Description Michael Skiba 2009-04-11 03:02:24 UTC 
Version:           0.11.0-svn (rev.: 950468M) (using 4.2.69 (KDE 4.2.69 (KDE 4.3 >= 20090406)) "release 1.3", KDE:KDE4:UNSTABLE:Desktop / openSUSE_11.0)

OS:                Linux (i686) release 2.6.25.20-0.1-pae

I've some NEF files here and the preview looks different than when I open the image in the image editor. I don't know if this is intended, but since the "preview" also looks different in 100% view or more it means I could as well use the preview, couldn't I? (looks to me as if the preview has already undergone some sort of whitebalance and brightness settings ...)

Left preview picture, right one in the editor.

this file is invalid.

Raw preview use by default the preprocessed JPEG file embedded in RAW file, for speed-up purpose. It's not RAW image !

If you want the same rendering, go to setup/album-view and set on option "embedded preview use full sized image".

I thought such a thing already. Is it possible to extract this JPEG somehow? (or apply the same filters to the original image?)
