Ohanaware has released HDRtist Pro 1.0.1 (http://www.ohanaware.com/hdrtistpro/) for Mac OS X 10.5 (or higher) running on an Intel Mac. The upgrade sports over 50 changes, which includes the ability to specify bit depth and compression on export.

HDRtist Pro now performs better when used on Macs without hardware acceleration. Also, Ohanaware has fixed a bunch of small bugs.

HDRtist Pro is the more advanced version of Ohanaware’s freeware HDRtist. It’s been designed to provide more creativity with HDR images, while maintaing an easy-to-use interface, according to the folks at Ohanaware. Utilizing Apple technology, HDRtist Pro is able to wield and manipulate 128-bit floating-point images (that’s 16,843,009 times more precision than a JPEG photo).

The app’s engine has been designed to work with multiple exposures, single RAW images, and can make single JPEG images look like HDR. One-click styles, editable HDRs, and a “drop-N-click” system are all featured in HDRtist Pro.
