WebDigital camera sensors are highly reflective objects - much more so than film. Some lens systems, under some conditions, can actually pick up the glow of the image falling on a sensor and reflect that glow right back onto the sensor. The size and intensity of the reflection will depend on the size and curvature of the lens elements (especially ...
