What is a photograph?
"To take photographs is to hold one's breath when all faculties converge in the face of fleeing reality. It is at that moment that mastering an image becomes a great physical and intellectual joy." - Henri Cartier-Bresson
A photograph (often just called a photo) is an image (or a representation of that on e.g. paper) created by collecting and focusing reflected electromagnetic radiation. The most common photographs are those created of reflected visible wavelengths, producing permanent records of what the human eye can see.
Most photographs are made with a camera, which focuses the light onto either photographic film or a CCD or CMOS image sensor. Photographs can also be made by placing objects on photosensitive paper and exposing it to light (the result is often called a photogram) or by placing objects on the platen of a flatbed scanner.
