How can I change the default settings for new panoramas?
Choose ‘Make Default’ in the file menu to save the current settings as a starting point for new projects. This will save all settings, except for the images and control points. Even though you changed the defaults, the Project Assistant will still override certain settings (such as the panorama projection) in order to ensure a good result. Your file format settings will not be overridden if you switch to Advanced mode before generating control points. If you really need full control over all settings, don’t use the Project Assistant: if you instead choose ‘generate control points’ in the Control Points menu, PTGui will do only that and leave the other settings as they are.
