Chromatic Aberration (CA) is problem caused when lenses refract different wavelengths (colours) of light and the senor records this as a coloured fringe. This is usually most visible on backlit subjects. Higher quality lenses will cause less Chromatic Aberration in the same situation as a lower quality lens. This effect […]
