This is a guest post from fellow photographer Sergio Valverde.
I want to share with you a tip for handheld exposures. I have a Canon EOS 450D and this camera can shoot at 3 fps, that it is not very fast and it is easy to have a little movement between exposures. What I do to resolve the problems with alignment is to use ‘Merge to HDR Pro’ in Photoshop CS5 to select one of the exposures with the Ghosting removal tool included (besides PS generates less noise). I usually select the 0 EV or -2 EV, which is the best exposure when you may have had camera shake and to be sure that the exposure time is less than 1 / (equivalent focal length). After selecting 32 bits mode, I save the result as an .exr or .hdr file. Finally, I load this file in Photomatix and do tonemapping.
Thanks for reading and happy shooting
