The pictures are extremely dark which makes it hard to identify and align details for stitching, particularly over homogeneous trees.
It also looks like th elevation may increase in the tree area (which are already 30 m higher than the ground) 30 m or so. That looks to be where it did not map well. Flying higher with 75/75 overlaps would help.
This helps explain what happens in areas like that.
Have tried doing remaps with image exposure adjusted. But they come out worse, with more areas unstitched.
That said, any good tips on auto exposure adjustment software? When I try LIghtroom auto it blows out to the max.
If you want to message me your email address I can send you a Sharefile link to upload your photos to and I will try my post-processing and run the map on our account? I can send the edited images back to you as well so you can retry on your account…
