Thanks for that. Perhaps I should also open a new thread as what I'm trying to ascertain is not S/N ratio as base 200.

Hi Cafe Racer,

I am not sure whether I understand your question.

Hi Architeuthis,

You've put in a lot of work here so I'll try to explain what I was trying to find out.

I put my Panasonic G80 on a tripod, I select Raw, switch to manual exposure mode and take two photos. Both photos are of exactly the same scene (nothing in the scene changes).

Ist photo taken at ISO 400 - 1/500 sec - f4

2nd photo taken at ISO 200 - 1/250 sec - f4

Would you expect those two photos to look the same?

This is not a trick question by the way.
