Sharp source images and blurred stitched panorama

[Piero B]

Hello, I need urgent support (I've a Pro license).

I've 20 very sharp shots (4 sides with 5 bracketed shots)  . Stitching with PTgui I get a blurred panorama, especially in certain zones, for example:

Maybe I've setted something wrong? Lens settings (sigma 8mm circular fisheye) were setted automatically.

The project + 20 shots here: https://drive.google.com/open?id=1uSsSVr1czp5ZqCGCCxzsBECZqKfRnJyK

many thanks!

You have not observed the rules for shooting HDR panoramas.  You need to use full manual exposure mode in the camera so that the exposures are identical in each bracketed set. You must not use auto exposure mode.

See tutorial at https://www.ptgui.com/hdrtutorial.html .

I selected one set of images for aligning with the optimizer (the first of each bracketed set) and aligned those.  Then I linked the remaining images in each set with the first image of their sets. I then selected 4 images of reasonably matching exposures for generating the inside scene and created that panorama. Then I selected a different set to create a panorama with the outside nicely exposed.  I then merged the two panoramas with EnfuseGui and got a quite reasonable result. I have uploaded the two project files and the final merged result to: https://www.sendspace.com/file/ng83gt .

In tab "source images" select the group of bracketed images and right-click "link selected images" repeat for all images, then run "create panorama".
see attach project. (some masking too)

thanks John, you solved my problem!!

I didn't follow the rule because in each side (4 sides) I tuned the exposure in the best way, and then I shooted a set of 5 bracketed pictures.

Just  a question: if I have a side with so much brightness, and a side with so much shadows, how can I set the exposure?

thanks

Piero, You set the exposure so as to capture both sides adequately in one or other of the bracketed images.
