When did all kinds of cameras appear?

1844, sculptor and photographer f? Matos has successfully developed a panoramic shake-head camera. This camera relies on the rotation of the lens and the shooting angle can reach 150. Matos used it in a 5× 17.5 inch silver plate, and successfully photographed "Parisian scenery" and other scenic photos. Later, this kind of camera was often used to take group photos.

185 1 year, d? D Brewster (178 1 ~ 1868) invented a camera that can shoot stereo photo. When using this camera, you can see stereo photo through the stereo as long as you change the subject slightly from left to right and shoot twice. However, this shooting method is limited to shooting still objects.

Two years later, J was in Manchester? b？ Dancer (j? B. Dancers, 18 12 ~ 1887) and Paris A? A.Ouinet has successfully developed a dual-lens stereo camera based on a single-lens stereo camera. This kind of camera, with a lens spacing of 65 mm, can take two side-by-side photos at a time, which is equivalent to the scenery seen by two eyes. Use "binocular glasses" when looking at photos, so that the left eye can only see the photos on the left and the right eye can only see the photos on the right. In this way, the photos seen by two eyes are fused into a three-dimensional image. In this stereoscopic image, the objects in the foreground are very prominent, while the objects in the background are far away.

1854, French portrait photographer a? AdolpheDisderi invented the multi-lens camera. It is equipped with four lenses, and one negative can take eight photos. If the focal length of the lens is different, it can also take photos of different scenes such as the whole body, bust and close-up of the head at the same time. Its appearance brought the popularity of "business card portrait".

Large-size photos look more beautiful, but it is extremely difficult to enlarge photos in early photography. Therefore, photographers must rely on large cameras to obtain large-size photos. In early cameras, the fuselage was generally larger. The camera made by Kibble of 1860 is the best in the world. This is a monster with wheels that must be drawn by horses. It uses 44×36 inch glass plates, each weighing 44 pounds.

Forty years later, this record was broken by a giant camera nicknamed "Ma Meng" (the name of an ancient colossus). This camera weighs 635 kilograms and is operated by 15 people at the same time. You can take pictures with a length of 2.4m and a width of1.4m.. Each of its glass negatives weighs 225 kilograms and needs 45 kilograms of medicine to be cleaned. At that time, in order to take clear photos of the latest luxury trains, alton Railway Company in Chicago, USA, specially ordered this camera, and specially designed railway truck transportation for it. This camera has only been used once, and the only photo taken was exhibited at the Paris Expo in 1900, and won the "first prize in the world".

While taking big photos, people have not forgotten to develop a small camera that is easy to carry. 1858, t in Britain? Scarf (t? Skaife) invented a "pistol camera". This camera looks like a pistol, with a particularly clear lens, and can take snapshots with a diameter of 1.5 inches. When shooting, as long as you pull the trigger, the rubber switch will trigger the automatic spring and the lens will open immediately. Once, when Skaf used this camera to photograph Queen Victoria, it caused a misunderstanding and was almost arrested on the charge of "murdering the Queen". When commenting on this camera, Herschel once wrote: Taking pictures with this camera is like taking an emergency shot.

Perhaps Herschel got some inspiration from it. This year, he first put forward the word "snapshot".
