Features
-
Adobe Photoshop allows the user to edit and retouch existing photos or create new images. It is extremely popular and widely used in the graphics industry.
Function
-
Usually the PSD file is converted to another format such as a JPEG after it is complete. This allows the file to be used by most software packages that can import images.
Potential
-
PSD file formats can be opened by some Adobe programs and other competing image editing programs. The file can then be edited in the new program and saved in another format.
History
-
According to Adobe Photoshop News.com, in 1987, Thomas Knoll wrote a computer code on his Mac Plus computer. This code, originally called Display, allowed the displaying of grayscale images on a black-white bitmap monitor. This initial code was the beginning of a collaboration with his brother John and resulted in the creation of the software package called Photoshop.
