Yesterday hdrsoft.com announced the release of Photomatix version 4.2. The upgrade to version 4.2 is free of charge for customers who purchased a license of Photomatix Pro version 3 or higher. This is a version that's been in beta for a while. I did a post about the new Realistic Option in batch mode in early April.
The more significant updates in 4.2 are:
I retried my test of the Fusion/Realistic rendering to see if it has been change since the beta version but it looks the same (See the above comparison). Fusion/Realistic does in fact make bright windows darker but it also can't discriminate between the window and the woodwork so the effectiveness of this rendering option will depend on what kind of wood work your windows have.
For beginning real estate photographers that use bracketed images it's worth noting that Photomatix is used by almost 50% of real estate photographers that shoot brackets. Hdrsoft has been doing a great job of continuing to update and improve Photomatix. Great work guys!
