High-Frequency Flicker Reduction - Nikon Z 8 Reference Manual

High-Frequency Flicker Reduction

Selecting [On (shutter speed fine-tuning)] allows shutter speeds between ¹⁄₈₀₀₀ and ¹⁄₃₀ s to be
adjusted in smaller increments in modes S and M, letting speeds that keep flicker to a minimum be
found by viewing the preview in the shooting display.
Flicker may cause banding in pictures taken under high-frequency LED lighting or in shots that
include monitors with high-frequency LED displays. Reducing the size of the increments used for
shutter-speed selection helps in identifying speeds that keep flicker to a minimum.
After choosing a shutter speed suited to your subject, enable high-frequency flicker reduction and
fine-tune shutter speed while viewing your subject in the shooting display until you find a value that
minimizes flicker and banding. The effect can be more readily ascertained by zooming in on your
subject using display zoom.
When high-frequency flicker reduction is enabled, the shutter
speed display shows only the denominator, with a digit added
after the decimal point.
The precise shutter speed is shown. For example, the shutter speed when ¹⁄₅₀₀ s is selected is
precisely ¹⁄₅₁₂ s, which the display shows as "512.0", the denominator.
Turning high-frequency flicker reduction off returns shutter speed to the nearest of the values
normally displayed.
