  Now, pretty much everyone has a camera in their back pocket – in the form of a smartphone. It's easy to take hundreds of photos without needing to really consider set up or storage. And it's very hard to imagine that, at one time, capturing an image was an almost impossible process.
  Going back even before traditional film cameras, there were camera obscuras. These were boxes with a small hole in them. Through one side, an image could be projected onto a wall on the opposite side of the box. However, the picture was upside down, very faint, and couldn't be captured in physical form – a bit like the images we see on modern projectors1. In 1839, a French artist managed to work out a way to store and save photographs. He projected the image onto a shiny metal plate treated with chemicals. These images were in black and white. The first colour photo ever taken was of a tartan ribbon. The image was composed of three black and white photographs, each taken through a red, blue or green filter.
  So, how did we get from these early photographs to the kind we put into a frame and keep? Before the digital revolution, an image was captured on a negative, and this method is still chosen by some photographers today. A negative is an inverted2 image on a small strip of glass or plastic film which can then be exposed to light and processed onto photographic paper. When this was the main source of obtaining physical copies of photographs, it was a lengthy3 process with customers having to take the negatives to a shop and wait for their pictures to be developed.
  That was until digital photography came along in the 70s. Digital cameras captured images that could be saved as files and manipulated4 on a computer. Those are the kind of photos we take today on our phones.
  So, don't take the camera in your pocket for granted. It's been years in the making.
