libptp2 is a library used to communicate with PTP devices like still imaging cameras or MP3 players (KODAK mc3). You can download files or tweak camera properties using ptpcam program boundled with libptp2. Supported Cameras: Most (if not all) USB still cameras designed after 2002 are supporting PTP. Below is the list of vendors implementing PTP in their cameras: Kodak, HP, Nikon, Canon, Panasonic, Olympus, Konica, Minolta, Fuji, Ricoh
Tint is a photo editor for colour-select effects. It automatically clusters the colours of a photo into groups, and allows each colour to be switched on or off to create the desired effect.
The Unidentified Flying Raw (UFRaw) is a utility to read and manipulate raw images from digital cameras. It can be used on its own or as a Gimp plug-in. It reads raw images using Dave Coffin's raw conversion utility - DCRaw. UFRaw supports color management workflow based on Little CMS, allowing the user to apply ICC color profiles. For Nikon users UFRaw has the advantage that it can read the camera's tone curves. Even if you don't own a Nikon, you can still apply a Nikon curve to your images.
The JasPer Project is an open-source initiative to provide a free software-based reference implementation of the codec specified in the JPEG-2000 Part-1 standard (i.e., ISO/IEC 15444-1).
pfstools package is a set of command line (and one GUI) programs for reading, writing, manipulating and viewing high-dynamic range (HDR) images and video frames. All programs in the package exchange data using unix pipes and a simple generic HDR image format (pfs). The concept of the pfstools is similar to netpbm package for low-dynamic range images.
PFScalibration package provides an implementation of the Robertson et al. 2003 method for the photometric calibration of cameras and for the recovery of high dynamic range (HDR) images from the set of low dynamic range (LDR) exposures.
pfstmo package contains the implementation of state-of-the-art tone mapping operators. The motivation here is to provide an implementation of tone mapping operators suitable for convenient processing of both static images and animations.
