Yes, this and what Gnome summarized are close to what I was thinking. So, if you have two adjacent stacks of three exposures, presumably they would all overlap by at least 10% and all six images would share a particular control point - thus creating a single line down through both stacks. Presumably, all the "dowel" lines would be radiating out from the camera (and probably mostly parallel by the time they intersect the images?).
I may have been a little confusing by mentioning the exposure levels, but I was thinking this would allow exposure-level priority versus stack-priority? So, if you wanted to make three panos, one of each exposure level, then merge as a single stack (maybe in another HDR program) you can do that. The reason I can't (quite/easily) do that now is that I'm hand-holding the camera rather than using a tripod. When you use a tripod, you know that each image of a stack of exposures has the same framing/rotation/etc, so you can create one pano makefile with all the control points, adjustments, etc, and just switch out the filenames. I can't make those assumptions; creating a pano of each exposure level doesn't get the same rotational/spatial information for each frame, so I can't just swap things around, which causes each exposure level to be projected slightly differently, then the stacks don't line up quite right. Again, the ROI might be a little low, but I have a hunch this might make Hugin a bit more versatile (esp. for semi-advanced users that don't what to lug around a tripod with a pano-head everywhere :D ) On Feb 27, 2013, at 10:19 PM, Tduell wrote: > Hello Bob, > It seems to me that you really only need two "dowels", probably best not too > close to one another.
