Phase One's Capture One RAW conversion software has reached version 4, and arrives sporting a new underlying architecture and interface - so a major upgrade by all accounts. The new interface places the point of focus on the the image - or indeed images as one may now open up to 12 simultaneously at full resolution. Multiple versions of a RAW file may also be created with 'virtually no disk and performance overhead'. The shortcut system has been upgraded too, making accessing frequently-used functions a breeze. Capture One 4 is available now as a free upgrade for existing users or $129 / €99 for first-time purchasers, more after the click.
