Thanks again for your help, Groogle & Erik. I'm now learning a few things that may differentiate my outcome from yours, and that may've resulted in some confusion: - I'm running the Simple interface. (I've played with the Advanced interface, but issues with PTBatcherGUI took me back to Si

With cell phone optics sometimes the upper left corner has a slightly different zoom factor than the lower right. Might it be something like this? Erik Keever schrieb am Di., 30. Apr. 2019, 06:42: > Hi Jim, > > What do you mean not using control points? The usual process is > (1) Load pictures >

Hi Jim, What do you mean not using control points? The usual process is (1) Load pictures (2) Detect control points (2b) Prune bad control points (3) Have Hugin align images (4) Stitch The stitching process is "just" a bunch of computational geometry that projects input images onto the 4π steradi

Thanks for these suggestions; I think I now get how to optimize exposure by overlaying two panos set for different exposures. If you have ideas re. my bigger problem of creating a true 360° pano from the original fourteen images, I'd appreciate! See earlier posts in thread for clarification. J

The horizon looks very good, the trees are straight and the hills naturally curved. I see that the sky colors don't look natural. This has been caused by the automatic exposure and white balance correction. When you use "Align" button, the exposures and WB are adjusted, but they rather adjust
