There are a lot of differences between film and digital photography. Most devices able to recording video are camera telephones and digital cameras primarily meant for still photos; the term “camcorder” is used to describe a conveyable, self-contained machine, with video seize and recording its major function.

A slower velocity film will exhibit much less “grain”, and a slower pace setting on an digital sensor will exhibit less “noise”, while increased film and sensor speeds permit for a sooner shutter velocity, which reduces motion blur or permits the usage of a smaller aperture to extend the depth of subject.

This course of is still employed by both newbie and skilled photographers, but the introduction of digital imagery signifies that the overwhelming majority of modern photographic work is captured digitally and rendered via printing processes which can be not depending on chemical reactions to light.
