Non-TTL Auto
A sensor measures illumination without viewing through the

Red-eye
A phenomena caused by the reflection of light off the inside of
the eye, resulting in red spots appearing in a subject's eye in
color photographs. This effect is not caused by equipment, but
rather by the relative position of the flash in relation to the
subject and the camera’s lens. Red-eye is not always
predictable.
