<DIV><FONT face=Arial size=2>Hallo Everybody!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm a "digital photographer", and I would like
to ask you a question, that still haven't found answers after my researches.
I'm not so expert, but before asking to you, I checked on the documentation
and in Internet, no results.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>When I download raw (.CR2) photos from my
digital SLR, I used to convert them in this way:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>dcraw -T -w *.CR2</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>...and I got "standard" tiff pictures. Then, I
installed Digikam, and I got similar results using the raw batch converter,
leaving the recommended settings (use camera white balance, automatic color
balance), only changing the savefiles to TIFF.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>But what really shocks me is this: as soon as I
download the CR2, Digikam shows the thumbnail...and the
thumbnail of CR2 has better colors than the thumbnail of the converted
TIFF!!!</FONT></DIV>
<DIV><FONT face=Arial size=2>My question is: which parameters are used to
generate the thumbnail from the CR2? I suppose that dcraw is
used.</FONT></DIV></DIV></BLOCKQUOTE>
<DIV><BR>The thumbnail are generated to extract the jpeg image embeded in RAW
file. (dcraw -e option)<BR><BR>RAW files are container : raw image data +
reduced JPEG image + metadata. <BR><BR>The reduced JPEG image is used to
render picture on TV screen very quickly. <BR><BR>Same behaviours when you
display the Preview of RAW picture (F3 in Album GUI). Of course it completly
different when you edit image (F4 in Album GUI). In this case the real RAW
image data are used. <BR><BR>Gilles Caulier</DIV></DIV><BR>
