Hi there... for a while my orthomosaic has been showing these white spots...Does anyone else have this problem?
The problem showed using 2 different Phantom 4 RTK, one bought 2 years ago and the other one bought 1 month ago.

We found a similar problem with our orthomosaics producing white stripes along the flight paths. Took us a while to figure out but finally learnt that this was due to the individual photos showing a "vignetting" effect.

To fix this we re-captured the imagery with the shutter priority turned on and set at 1/1000 shutter speed. We also increased the side-lap to 80% instead of the default 70%.

Hope this helps
