notes Photoshop has achieved such status in the design community and such widespread recognition
by the general public that even non-designers recognize what someone is saying when they
exclaim, “That is photoshopped!” Many of the techniques and methods that are standard
across photo editing software were pioneered in Photoshop, like layers, slices, and image
correcting macros and filters. On its own Photoshop is a titan of photo editing power, but
thanks to a nearly complete dominance in the graphic editing industry, there are entire
companies devoted to creating plugins for it. When it comes to manipulating images, if
you cannot do it in Photoshop, there’s a strong chance you want to be able to do it at all.

Alongside Photoshop and Photoshop Extended, Adobe also publishes Photoshop Elements
and Photoshop Lightroom, collectively called “The Adobe Photoshop Family”. In 2008, Adobe
released Adobe Photoshop Express, a free Web-based image editing tool to edit photos directly
on blogs and social networking sites; in 2011 a version was released for the Android operating
system and the iPhone.

Adobe only supports Windows and Macintosh versions of Photoshop, but using Wine Photoshop
CS4 can run on Linux.
paint.net (Windows, free)
Paint.NET is a proprietary freeware raster graphics editor program for Microsoft Windows,
developed on the .NET Framework. Originally created by Rick Brewster as a Washington State
University student project, Paint.NET has evolved from a simple replacement for the Microsoft
Paint program, which is included with Windows, into a powerful editor with support for layers,
blending, transparency, and plugins.

Paint.NET is primarily programmed in the C# programming language. Its native image format,
.PDN, is a compressed representation of the application’s internal object format, which preserves
layering and other information. Excluding the installer, text, and graphics, Paint.NET was released
under a modified version of the MIT License. It was initially released as completely open source, but
due to breaches of license, all resource files (such as interface text and icons) were released under a
Creative Commons license forbidding modification, and the installer was made closed-source.

Version 3.36 was initially released as partial open source as described above, but the sources
were later removed by Brewster, citing problems with plagiarism. In version 3.5, the license was
altered to reflect this, and users are now prohibited from modifying the software. As free licenses
cannot be revoked, developers can still legally develop forks based on version 3.36 and earlier.
Unlike most proprietary software licenses, however, the new license allows users to decompile
and reverse engineer the software, provided that no modifications are made.
Brewster later stated that he hoped to release portions of the source code back into the public.
