On a large 7500 photos ortho photo project, I notice that there was some color issues on some parts of the ortho. I figured out later that this was due to a significant difference of exposures at some points where pictures were taken the day after the previous ones. Is there a way to replace the relevant pictures by the same ones with retouched exposure to correct the issue without going through the whole process (AT, reconstruction, production) again?
Try to do retouch. Still it will require at least to regenerate the changed parts.
Retouch is definitely a way to do it. But I was wondering if you can retouch the pictures directly between an AT and a reconstruction and improve the result.
Maybe. You could retouch photos then clean the project so it deletes cached photos and then try to regenerate needed tiles.
