I have been beta testing this for some time and this latest version is worth a look. It is a RAW developer, an HDR processor and a Lighting processor for different images with mixed lighting. Sign up for their Newsletter and qualify for a discount when released. This beta expires June 1st. Link:
Thanks Bill, I see that Oloneo is only available for the Windows platform at the moment - though you can run it on a Mac with Parallels. I used to need Parallels for a previous job I had and found it worked very well.
