are these for fun or commercial?
the HDR is not good, halos colour shifts etc
tell tale fuzziness and loss of IQ from photomatix rendering
what would you use instead of photomatics?
Try the HDR built into the recent Canon DPP update. The good thing is it's free, and you can easily do some subtle looking HDR with presets. DPP certainly has it's critics on this site, but I keep going back to it for some basic edits and RAW conversions.
I will definitely try that. I know lots of people frown on dpp. but i like to use whatever works =-)
I can't recommend HDR for Commercial Real Estate photos. I prefer flash as it looks more natural and pleasing that HDR, Which always has lots of grey tones.
You also want to represent the house as accurately as possible within reason.
I'll do that for certain customers, but so far this company has been always wanting HDR specifically. I appreciate your input!
