A couple nights ago, I noticed that the skies just before sunset were
very pretty, so I took some HDR panoramas. I don't know when I'll
get around to processing them as either HDR or pano, but I've got the
raw files. I just realized that using the same data that they use
for astrotracer, and storing things like position, and xyz of camera
direction, they could write software that would quickly, and very
accurately stitch together panoramas, knowing where the camera was
looking in each frame.
Along the same lines, they could also use the exposure data in each
frame to construct HDR mapping.
Even storing accurate accelerometer readings you could correct for a
tilted horizon in post processing, even beyond what the image
stabilization is capable of.
I have a related question. Is there some sort of rule of thumb as to
how much you should bracket when doing an HDR? Or is it simply as
little as you need so that you aren't blowing away any highlights or
shadows?
