A few weeks ago I started to work again on camprof to make it usable and compatible with Capture One. (I switched to C1 from DXO since the first version was released.) My initial attempt of a profile maker was hardly usable: relying on scanin from ArgyllCMS made it fragile and slow (scanin is designed for scanning tiffs from scanners not from digital cameras) and the profiles were missing the right curve, so it made photos dull and flat.
I set out as a goal to correct all of this and also make it as easy to use as possible.
I think I achieved these goals so today I release the new version of cramprof:

• New target scanning module with perspective distortion correction
• Improved color accuracy
• TIFF Transfer function tag support for better C1 compatibility
• Generated profiles are fully compatible with C1

You can download it from the camprof page
