Adobe Photoshop is the leading digital image editing software which was developed by Adobe Systems. It was first released in 1989 to display grayscale images on a monochrome display. Today, the program is used worldwide by professional and amateur photographers, print designers, visual communicators, and even ordinary people like you who wish to enhance their pictures, posters, magazines, and any other digital image media.

Adobe is currently on it's 13th major release and it comes in two major version, Adobe Photoshop and Adobe Photoshop Extended. The difference between the regular version and extended version is the 3D image rendering tool, motion graphics editing, and advanced image analysis features. Adobe Photoshop is available for both Mac and PC.

  • Filter brushes
  • Refine edge for selection

Additional features that can be added to the "toolkit" in Photoshop. A lot of people use plug-ins to add extra tools, such as image editing filters, that did not come with the Photoshop software.

Examples of popular plug-ins include:
