Question

What do you mean by chromatic aberration? How can it be removed?

Answer 1

✔Chromatic aberration, also known as “color fringing” or “purple fringing”, is a common optical problem that occurs when a lens is either unable to bring all wavelengths of color to the same focal plane, and/or when wavelengths of color are focused at different positions in the focal plane.

WAYS TO REMOVE ➡

avoid high contrast scenes;
accurate focus to reduce the LoCA blur, making it look smaller;
stepping down your lens by 1 stop or 2, i.e., by using smaller apertures, to remove LoCA;
