I have previously posted 2 dusk shots, one of them a true HDR pic precessed with Photoshop CS3 alone. I have now processed the same true HDR pic with Photomatix. I think the result is much better. The colors are more natural and there is a lot more detail, especially on the surface of the sea.
The first pic is the version processed with Photoshop CS3 only and the second pic was first processed in Photomatix and then in Photoshop CS3.
