I needed a break from reading all the squabble of what is best, or better, in another HDR-tread her, so I would like to point out that we have a perfect "in-house"-development going on her, with Martin's Auto-HDR which I have tested several times now.
The original (underexposed) photo:
Run through Auto-HDR v1.17 at 'normal' and 'average' settings.
I had with intend chosen a photo with strong lateral lines / wire-stays because I know from experinece that even Photomatix has problems rendering a smooth sky when it is broken up by strong contrasty dividers, like this here.
This pseudo-HDR came out first-rate, in my opinion! Thank you, Martin for providing us with such a handy tool as Auto-HDR really is. And best of all, the *.exe-file is only 64 KB big !!
Amazing programming, if you ask me!
