Yesterday I got my new amazing Canon 450D camera. But very soon I was really disappointed when I found the fact that my lovely ufraw can not handle new Canon CR2 (raw) images correctly.
As far as I know, ufraw using dcraw program for raw images conversion. More, last dcraw version 8.86 works good with my files. So the problem lays in the old version of dcraw used by ufraw. In right, the most up to date ufraw distribution contains dcraw.cc version 8.80. So the problem would be solved by patching dcraw.cc.
After some digging I found few lines in newest dcraw.c file related to Canon 450D.
And here we go with patch, which help us to solve the problem!
