You still get an optimizer tab when you set the Optimize -> Geometric setting to "Custom parameters" in the Photo tab.

While reading through it I found 'optimizer tab'. I don't have an 'optimizer tab'. Only 'Photos', 'Masks', 'Control Points', and 'Stitcher' tabs. I can optimize with Edit-> optimize but no tab. -- 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.

This is a special case, Hugin has to assume that most input images are photos taken with Bayer sensors that have higher pixel resolution than necessary. I haven't tested this, but it is also possible that downsizing the pictures removes high frequency artefacts that would confuse the feature detector (leading to better results for digital photos). -- Bruno -- 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.

If you let the edit field untouched then hugin use the unrounded value.

Of course, this is not an error in cpfind. cpfind results can only be as accurate as the input data. Without --fullscale, the accuracy is at least halved. That may be acceptable. But I have total failures seen in the absence of this option, which resulted that hugin run more than 3 hours on a 25x25 mosaic of images with 1000x1000pix (Overlap approx 150pix). The pictures were taken on a scanning electron microscope. After this time I have give up and kill the process. With --fullscale it needs the expected approximately 30 minutes. -- 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.

Michael Havens wrote on 26.09.16 01:18: What does 'optimize' do? I just ran almost the entire process through to the end (2 hours) when I was rereading what I hadn't done when I noticed it was said I did not optimize it. So I stopped, optimized, and started the process again. BUT what does it do? http://wiki.panotools.org/Hugin_Optimizer_tab Further, is there any benefit in running it twice... threee, four times? I think you should start with a simple horizontal, one row set of images taken from a tripod (don't forget about overlap) and play with that through the whole process of creating a 360° panorama without having to care about nadir and zenith. Once you get familiar with the process, include nadir and zenith images in the next step. In the "tutorials" section of http://wiki.panotools.org/ I found a link to -> Panorama Tools - Using The Optimizer http://www.johnhpanos.com/optitute.htm (maybe a bit outdated at several points but I hope you'll get the image) You can always use the Panotools wiki as a glossary. In Firefox you can easily add it to your list of search engines. I also have a feeling that your knowledge of the operating system you're working with is rather basic. Maybe you can also find tutorials about that somewhere.
