Thanks. In other words, an absolute waste indoors. > This is expected, the 'anchor' image is the photo that doesn't move around > the canvas during optimisation, That is what I wanted and thought it was.

At least I've found out where that point is not, or better, I've discovered one non functioning procedure for how to find that optimum. > Manually fixing control points is not so hard: display the Control Points > table, sort by 'distance', and click on the points with the largest error > distance one at a time, you can easily see which points need to be deleted or > repositioned. Heehee, this is why I wrote "shudder" earlier.

Back to resizing. Or rather cropping. > Tone mapped images are radically changed at a local scale, Ahhh, you're right! That's the whole point of tone mapping. D'oh! > it is possible that they are no longer similar enough for cpfind. That was a new consideration to me. Local contrast also depends on global contrast, and these are not identical from image to image – different subjects.

I already do that, but without knowing that it was useful in this scenario! When shooting the originals, I am always on vacation, and always go back to the forest cabin and stitch the 0EV frames to see that I didn't mess up at the shooting session. But I can ensure everyone that a MacBook Air is not a Hugin powerhouse :( I will have to tell the wife that Bruno Postle himself told me I need a MacBook Pro! :P Thanks again for all the help, always enabling me to take yet some stumbling steps forwards. I should be able to shut up for several days now :P I wonder how all you guys on this list who are not retired – how do you have time for this? :D:D:D Vegard Brenna [email protected] -- 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.
