There is a checkbox called "Attempt to Automatically Align Source Images" in File/Automate/Merge to HDR Pro...
It seems to me that it does nothing. Even when I shoot with tripod and the unaligment of source images is very small, the end result is also off.
When and how should this automatic aligment work?
I have Photoshop CS5
Here are 3 shots of the moon http://www.fi.tartu.ee/~nils/astronomy/HDR_moon/
These are taken at the same session and in the same conditions. The only difference is the exposure time.
However, Photoshop Automate/Merge to HDR Pro function says that "Merge to HDR Pro - Images to merge may have taken with different cameras"
