ImageMagick

Warning: The 64Bit version of ImageMagick does not seem to work with PDF on Windows.

If you have dark images it is due to one of three problems:

1. Upgrade to ImageMagick 6.7.5-2 or newer 6.7.7-7. Compile with UFRaw and Tiff Library

./configure --prefix=/usr

make & make install

2. Use 8 bit for normal color levels.

3. Change the raw handling to corrent brightness

#Shows list of config files

convert --debug -list delegate

/usr/etc/ImageMagick/delegates.xml

 <delegate decode="dng:decode" command="&quot;/usr/local/bin/ufraw-batch&quot; --silent --create-id=also --out-type=png --out-depth=8 --exposure=auto &quot;--output=%u.png&quot; &quot;%i&quot;"/>

On 64bit Windows make sure you copy gswin64.exe to gswin32.exe
