I'm having a look at the images now... Another issue that I've just spotted is that there is quite a bit of movement between some frames, and some of the frames are a bit blurry (presumably motion blur? But I've noticed in some of the frames theres actually blur only one the right side of the frames and not in the centre... peculiar).. I assume you didn't use a sturdy tripod and the camera was blown around a bit by the wind? Also, because you used 4 frames to bracket, presumably you didn't auto bracket (or did you mention your camera doesn't auto bracket? I can't remember now), so you would have had to physically manipulate the camera to change exposures between frames, also resulting in camera movement... Hmmmm. Anyway, those movements between frames has buggered up one idea I was thinking of, which would have required pixel perfect alignment on each frame, but I'll still have a go with Photomatix as it can auto align... Will let you know if/when I come up with something!    | (Talk)   (Contribs)
