PhaseOne are offering the beta version of the next release of Capture One as a free download. Capture One Pro has always been just about the best RAW processing tool so hopefully v.4 will continue to improve things.
thanks Robert, I forgot to mention that PhaseOne normally do a purchase upgrade offer i.e. buy the current version for a reduced rate and get a free upgrade to the new version. I'm assuming the same will be true of V.4.
The new Version 4 of PhaseOne’s RAW capture software is out of BETA and available now as a full product or upgrade. This is just the update to the LE version by the looks of it, version 4 of the Pro Suite is due early next year.
