Raw Therapee is a free, multi-platform alternative to Adobe Photoshop Lightroom (RAW converter and digital photo processing software).
Shooting in RAW format is great for the photography buff. However, when it is time to share with others, post on your photo gallery, or print at the local photo printing shop, you want something more portable. Here we'll look at converting RAW photos (specifically Canon's CRW format) into JPEGs using a batch command-line approach in BASH.
In this article I’m going to show the benefits of storing the photos in RAW “format”. I’ll be also decribing GNU/Linux tools that can help you with processing such images.
The free software RAW photo converter Rawstudio released version 1.0 in April, marking the culmination of two years of work. This release carries on the Rawstudio tradition of providing a lightweight, dependable tool for photographers.
If you're finding DigiKam or F-Spot, two of the many photo organization and editing tools for Linux, a bit limiting you may want to give Lightzone a try. The software isn't free, and curiously, isn't available for purchase either, but judging by the 20-day demo version currently available, it could end up a serious contender in the hybrid photo editing/managing market.
If you have a point-and-click digital camera made by Canon, you may be able to turn on all sorts of features usually reserved for more expensive SLRs. That includes live histograms, depth-of-field calculation, under and overexposure highlighting, and -- best of all -- shooting your pictures in RAW. The secret is CHDK, an enhanced, free software replacement firmware.
The popular open source RAW converter UFRaw recently gained new functionality when it was bumped up to revision 0.12. The new release integrates new core image-processing functions and new user interface features to simplify photo editing.
