Pano halo

[Mwel]

I'm not sure if this is really a bug or feedback.

 

It's been years since I used AP for making a pano, the results were not great then and I used APG instead.

From this recent use AP is doing a much better job, and I will use it first from now on. 

I just wanted to show where one aspect where stitching/exposure values could be looked at for improvement.

In the photo here you can see the pano creation made a halo around the top of the cliff/hills that was not there in the original photo.

 

Thanks

Hi, 

 

sorry to learn about these issues.

it would help to reproduce and identify the root cause if you can add some more context like:

• the source images used
• the afphoto file 
• a short screen recording showing the creation of the panorama 

looking forward to get these updates

Thanks for your offer to help, I've tried to reproduce it and I think I see what is happening. 

I've about 14 photos making up the pano, I shot it twice, so about 28 photos. (My files are Nikon raw from a D90, I don't have great upload speeds so won't try posting them) 

When I make each pano out of each batch of 14 they are okay, but when I use all 28 this halo appears. 

I guess the renderer is trying to do some kind of HDR on the area, anyhow problem adverted just by using one set of images.

Thanks anyhow.

Good to hear you found a solution in your case.

As a general advise for others finding this thread :
In case you have multiple exposures and multiple parts for a pano:

• first, pre-process exposure bracketing images pairs by hdr stack and export as rgb/16 in tiff format
• then stitch panorama of intermediate tiff

Or decide which set of pictures with same/similar exposures is better quality, and only choose one set for panorama stitching
