RawTherapee – a free raw picture editor/converter

April 29th, 2010 No comments


a few days ago i found this very nice raw-picture editor and converter. its pretty close to what you can do with the commercial variants like adobe lightroom, apple aperture or bibblepro.
the nice thing with this piece of software is that it also supports linux systems. which from the commercial ones only bibblepro does. thumbs up! dope stuff.
you can find out more here: http://www.rawtherapee.com/?mitem=2
AND DONT FORGET to donate the author a bit.

compile dcraw raw image converter under debian lenny to support canon eos 7d .cr2-files

April 20th, 2010 No comments

after a long search i finally found a method to compile dcraw under debian so that it can handle the raw files of my canon eos 7d.

just do the following:
download the c-source from http://www.cybercom.net/~dcoffin/dcraw/dcraw.c
open a terminal and navigate to the folder you downloaded the c-source.
then install two libraries needed for compiling dcraw

apt-get install libjpeg62-dev

apt-get install liblcms1-dev

after that compile dcraw with the following command

gcc -O3 -o dcraw dcraw.c -lm -ljpeg -llcms

then copy the compiled version of the program (dcraw not dcraw.c) to your /usr/bin

now you are set.
navigate to a folder with raw pics and just type

dcraw *

now it will batch convert all the containing raw files

i found this info here: http://www.camerahacker.com/Forums/DisplayComments.php?file=Digital%20Camera/RAW_converter_for_linux
