I shoot real estate for xtra cash and used the bracketing feature of the k20d routinely. I tried the hdr 1 setting on the k7, da12-24mm with the metz48 and then did a quick dodge and burn and a perspective adj in post processing in CS4. I'm using this feature quite a bit as it is reducing my post processing time. I find it very useful and convenient. heres a not so great interior sample (kinda messy) but it illustrates the lighting in a contrasty environment. to achieve the same result with the k20d required merging a flash shot and 1 or 2 non flash shots and then further editing. i tried the hdr2 setting but it does not appeal to my clients

Yeah, hdr1 could prove very useful in this situation. Where you bring your tripod, maybe anyway to do some pano shots.

BTW, how well do the hdr1 shots stitch to panoramas? Exposure-wise, I mean.

That would be interesting for a cityscape night shoot. I may try that in Chicago on my next visit. I suspect the hdr2 setting might work well, but its anyones guess on the pano merger

How do you know?

Enfusing three exposures is generally much faster than creating a HDRI and then doing tonemapping. Would require less resources to do and is faster. Would be kind of stupid to offer just few tonemapping settings (HDR modes seen by user) which would work with some scenes and not with others.

Well, consider it "speculation with possible proof" for now! I've spent many, many years in the computer vision and imaging end of the software industry working on HDR processing along with the researchers in this field, and I just finished comparing tonemapping algorithms for my employer's 3D rendering software (again!). The differences of the "lighter" method to a particular fusion method are too minimal to be a fluke. It also makes the most technical sense for limited hardware like a camera, as fusion minimizes the memory overhead and doesn't require increased processing precision (which is expensive in every sense of the word, and would yield benefits well beyond this one feature). It also falls in line with much of the filtering and convolutions almost all modern DSLRs do, and the sad "market truth" that floating point output (exr, etc.) would cause huge confusion among consumers.

To add to the evidence, the advance K-7 brochure copy says "HDR 
capture 
quickly
 snaps
 3 
images [...] 
then blends 
the 
best 
parts 
of 
each 
into 
a 
single 
output 
image." Tonemapping isn't usually described that way.
