With image sensors getting cheaper and more powerful, most serious amateur and semi-pro shooters are opting for the versatile Digital SLR, merrily leaving their film cameras behind. This guide is geared toward people that are already familiar with an SLR photography, but are unfamiliar with the digital process. Shooting with a DSLR is just like shooting with a film camera. All of the common mechanical functions are there, right where you would expect them to be. And, while there aren’t any chemicals to deal with, each image still has to be processed before it can be shared with the universe.

THE SENSOR

In film photography, a chemically treated segment of plastic is exposed to light for a predetermined period of time, permanently embedding an image onto the film. The film is then processed to create negatives, which in turn are processed into photographs or slides. The concept is the same for digital photography, except instead of a segment of film being exposed to light, a CCD (charged coupling device) is exposed and the light is converted into electrical signals that are recognized by the camera’s processor, the files are then stored on a solid state memory device such as a CF card. Each pixel on the sensor captures red, blue, and green information. . . . → Read More: DSLR Basics – Understanding the Digital Camera
