Camera Bits today has released a public beta version of Photo Mechanic 4.4.3, the next release of the pro photo browsing software for Mac and Windows. Highlighting the list of changes is the ability to upload directly to a PhotoShelter account in Photo Mechanic on both platforms, improved CD/DVD burning in the Windows version and numerous other fixes and enhancements.
The Mac version of 4.4.3 also marks the return of RAW conversion to the program after a several-year absence, this time utilizing the RAW support built into the Mac OS.
