The same reference data can be used for
photographs taken with different lenses or
at different apertures. Reference images can

software. A grid pattern is displayed when
reference images are viewed on the camera.

Flicker Reduction

Reduce flicker and banding when shooting under fluorescent or
mercury-vapor lighting during live view or movie recording.
Choose Auto to allow the camera to automatically choose the
correct frequency, or manually match the frequency to that of
the local AC power supply.

Flicker Reduction
If Auto fails to produce the desired results and you are unsure as to the
frequency of the local power supply, test both the 50 and 60 Hz
options and choose the one that produces the best results. Flicker
reduction may not produce the desired results if the subject is very
bright, in which case you should try choosing a smaller aperture
(higher f-number).
