat for a minute before covering up the lens again. On the back he wrote “The first light Picture ever taken. 1839.Julia Margeret started photography when she was 48 in 1863, She used the most common process at the time, producing albumen prints from wet collodion glass negatives. The process required a glass plate (approximately 12 x 10 inch) to be coated with photosensitive chemicals in a darkroom and exposed in the camera when still damp. what makes Julia’s work different is she includes imperfections in her photos that other photographers would reject as a technical flaw, she was criticised at the time for this however today people can appreciate these imperfections. Wikipedia say she took 900 photo in 12 years.Henry Mullins started working at 230 Regent Street in London in the 1840s and moved to Jersey in July 1848, setting up a studio known as the Royal Saloon in his career in jersey he took 20,000 photos he specialised in carte-de-visit photos he charged one half of how much a photo was in London
