Another test (with more to come) to validate ISO performance in a natural and not all that easy environment (again with shifting light, etc).
After downloading, but before viewing, here is what I would recommend:
Click the Master Reset Arrow in Capture One (left turning arrow in top toolbar that points to a vertical line - which, in Copenhagen, means, "Back to the starting line!") This then resets all adjustments. There were some contrast adjustments made for the finished EIP files and my preference is for you to begin viewing in an "as shot" state, without adjustments.
Then pull the Luminance Slider in the Noise Reduction Tool all the way to the left (value of 0) and the Details Slider to the right to a value of 70. That way you can see all the noise structure and grain without smoothing.
Also - I’ve asked for the color checker shot, if I come up with it, I will have it added to the shot selection.
Overall - once you’ve reset the adjustments, they look pretty impressive for 100 megapixel high ISO.
The Schneider 110mm/2.8 lens was used on the XF Camera for all of these shots. I also noticed the apertures used ranged from f/2.8 to f/22. I would not recommend using any lens on the IQ3 100 at a smaller aperture than f/11, if optimal sharpness is the objective. So the last capture with an aperture no smaller than f/11 is ISO 800. As a result, the ISO 1600/3200/6400/12,800 captures appear softer than they should be - this is a reflection of the non-optimal aperture used, not loss of detail due to the high ISO (though the 6400 and 12,800 ISO settings used in those captures may also contribute to that).
And, as always, you may download to your heart's content, no email address submission required.
