Raw files contain a JPEG image embedded in the file and this is what you 
are seeing in the preview. This was produced by the camera at the time 
the file was saved and takes into account things such as the white 
balance selected. In the edit window you are seeing how digikam, with 
its current settings, would 'develop' that raw data. As you can see this 
is almost always nothing like how the Canon camera or even Canon 
software would do it. There have been some recent messages on this list 
about the difficulties in getting digikam to produce an image that 
closely resembles the embedded JPEG. This is one of the shortcomings, 
IMO, of digikam in that it starts from scratch for developing raw files. 
Some people find Darktable or Rawtherapee do this job better.
