D3 ISO Test for Don
 

Hi Don and others - camera on tripod - 17-35 mm f2.8 Nikkor lens set at 35mm Aperture Priority semi-auto setting; manual ISO from 100 to 25600. Presented in order. f9.5 throughout - Examples continue on next thread.

All I have done is load them into Aperture and resize to 800x530 - and yes I know I should have decreased the aperture on the last two!

Here we go

Thanks for your efforts Andy. Very difficult to tell any difference at that level of size reduction.

Now for a request. Is it possible to post 1000 wide selections from the ISO range of a crop from the frame. Suggested crop is less than 100% but does have a wide range of tones.
