Thanks for the tip. What I ended up doing was : - export individual panorama stacks at their respective exposure - export them after matching the exposure of each stack to the other stack's exposure. This means I ended up with as many panoramas as the number of stacks squared (^2). I did this by right-clicking in the photo list, then selecting "Manipulate image variables" and entering a formula like Eev=val-2 (or +2) - in Gimp, import everything and group by exposure level (so each "exposure" group contains all the stacks with matching exposure) - mask in the parts I want so that all the tree branches are fixed accross all groups - export each exposure group - import them in a new Hugin project - Export the fused panorama
I noticed some limitations with that technique that might have a solution (not found yet) : - At first I tried manipulating the exposure variable on an imported single panoramic image (previously exported from Hugin) instead of manipulating the original pto with the individual photos but this did not give the same colors. This meant I had to manipulate the exposure on the original pto for exporting the "matched exposure" panoramas. This wouldn't be a problem if blending was deterministic but since it's not, the same stack at different matched exposures was not consistent in the blended parts, since branches move between individual photos. - As you'd expect, matching the exposure doesn't produce an identical result as the exposure you matched. For example the blue sky may be blown out in a high exposure photo, so if you bring it down to match a lower exposure where the sky is blue, you'll end up with a grey sky. This was totally expected. However, I did not expect some other color differences, like the over-saturation of green leaves or the slight difference in contrast in some areas. Not sure if this can be solved, though it wasn't too noticeable in the end result. -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
