Brief History of Photography

Old Photography and later turns to Digital Photography
Although photography is over 200 years old, digital imaging actually predates photography. The Romans and Greeks grouped small tiles to make up a picture. We call these mosaics, the reality is that they are pictures made up of hundreds or thousands of small coloured tiles just like today’s digital images.

The Photography as we known from now started with a camera and the basic idea has been around since about the 5th Century B.C. For centuries these were just ideas until an Iraqi scientist developed something called the camera obscura sometime in the 11th Century. Even then, the camera did not actually record images, they simply projected them onto another surface. The images were also upside down. The first camera obscuras used a pinhole in a tent to project an image from outside the tent into the darkened area. It took until the 17th Century for camera obscuras to be made small enough to be portable and basic lenses to be added.
