[Digikam-users] raw file conversion

[Thomas Worthington]

I suspect that what's happening is that the thumbnail view is extracting  
the thumbnail that the camera made, rather than the actual RAW image, in  
order to greatly speed up the process. When you edit you should get the  
actual RAW image which will have none of the automatic adjustments that  
the thumbnail has (since the thumbnail is in fact not RAW in any way).

I'm having a similar problem with my Fuji but in my case it's because the  
"use secondary sensors" checkbox seems to be missing so I'm only getting  
half my RAW data downloaded.
