Chromatic aberration is the name given to the ‘fringes’ of colour around the edges of objects in an image. It occurs because each colour in the light spectrum is on a different wavelength, and the extremes of cheaper lenses can’t always focus these different wavelengths at the same point, and so creates a colour fringe around objects.
