Canon EOS Noise Reduction (NR) for Different Drive/Shutter Modes
8

Noise Reduction (NR), even with all menu settings OFF, is visualized using 2-Dimensional Fourier Transforms (2D FTs).
When no NR is present the pattern is random; the less random the more NR.

Mosaics are arranged in whole ISO setting order from ISO 50 to ISO 102400
NR is "expected" at 102400 but the NR ar low ISO is "unexpected".

Probably best viewed at "original size".

Mechanical Shutter

High Speed Continuous

Electronic
