The camera obscura, darkened chamber/room is an opticaldevice that projects an image of its surroundings on ascreen. It is used in drawing and for entertainment, and wasone of the inventions that led to photography and thecamera. The device consists of a box or room with a hole inone side. Light from outside passes through the hole andstrikes a surface inside where it is reproduced, upside-down,but with colour and perspective preserved. The image can beprojected onto paper, and can then be traced to produce ahighly accurate representation.
Sir John F.W Herschel was born on 7th March 1792 and died on 11May 1871 (aged 79). His parents were called Mary Baldwin andfellow astronomer Sir William Herschel. He was the father of 12children. In his career of astronomy he named seven moons ofSaturn and four moons of Uranus. His most famous contribute tophotography was cyanotype. Cyanotype is a photographic printing process that gives a cyan-blue print. The process was popular in engineering circles well into the 20th century. The simple and low-cost process enabled them to produce large-scale copies of their work, referred to as blueprints. Two chemicals are used in the process: • Ammonium iron(III) citrate • Potassium ferricyanide.
The first moving image was invented from a bet by Eadweard Muybridge, Eadweard believed that a horse lifted all legs up at one point while running. So he placed 12 cameras. All the same distance apart, all the camera took a picture and when he put all the pictures together it developed the first moving image. He did prove his point as you can see from YouTube in the link below.The First Moving Image video here.
The first Kodak cameras were created in 1888, the firstcameras were evolved from the camera obscura, andkept changing through the ages like things such asdaguerreotypes, calotypes, dry plates, film, and digitalcameras etc.
Oskar Barnack was in charge of research and developmentat Leitz ( a camera company), started to investigate using35 mm film for cameras while trying to build a compactcamera capable of making high-quality enlargements. Hebuilt the prototype in 1913 but further development wasthrough world war 1. The camera was put into market at1925.
The instant camera is a type of camerathat generates a developed film image.The most popular types to use self-developing film were formerly made byPolaroid Corporation.The invention of modern instant camerasis generally credited to American scientistEdwin Land, who unveiled the firstcommercial instant camera, the LandCamera, in 1948, a year after unveilinginstant film in New York City. The earliestinstant camera, which consisted of acamera and portable darkroom in a singlecompartment, was invented in 1923 bySamuel Shlafrock.
Digital cameras differ from their analogpredecessors primarily in that they do not usefilm, but capture and save photographs ondigital memory cards or internal storageinstead. Their low operating costs haverelegated chemical cameras to niche markets.Digital cameras now include wirelesscommunication capabilities (for example Wi-Fior Bluetooth) to transfer, print or share photos,and are commonly found on mobile phones.
