hmmmm nice pictures.. but not really usable as HDR are they?
I'd call them RAP - Really Artistic Photos
the halo around the buildings... shouldn't appear... just my humble opinion, but perhaps u didn't tweak it enuff... and the 1st pic is so saturated that highlights are blown colour wise..
since u hand held it, the buildings may be displaced each photo u take, so you shouldn't force it. shld match the buildings manually so that they overlap perfectly, then crop what's needed, then do your blending...
heh but the photos looks nice in their own right... i like the hotel one.. v nice
