The beta of Capture One 7.0.2 [download page] has now ended. The terms of the beta will terminate on Monday Jan 14, 2013, at 14.00 CET, where Capture One 7.0.2 will be officially released. Thank you all very much for the participation in making Capture One an even better piece of software. In particular I want to thank all who contributed with comments and raw images.
