On 17 October 2009 I (Jos) said goodbye to this
project. I left the project open, but it has not been (yet) 'taken'.
For continuations in the one or the other direction you can have a
look at :
- dlraw-preview where Mike is concentrating on extending with artistic filters. He has more a full blown 16-bit image editing suite in mind.
- jdlRaw where I (Jos) am concentrating more on a pure raw tool that goes further than ufraw but doesn't pretend to be a full image editing suite. Also I intend to spend more time on documentation and Windows/Linux availibility.
About
To get the best results out of your digital camera, it is recommended
to record your pictures in RAW format. This format is specific to a
camera and cannot be read directly by image editing applications.
dlRaw is an open-source program to read and 'develop' RAW images from
most digital cameras. It reads raw images using a modified version of
Dave Coffin's raw conversion utility
DCRaw.
dlRaw will convert your RAW files into JPEG or PPM images. JPEG is
a standard format to view, print and share your images. PPM is a
bit representation of your image suited for further processing, for
instance in The Gimp.
dlRaw has a GUI to open a RAW file and experiment interactively with
the controls. That way you can see how different settings influence
the image. The so obtained image can be written or the settings
can be stored in a 'job' file.
This job file is used by a command-line oriented batch mode
to develop a set of RAW files.
