Introduction to Photography

Photography is the process of recording visual images by capturing light rays on a light-sensitive recording medium (e.g. film or digital CCD). It can be thought of as two pursuits:

  1. Technical: The science of setting up the camera and the recording medium to take images in a controlled way.
  2. Creative: The art of composing good images to capture.

There are dozens of different types of photography. Some areas require specialist knowledge (e.g. scientific photography), but almost all photography involves the same basic principles of obtaining a clear, focused image through a lens and onto the recording medium.

There are also many types of camera. Professional photographers like to have a selection of cameras for different purposes. The most popular type of general-purpose camera for taking high-quality images is the single lens reflex (SLR). If you are interested in photography you will probably want to own an SLR camera.
