I use convert, from imagemagick. From dpkg -L imagemagick: /usr/bin/composite /usr/bin/mogrify /usr/bin/display /usr/bin/compare /usr/bin/convert /usr/bin/import /usr/bin/montage /usr/bin/animate /usr/bin/conjure /usr/bin/stream /usr/bin/identify Give it a try and see if the quality is good enough for you. I see it does understand .nef files (according to http://www.imagemagick.org/script/formats.php). I just use it to resize and rotate pictures. I'm curious as to how it will compare with dcraw for your purposes. bjb On Tue, Nov 03, 2009 at 07:01:43PM -0500, Peter Sjoberg wrote: > I'm trying to find the best way to convert my raw pictures to jpeg in > batch. > The most obvious answer (for readers of this list) is to use dcraw but I > find the colours to be washed out unless I manually adjust each picture > - not an option for batch mode. > As a test I did use 5 different ways to convert various pictures and put > them up on > http://www.techwiz.ca/~peters/raw/index.html > > > 1. the raw .nef picture > 2. m1 dcraw-plain > 3. m2-dcraw-embedded (-e) > 4. m3-ifrview - > 5. m4-ViewNX - the manufacture provided sw > 6. m5-ufraw - a dcraw rwapper with color profile > Nkx_D60_5_2697_00_002_468.icm that ViewNX created when > converting a picture > > The sad news for me is that what looks best is ViewNX - Nikons own > windows only tool (might work under wine but that's not the point) > When using ViewNX it does create a .icm file for many of the pictures.
