dcp2icc is a small utility to convert DNG camera profiles to ICC profiles. To get DNG camera profiles for different cameras, download and install a recent version of DNG Converter from Adobe.

dcraw is an ANSI C program that decodes any raw image from any digital camera on any computer running any operating system. It's become a standard tool within and without the Open Source world. It's small (about 3000 lines), portable (standard C libraries only), free (both "gratis" and "libre"), and when used skillfully, produces better-quality output than the tools provided by the camera vendor.

This program writes short movies with your Canon DSLR camera directly to the computer. The camera must have Live View feature to work; supported models include Canon EOS 450D, Canon EOS 1000D, Canon 40D, Canon 50D, Canon 5D Mark II, Canon 1Ds Mark III. The program offers preview, Av, Tv, and WB control. While some newer models provide video recording natively, this program can be useful if your camera does not have this option. Video will be recorded using MJPEG codec, with no sound, roughly at 22 FPS (depends on your hardware: camera and computer). Image size is also camera dependent: 848x560 for 450D; 1024x680 for 40D, 50D, and top models; 768x512 for 1000D. Resulting file is simply a collection of Live View frames stored sequentially without any compression in AVI container (expect file size to be quite large).

gphotofs is a FUSE filesystem module to mount your camera as a filesystem. This allow using your camera with any tool able to read from a mounted filesystem.

GDChart is an easy to use, high performance library/C API for creating charts and graphs in GIF, PNG, JPEG and WBMP format.

The Generic Image Decoder (GID) is an Ada package for decoding a broad variety on image formats from any data stream to any kind of medium. Examples include in-memory bitmap, a GUI objecct, another stream, floating point data for scientific calculations, a browser element or a device. Animations are also supported. GID features: * Standalone; requires no other libraries or bindings * Completely portable - no OS, CPU, or compiler dependencies * Task safe * Endian-neutral * Free and open source * Pure Ada95 (suitable for Ada2005 and Ada2012 projects) Currently supports BMP, GIF, JPEG, PNG and TGA formats.

Provides a wrapper to the GraphicsMagick library.

Jhead is a command line driven program for manipulating the non-image parts of Exif flavour JPEG files that most digital cameras produce. It has the following features: - Extracting camera settings from Exif image files - Able to set and/or adjust the Exif time field - Manipulation (extract, replace, regenerate) of Exif integral thumbnails - Transplant Exif image header from one JPEG to another - Edit JPEG comment fields - Automatically rotate images upright (using jpegtran) according to "orientation" tag. - Manage running programs on large batches of Jpegs and restoring Exif header information afterwards. - Display embedded GPS info (if present)

jpeginfo is used to generate informative listings of jpeg files, and also to check jpeg files for errors. Program also supports automatic deletion of broken jpegs.

A command-line program to create PNG images from LaTeX math expressions.
