Digital photography is a new way of photography. New cameras have "arrays of electronic photodetectors to capture images focused by a lens"
These kinds of photos are digitalized and kept in computers files. They are generally created by computer or mechanical techniques. The first cameras appeared in the 1990 and they were revolutionary. I changed the art of photography because it eases the photographer job, it replaced the typic film and the printing process which sometimes was complicated, took a long time and many images were lost in the way.
