Parent article: Working with raw images on Linux

I think libopenraw[1] is worth mentioning.
"libopenraw is an ongoing project to provide a free software implementation for camera RAW files decoding. One of the main reason is that [WWW]dcraw is not suited for easy integration into applications, and there is a need for an easy to use API to build free software digital image processing application.

It also has the goal to address missing feature from [WWW]dcraw like meta-data decoding and easy thumbnail extraction."

Author's blog[2] seems also interesting.

missing feature from dcraw like meta-data decoding and easy thumbnail extraction

Actually dcraw has thumbnail extraction ("-e" option) and support for the most common Exif fields. Another free (as in beer) program based on dcraw that runs under Linux (and Windows) is Raw Therapee.

dcraw is updated frequently (16 times since the beginning of the year). Keeping up with the changes is a major challenge for projects that do not just call the executable.

There is also RawStudio which appears to handle multiple images.

I keep finding myself using the crappy Canon software for windows since it allows me to adjust sharpness, saturation, etc, and work in batches easily. (Pull up 100 images, tweak WB and exposure on a few, and then start a convert.) The user interface of this software leaves much to be desired, though.

I'd love to have a Linux replacement. I'll try these other two soon, but UFRaw just doesn't cut it.
