Darktable is a virtual lighttable and darkroom for photographers: an open source photography workflow application and raw image developer. It manages digital negatives in a database and lets one view them through a zoomable lighttable. It also enables one to develop raw images and enhance them. Darktable tries to fill the gap between many excellent existing free raw converters and image management tools (such as UFRaw or F-Spot). The user interface is built around efficient caching of image metadata and mipmaps, all stored in a database. The user will always be able to interact, even if the full resolution image is not yet loaded. All editing is fully non-destructive and only operates on cached image buffers for display. The full image is only converted during export. The frontend is written in Gtk+/Cairo, the database uses SQLite3, raw image loading is done using libraw and rawspeed, high-dynamic range and standard image formats such as JPEG are also supported. The core operates completely on floating point values, so darktable can not only be used for photography but also for scientifically acquired images or output of renderers (high dynamic range).

OpenColorIO (OCIO) is a complete color management solution geared towards motion picture production with an emphasis on visual effects and computer animation.

Data Explorer brings together dynamic computational and rendering tools in a dynamic, programmable framework that enables users to rapidly create visualizations of highly complex data from disparate sources. Data Explorer can be used to add visualization capabilities to existing applications. It is used by companies and institutions for applications in a large variety of visualization fields including computational fluid dynamics, medical imagery, computational chemistry, and engineering analysis. For example, it is currently being used to: * Identify and manage portfolio risk worldwide for a large multinational banking group. * Depict oil-flow simulations to improve drilling success-rates and increase reservoir yields. * Piece together over 5,000 ceiling fragments from a 1,200-year-old temple in Peru. * Help insurance agents identify opportunities to cross-sell product offerings. * Visualize developing weather patterns to improve the accuracy of weather forecasts.

Quick Image Viewer (qiv) is a very small and pretty fast GDK/Imlib2 image viewer. It has such nifty features as: zoom, maxpect, scaledown, screensaver, flip, delete, brightness / contrast / gamma correction, and can also be used to set your X11 background. All from a commandline.
