Hello- I’ve seen this before on low quality cameras, but does anyone know what causes this blue “halo” around white objects in this frame and how to resolve it (in camera)?
That is called chromatic aberration, it is a physical limitation of a lens. Higher end cameras that employ more expensive lenses and chromatic aberration correction software will have less of it.
You will get CA when:
-You are using a long lens (zooming in a lot)
-High contrast
-low cost gear
