The birth of photography              


It’s very easy for many people now to take a photograph with a digital camera or mobile
phone, but it was very different in the early days of photography.

The first ‘camera’ was the ‘camera obscura’, which is Latin for ‘dark room’. A camera obscura is a
dark room or box with a very small hole at one end. When light shines onto an object and passes
through the small hole, the image is projected onto the opposite wall, but is not permanent like a
photo. Artists used a camera obscura to draw objects accurately and
quickly.

The French inventor Joseph Niépce made the first photograph with a camera obscura. He did this by
projecting the image onto a special metal plate. It took about eight hours of exposure
to create the photograph so it wasn’t suitable for taking people’s portraits. But in 1839 Louis
Daguerre developed a better method with a much shorter exposure time. He called this the
daguerreotype and it became very popular for portraits.

With a daguerreotype, it wasn’t possible to make multiple copies from one exposure as the positive
image was fixed onto a single plate. With the invention of a negative, it was possible to produce
multiple copies from one negative. In the mid 19th century ‘visiting cards’ with a photo on became
very popular because they were cheap to produce and people displayed an
album of family photos in the living room.

One English expression people sometimes use when taking photos comes from the early days of
photography. In English when someone takes a photograph, they sometimes say
‘watch the birdie’. This comes from a bird that was used by a photographer’s assistant to get
a child to look in a particular direction.

One interesting early use of photography was to show that when a horse runs very fast all four
hooves are off the ground at one time. To do this, the photographer placed 12 cameras along a race
track to take multiple photos of a horse galloping and the images showed that he was right. It was
only possible to prove this because of photography.

In 1900 the world’s largest camera at that time was built. It was about 2.5 metres by x 1.5 metres
and weighed over 400 kilos. It took 15 men to move and operate the camera. So next time you use
your mobile or camera to take a photo, think about how difficult this was in the early days of
photography.
