rather than create a new thread, i'll hijack Bernidictus'.
Photoshop CS5 will now merge HDR; (click for large size)
Photomatix 3.2; (click for large size)
same three exposures. the photshop merge features 'remove ghosting', which is the difference you see in the flags. there is a way to remove ghosting in a photomatix picture- you import into photoshop.
version 4 of photomatix is in beta, and from what i've seen, 'remove ghosting' is new, along with 'remove noise'. Noise is the second biggest problem with HDR, behind ghosting.
i had just read where there are cameras coming out with HDR on demand, i think they will be point and shoot . . .
