<p>This is a piece of info I previously posted in this mail list:<br>
"... Elle, just out of curiosity. What do you have against DNG? The way I see DNG's is as a secure way to store your negatives. I use Canon, so if one day Canon decides to stop supporting cr2 format I already have my negatives in an open-source digital negative format."</p>
<p>DNG is an open source format. CR2 is not. I keep converting all my CR2 files to DNG. An extra step that gives me some added piece of mind. </p>

Hi Andrew,<br>
<br>
Many thanks for the info.<br>
<br>
I'm using DK 2.4.1 on KDE 4.7.4, if that helps.<br>
<br>
I had been converting to DNG, but lately questioning whether I want<br>
that extra step. So good to hear your opinion about it.<br>
<br>
In DK I under Settings/configure digikam/Metadata I'm looking at<br>
"Write Metadata to RAW files" which is checked and under that is Read<br>
Metadata from XMP sidecar files" which is greyed out- unable to check.<br>
Maybe it is dependent on another item being checked/unchecked.<br>
Otherwise I'm not seeing where that would be.<br>
<br>
cheers, Jim<br>
