okay so this has been bugging me for a couple weeks now. im processing a survey i did over a construction site, pretty flat terrain, flew it in dronedeploy with 75 overlap front and 65 side at about 120m AGL. the raw photos look totally fine but when the orthomosaic renders there are these visible seam lines through certain sections of it, like you can clearly see where images were stitched and in one area theres a noticeable color shift.

its not every flight, ive done maybe 15-20 maps and this is only the third time ive seen it this bad. conditions were slightly overcast which i thought would actually be better for this kind of work. m3e with the stock camera if that matters. anyone dealt with this before

color seams like that are usually a exposure/white balance issue. if your camera was on auto exposure or auto white balance during the flight then each image could have slightly different color grading and the stitching software doesnt always blend that cleanly even with good overlap. try locking exposure and WB manually before your next flight, pick settings that work for the lighting conditions and just leave them. overcast is great for avoiding shadows but if the light was changing at all during the flight that could definitely cause what youre seeing.

yeah what he said about white balance, thats almost always it in my experience. also worth checking if there was any wind causing the drone to roll slightly on passes, that can mess with overlap in a weird way even if the flight logs look normal. 65% side overlap is also on the lower end for construction sites where you sometimes have stuff sticking up at different heights - i usually go 70/75 for anything that isnt completely flat open land
