The Enfuse plug-in does not provide a decent preview of the resulting image because the current version of Lightroom does not make it possible to build plug-ins like is possible with Photoshop unfortunately. Question: are you planning a version of photomatix that works more like the enfuse lightroom interface? I got this e-mail from the guys over at photomatix:

I was wondering if it handled this kind of DR any better than PhotoMatix. It's also the reason I was asking your opinion about Enfuse. (please disregard the distortion and poor composition in these, they are crops from a 360º VR) Something you have obviously mastered already! I'm still struggling with the technique - trying to find an appropriate balance between efficiency and quality. Overexposed trim elements are the lesser of two evils for me but they are still evil! The trouble I am running into now is finding a way to ease the transition (quickly) between the two drastically different scenes.

That's why I still usually take the extra step of combining the best HDR blend once again with the best exterior exposure to come up with something that is less technically correct yet more pleasing to my eye. When you absolutely have to have that balanced exterior view you need to push PhotoMatix very hard toward the dark end of the blend - which invariably produces dark window trim elements and an overall underexposed look to the interior altogether. I find this is where the limits of PhotoMatix really start to show.
