A good read on sensors and more

Image
I'd like to give credit to shortcourses.com for the following article. It's a good read on sensor types. For those of you who have never used film, be patient, as the article quickly gets to the digital point. When using a film camera you can insert any kind of film you want. It's the film you choose that gives photographs distinctive colors, tones, and grain. If you think one film gives images that are too blue or red, you can change to another film. With digital cameras, the "film" is permanently part of the camera so buying a digital camera is in part like selecting a film to use. Like film, different image sensors render colors differently, have different amounts of "grain", different sensitivities to light, and so on. The only ways to evaluate these aspects are to examine some sample photographs from the camera or read reviews written by people you trust. Initially, charge-coupled devices (CCDs) were the only image sensors used in digital cameras. T
