Transcript of camera

The evolution of the camera Pinhole Digital Camera When light passes trough a small hole it can project an inverted image. The concept of digital photos appeared due to the Cold War and to the Space Race. A camera is a device that stores photographs or moving images such as videos.
The term "camera" comes from the Latin term "camera obscura". The first partially photograph dates from 1816. Nicéphore Niépce used a special paper which darkened when exposed to light. This kind of photos wasn’t permanent since they always ended up being exposed to more light, hence ruining the picture. Ten years later, he took the first permanent photograph ever taken.

In the beginning of the 20th century, the flash of the camera was caused by a lamp, so the photographer had to change the lamp any time he took a picture. It was invented in 1939 by Louis Dauerre and Nicéphore Niépce and was the first camera that took permanent pictures. Daguerreotype In 1861, James Clerck Maxwell photographed a tarton ribbon using three filters on the lens (one blue, one green and one red). The three images that he took got togheter creating the first colour picture known as "Tartan Ribbon". Colour Photograph In the beginning of the 20th century, Kodak introduced 35mm films in the market, even so photographic plates were still used since the quality of the pictures was better. 35mm Film The first instant camera was created in 1923 by Samuel Shlafrock.
This kind of cameras gave us a printed picture a few minutes after the photo have been taken. Instant Camera Brownie Camera The camera obscura was used since Ancient China and Ancient Greece and it was based on the same principle as the pinhole.
Since pictures couldn't be saved it was only used to help artists making their paintings. Camera Obscura Cameras are a development of the camera obscura, which already exists since Ancient China and Ancient Greece. But, at that time, the projected pictures couldn’t be saved and now they can be saved easily. The first cameras were room-sized, with space for more than one person inside, but they evolved becoming smaller and more compact. In the beginning of the twentieth century, Kodak's started a line of cameras called Brownie with the purpose of taking photography to the people. 35mm film had a major advantage: it was much more practical since it came in film rolls easy to replace and, when a film roll ended, people just had to send it to the factory and they revealed the photos. Thanks to 35mm film, motion pictures became possible. Single Lens Reflex Camera This kind of camera uses a mirror and prism system that allows the photographer to see exactly what will be captured in the photo. The first digital camera was made in 1975 by Kodak company. It recorded images in black and white, weighed more than 6 pounds and took 23 seconds to take a picture.
The first digital camera that recorded images as a computerized file dates from 1988 and recorded
until 16 MB.

Between 2001 and 2003, digital cameras hit the markets and started to be very enjoyed by
consumers. How could they take pictures million miles high if the roll film couldn't be taken back to Earth? Introduction I really enjoy taking pictures, so I decided to make this work about the evolution of the camera to get to know the ancestors of the modern digital cameras.
I'm going to talk about some of the majors steps in the evolution of this device and I hope you enjoy my presentation as much as I enjoyed making this work. What is a camera? Curiosities I really enjoyed making this work because it was very interesting since I've learned many new things about cameras and their evolution.

Now I know that the first colour picture ever taken it's a combination of three images (one blue, one red and one green), that people had to send their roll films to the factories to have their pictures revealed and that the first true digital camera dates from 1988.
