Gary,
The situation would be the base ISO is say, 800, but we decide to shoot at 400 or 200 or 100 in an attempt to reduce the noise. We would be doing a proper exposure by using more x2, x4 or x8 the amount of light we would have at 800.
I was just wondering since the sensor doesn’t amplify at base ISO 800, what is it doing under that ISO, and would that really provide a less noisy image, provided we are lighting things properly.
Thanks for your time on this! Much appreciated. : )
Best regards,
Kevin Camin
