But this time I'd rather not share the photos (and they were not raw, they were from my cell phone, which has a much worse camera then most cell phones). I hope on my vacation (which will be later this month) to be using my new camera and mostly with a 105mm lens shooting mostly scenes that ought to be much wider, and so will need hugin when I get home (and those will be raw). I expect some of those will be better examples with which to ask for help.

I will gradually be learning that. But this panorama has large continuous areas of high contrast detail that need to be split by seams. I think I understand the concept of a program identifying higher contrast areas and forcing the seams to not be there. But I can't see how that could work in this example and I haven't yet gotten it to work in examples where I think it ought to. This one needed avoiding exposure correction, so I chose "Exposure fused from any arrangement" (possibly due to not really understanding the choices). But I don't have stacks and the panorama would be wrecked by any exposure correction that I've seen in action. Many upper parts of the image need to end up darker than many lower parts even though in the real view the darkest thing in the upper third was brighter than the brightest of the lower third. As I understand it, exposure correction starts with undoing the "error" from combining images with very different exposure and then might mitigate the consequences by a nonlinear mapping of a brightness range with extra bits back onto a normal brightness range. But in many of my photos, no such mapping can fix the dynamic range problem. Anyway, that choice on the Stitcher tab selects both enfuse and enblend, then I'm unclear on what each does in this example. Before the masks were improved, fusing or blending (I don't understand which) was happening in areas with great detail and with about a 1.5 pixel misalignment between the images in that area. I couldn't get better results than that from optimize (even before I starting forcing Hfov to be wrong). That was enough misalignment to turn sharp sections of both originals into a blurred section of the 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.
