Noise Reduction; Iso Sensitivity Settings - Nikon D3300 User Manual

Noise Reduction

Select On to reduce noise (bright spots,
randomly-spaced bright pixels, lines, or
fog). Noise reduction takes effect at all
ISO sensitivities, but is most noticeable at higher values. The
time required for processing at shutter speeds slower than
about 1 s roughly doubles; during processing, "l m" will
flash in the viewfinder and photographs can not be taken. Noise
reduction will not be performed if the camera is turned off
before processing is complete.
If Off is selected, noise reduction will only be performed as
required; the amount of noise reduction is less than that
performed when On is selected.
