1. How do I indicate to hugin which one is the median exposure?
Hugin detects correctly which the median exposure is by looking at the
images. So for this purpose it doesn't matter which sequence the
images are inside the stacks. But if you use align_image_stack, it
assumes that the median exposure is in the middle (I tried with 3-shot
brackets), and if it isn't it wil not deliver it's optimal result:
I tired with the stacks straight as my Canon camera produces them, so
image 0, 1, 2 having exposures +0, -2 and +2 EV. align_image_stack
produced CPs between image 0 and 1, and 1 and 2. This isn't optimal,
because now it has matched the median shot with the darkest, and the
darkest with the brightest. When I put the median shot one down (so,
swapped image 0 and 1), align_image_stack did the same, but now this
was the right thing: darkest and median, and median and brightest.
Hmmm, on my Minolta, I can set the bracketing to shoot the median
exposure in the middle: -2, 0, +2. Maybe your Canon can do the same?
