Photography. An art form invented in 1830s, becoming publicly recognised ten years later.

Today, photography is the largest growing hobby in the world, with the hardware alone creating a multi-billion dollar industry. Not everyone knows what camera obscura or even shutter speed is, nor have many heard of Henri Cartier-Bresson or even Annie Leibovitz.

In this article, we take a step back and take a look at how this fascinating technique was created and developed.

Before Photography: Camera Obscura

Before photography was created, people had figured out the basic principles of lenses and the camera. They could project the image on the wall or piece of paper, however no printing was possible at the time: recording light turned out to be a lot harder than projecting it. The instrument that people used for processing pictures was called the Camera Obscura (which is Latin for the dark room) and it was around for a few centuries before photography came along.

It is believed that Camera Obscura was invented around 13-14th centuries, however there is a manuscript by an Arabian scholar Hassan ibn Hassan dated 10th century that describes the principles on which camera obscura works and on which analogue photography is based today.

Camera Obscura is essentially a dark, closed space in the shape of a box with a hole on one side of it. The hole has to be small enough in proportion to the box to make the camera obscura work properly. Light coming in through a tiny hole transforms and creates an image on the surface that it meets, like the wall of the box. The image is flipped and upside down, however, which is why modern analogue cameras have made use of mirrors.

In the mid 16th century, Giovanni Battista della Porta, an Italian scholar, wrote an essay on how to use camera obscura to make the drawing process easier. He projected the image of people outside the camera obscura on the canvas inside of it (camera obscura was a rather big room in this case) and then drew over the image or tried to copy it.

The process of using camera obscura looked very strange and frightening for the people at those times. Giovanni Battista had to drop the idea after he was arrested and prosecuted on a charge of sorcery.

Even though only few of the Renaissance artists admitted they used camera obscura as an aid in drawing, it is believed most of them did. The reason for not openly admitting it was the fear of being charged of association with occultism or simply not wanting to admit something many artists called cheating.

Today we can state that camera obscura was a prototype of the modern photo camera. Many people still find it amusing and use it for artistic reasons or simply for fun.

The First Photograph

Installing film and permanently capturing an image was a logical progression.

The first photo picture—as we know it—was taken in 1825 by a French inventor Joseph Nicéphore Niépce. It records a view from the window at Le Gras.

The exposure had to last for eight hours, so the sun in the picture had time to move from east to west appearing to shine on both sides of the building in the picture.

Niepce came up with the idea of using a petroleum derivative called “Bitumen of Judea” to record the camera’s projection. Bitumen hardens with exposure to light, and the unhardened material could then be washed away. The metal plate, which was used by Niepce, was then polished, rendering a negative image that could be coated with ink to produce a print. One of the problems with this method was that the metal plate was heavy, expensive to produce, and took a lot of time to polish.
