Canon .CR2 pictures to .jpg, all directory

[Harijs Buss]

How do I transform whole directory - hundreds of pictures - in Canon raw .CR2
format to .jpg compressed pictures? I can transform each separate picture
e.g. using Gimp, but it would be too slow and time consuming to do this for
the whole directory (or many of them).

Any advice or link much appreciated.

You could try the ufraw package. It can be used as a gui to apply
corrections etc to .cr2 files but there is also a ufraw-batch utility
that comes with it.

I think there is a version in the repositories (version 0.5 in
universe). I downloaded and compiled version 0.7 from
http://ufraw.sourceforge.net/

the canonical way to batch process images is Imagemagick. Imagemagick
-convert- supports a wide variety of image formats, but RAW formats
tend to be proprietary...

Doesn't gimp have any automation system?

AFAIK for more complex tasks, Gimp has script-fu and python-fu. It has
also a batch mode: http://www.gimp.org/tutorials/Basic_Batch/

Use ufraw, it has a batch mode and you can feed the batch mode
whatever settings you want (white balance, etc). You can even set up
a nautilus script to do it.

For this type of work I use dcraw, my camera is a 350D and the script I
use is a modified version of the one I found in a list somewhere...

#!/bin/bash

(while [ $# -gt 0 ]; do
dcraw -c -w $1 | ppmtojpeg > `basename $1 CR2`jpg
echo $1
shift
done) | zenity --progress --pulsate --text "Converting RAW files to
Jpeg"

I placed the attached file in the 'MyUsr'/.gnome2/nautilus-scripts
folder so when I select the .CR2 files I want to convert it is a simple
right mouse click Scripts... RAW to jpeg

The main change I made to the script was CR2 instead of cr2.

Now what I want is a chromatic aberration filter (as per Adobe CS2) the
17-85mm lens can have appalling CA and and a "scratch" fixer a la Photo
Elements :)
