installation file for Windows and Mac OS X. For Linux, it comes in the form of
source code to be compiled.
Another GIMP hack that simulates the interface, characteristics, and menu
layout of Adobe Photoshop is GimPhoto plus GimPad . For information and
downloads, go to This version is based on GIMP
2.4.3. However, it has some built-in plug-ins such as a CMYK color separation
and various photo effects, and it offers a multi-document interface (MDI).
Another image editing program derived from GIMP is Cinepaint
(previously FilmGIMP ). It was developed to edit movie sequences from digital
movie productions. Cinepaint supports 8-bit, 16-bit, and 32-bit color channels
of deep paint. In contrast to GIMP, Cinepaint can read and write CMYK images.
Most interesting for photographers is the fact that the program is able
to compute high dynamic range (HDR) images from normal bracketing
You will find further information on Wikipedia's web page http:// as well as Cinepaint's home page, http://www. . You will find links for the free download of the program for
Linux and Mac OS X. A windows version is being developed at the moment
but isn't available yet.
At this point, I would like to point out an open-source competitor to
GIMP: Krita (Swedish for crayon). It is the bitmap graphics editor software
included with the KOffice suite based on the K Desktop Environment (KDE)
and is available for Linux. Krita supports the color models RGB (8-bit, 16-bit,
and 32-bit), LAB (16-bit), grayscale (8-bit and 16-bit), and CMYK (8-bit and 16-
bit). The program supports the OpenEXR format (EXR for short) and can be
used by photographers for editing HDR images. You can find information on
Krita on its own website,, and on KOffice,
krita. As part of KOffice, it is available for all three major operating systems.
1.5.2 Installing GIMP and Plug-Ins
GIMP works on the three major operating systems—Windows, Mac OSX, and
Linux—as well as on some less popular systems, such as BSD and Sun Solaris.
This section concerns itself with installing GIMP on your system.
The topic's DVD includes all iles
required to install GIMP on Linux,
Windows, and Mac OS X.
Installing GIMP under Windows
GIMP doesn't run by itself on Windows. You'll need to install a runtime
environment, a separate file provided by GTK+. In earlier versions of GIMP you
had to install GTK+ as a separate file. Now GTK+ is included in GIMP 2.6. It is
sometimes necessary and often advantageous to also install GhostScript ( GS )
and the GhostScriptViewer ( GSView ) for Windows in advance. If you want
to employ a Python script, you must install PyGTK+ and the corresponding
