Veiling glare (lens flare)Veiling glare is stray light in lenses and optical systems caused by reflections between lens elements and the inside barrel of the lens. It predicts the severity of lens flare— image fogging (loss of shadow detail and color) as well as "ghost" images— that can occur in the presence of bright light sources in or near the field of view. Veiling glare is measured by Stepchart using a standard Kodak Q-13 or Q-14 step chart beside a "black hole," i.e., a box lined with black behind a small opening, mounted on a large white board, as described in detail in Veiling glare. |
