Nikon Coolpix P330 read noise vs ISO
The Nikon Coolpix P330 was measured at 8 ISO settings from ISO 80 to ISO 6400. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (80) read noise is 1.32 DN. From ISO 400 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
