Hi Alexey,
Thank you for your reply. I'm a bit confused about your sentense "Brightness adjustment doesn't have any effect on the orthomosaic generation". I got the feeling that if visualization of my data is better (brighter, shows more details and constrast) after brightness adjustment, the stitching works better.
In an extreme case that I've tested : If I don't do any brightness adjustment, the visualization of my data looks completely dark, showing no objects/features at all. If I just do the ordinary workflow on such data, the alignment step fails completely. Is it normal?
Does it mean I should always adjust the brightness to the level which shows as good "quality" as possible? (I mean the results images should be sharp, have better contrast, clearer features, etc.)
