Instantly create High Dynamic Range images, without the need to take multiple exposures. All operations are performed in a 16-bit dynamic range for maximum editing flexibility.
+more much more feat....

that looks pretty cool.... indeed I always thought why take multiple exposures when my raw 16 bits has all I need..
Thanks for the link..

But I think even a raw image has a limited range of fstops it can capture, you won't get back detail from blown highlights for example. You still need to take multiple exposures.

as mihai says, there's no way you can get the wide range of a good hdr with a single exposure, 16 bit or not.

Yes, this is just using standard color correction tricks to improve the look of LDR images, it's not making them "hdr," nor is it "pulling" information out of an hdr image, it's simulating an "hdr-ish" tonal range by using filters - filters whose auto-selection regions, by the way, are very artifact-y and hard-edged like JPEG noise.

yes but taking raw NEF photos with the Nikon d200, and opening them in Capture NX, I can re-expose a photo pretty well.. but I reckon, it is better to take slightly over exposed photos... than under-exposed ones...
all good then..
Is there any tool that does NICE tone mapping photos... all I've seen for now is "so so"...

It depends what's most important to you in the photo. If you think you might want more shadow details, take it a bit overexposed, and underexposed if you want more room for adjusting the highlights. If your camera has a histogram function, it's the best place to look at which areas will most probably be lost, and adjustment later is very limited.
