Hi, I have a question about an ND filter artifact issue.
When I fly without an ND filter, the recorded video looks completely clean. However, once I attach an ND filter, I start seeing a bright spot artifact in the footage depending on the angle to the sun.
I think it may be ghosting, or an internal reflection between the lens and the filter, but I don't mind a len flare and actually it's cool.
Has anyone experienced this with FPV/drone cameras?
Is there any effective way to reduce or eliminate it?
I know, if a ND filter has a tiny scratch, an artifact spot will appear, but not that case.
