avoiding dots is aerial pano

[éric Thoreau]

Hello, 

When stitching drone pano & enabling expo fusion, I get dots as shown in the screenshot.

How can I avoid them ?

Thanks

Hi éric,

I would need to try myself, could you make your project file and source
images available for download?

Kind regards,

Hi éric,

You can solve it by changing this:

Exposure/HDR tab - HDR Workflow:
Create blend planes first, then merge to HDR.

This way, PTGui performs exposure fusion on the blended panorama, not on
the individual source images. The latter may cause brightness
differences between the images.

I agree that this is not obvious, I'll see if the defaults need to be
changed here.

Kind regards,
