Re: How to merge 2 HDR images? "Christian Drewing" <christian.drewing@googlemail.com> wrote in

So all 6 images are of the same scene, but due to mis-registration
(caused by handheld exposures, and/or object movement) Photoshop can't
manage to complete the merge.
What I'd try in a situation like that, is to do some prior alignment.
Photoshop's alignment attempt seems rather finicky, so it might work
better if you manually reduce the differences in hor/ver alignment. If
you use simple single pixel shifts on a temporary 6 layer version of
your shots in difference blending mode, e.g. with the offset filter,
or the move tool and the arrow keys, all that's left for Photoshop is
rotation and/or sub-pixel alignment.
Maybe that is still too difficult for Photoshop (its alignment or
registration capability is in its infancy), in which case you could
leave the alignment bit to better tools. You could either use tools
for panoramic stitching, or a dedicated tool for HDR creation such as
Photomatix (http://www.hdrsoft.com/). The trial version allows to
align and create an HDR. It also has a tonemapping tool (with
watermarking) that has come a long way since its earlier attempts.
Maybe Photoshop CS3 will do a better job than the current
implementation, we'll have to see.
