Reduce flicker and banding in the display and in movies while
shooting under fluorescent or mercury-vapor lighting. Choose a
frequency which matches that of the local AC power supply.
When a photograph is taken or a movie is recorded, the camera
names the file by adding one to the number of the previous file
(0 145). If the current folder is numbered 999 and contains
either 999 photographs or a photograph numbered 9999, the
shutter-release button will be disabled and no further photo-
graphs can be taken. To reset file numbering to 0001, select Ye s
for Reset file numbering and then either format the current
memory card or insert a new memory card.

If you are unsure as to the frequency of the local power supply, test
both 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 select mode A or M and choose a
smaller aperture (higher f-number).
