Stray light (veiling glare) degrades image quality by fogging important details in darker areas, but it can be challenging to measure.

Imatest founder and CTO Norman Koren presents a technique that uses two images of the Contrast Resolution chart, taken without and with a mask, to obtain:

• A measurement of veiling glare
• insight into its effect on camera performance, especially the visibility of objects in darker areas
• two DR measurements
