</span>A jpeg preview is usually stored in the Raw, but at a much smaller size, like<br>
1/4 of the full size. Those jpegs are rendered with the same settings as for a<br>
camera-generated full jpeg apart from the demosaicing, so they should look<br>
identical on screen.<br>

</span>As explained above, the difference between the embedded and the separate camera<br>
jpegs is the size/resolution.<br>
Digikam only renders a jpeg when you ask it to, using the editor. And in<br>
practice it's very difficult to get output from a given raw file that's<br>
identical to the corresponding camera jpeg.<br>

</span>If you mean "should I be saving Raw + fine to get the proper preview in<br>
Digikam", the answer is "no", if you want to have a full format jpeg without<br>
doing the editing yourself, the answer is yes (but if you don't want to edit<br>
the raws yourself, why do you shoot Raw as well?).<br>
