Just ordered my M1 and was wondering if anybody has a set of images I can practise my software technique on. Would like an 'easy' set that contains a Nadir obviously and a set that may present problems. I use Autopano Giga.
The pts file is a PTGui Pro project file. The stitch was produced entirely with that project - no Photoshop tweaking applied. You may be able to import the project file as a PanoTools project, though there are some viewpoint images that Autopano Giga probably cannot handle which would need to be deleted.
It is the file of the "project". It saves everything you have done in PTGui. Masking lens settings etc etc. With the pics and the project file you can open the whole project and see the result. You can check the control points, Max Distance of CP etc.
Ah I see thanks. Been watching various tutorials and can't understand why 2 Nadir shots are taken.....1 from straight down and the other slightly offset.....as both show either the tripod head or legs. Why not just take the -90 and then mask/edit the head out?

When you "mask/edit the head out", you have to replace the areas occupied by the head/tripod etc. with something. For the perfectionist, the answer is for that something to be what is actually obscured by the said head/tripod. That can only be captured by moving the tripod out of the way. You can then photograph the unobscured nadir area either from the side (to avoid shadows) or with the camera close to where it was when it was originally on the tripod (e.g. using a nadir adapter such as is available for Nodal Ninja heads). The nadir editing can then be carried out either during the stitching (using PTGui's viewpoint correction, for example) or manually in Photoshop - usually working with rectilinear views extracted from the equirectangular panorama image for convenience. The end result is then a perfect rendering of the entire 360x180 view, including the nadir area - however inconsequential that may happen to be. Cloning away the head/tripod using data from the surrounding area is often done when the floor/ground is characterless - such as gravel, grass, concrete - or when there is a repeating pattern of tiles or floorboards. Alas, this cloning is often carried out inexpertly leaving all-too-visible copies of obvious features. But the word is that this is completely unimportant as nobody looks at the nadir area anyway. Take your pick.
