[Digikam-users] 100% magnification for JPG and DNG (RAW)

[Rei Shinozuka]

I am running digiKam 1.0.0-beta5 currently on Ubuntu 9.04, but the 
behavior I am about to explain has been with me well before digiKam  
version 1.0.

When I set my camera to take JPG and DNG (RAW) simultaneously, the 
camera deposits both JPG and DNG files of the same image capture on the 
SD card.

In Digikam, I find that JPG will zoom to 100% (keystroke "1") as 
expected, but DNG will zoom far less.  In fact, I must zoom DNGs to 207% 
to achieve the same magnification as 100% in JPG.  When I click on an 
image in an album, the JPG would come up and say "Zoom: 21%," and the 
identical image as DNG will say "Zoom: 43%." (also just over 200% of the 
JPG)    Somehow the scaling in DNG is confused.

Digikam sees the files:

Type: RAW Image file (DNG)
Dimension 3,920x2,638 (10.34Mpx)
Bit depth: 16 bpp
Color mode: Uncalibrated (RAW)

Type: JPEG
Dimensions: 3,936x2,624 (10.33Mpx)
Bit depth: 8 bpp
Color mode: YCbCr

The camera is a Leica M8.

Other RAW formats I have seem to exhibit the same behavior, RWL (Leica 
DLUX4) and CR2 (Canon RAW).  NEF (Nikon RAW) files I have don't seem to 
show this problem.

Thanks in advance,  I am a huge digiKam fan, I rely on it 100% for photo 
editing and organizing.
