Noise/Noise Reduction Test:
Okay – here are my first real almost-scientific tests, since I haven't had much time to go “out” to take some real pictures. This by no means is a start
of a career in measurebating. LOL. But This illustrates the noise in the different ISO's. And the noise reduction you can squeeze out of the high ISO modes.
First set: Different noise reduction strengths at ISO 1600:
Second set: ISO comparision across ISO 100-800.
One interesting thing from this test, is that I figure the “Noise reduction at High ISO's” must kick in at ISO 800, because ISO 400 seems noisier to me than ISO 800. (though 100 and 200 are just awesome). So in my little test, it seems if I end up using a higher ISO past 200, I'll just jump 400 altogether and go to 800.
All of these pictures are 100% crops from a set, the full picture of which was the beer bottle shown just below:
Expanded Dynamic Range test:
Actually I didn't expect to get to really check this out today, but this certainly seems like it's going to be useful. First exposure is 1/800 sec at ISO 100, second
exposure is 1/2000 sec at ISO 200 with expanded d-range on. Now I know the ISO 200 exposure is not exactly half of what the ISO 100 was, but that
really shouldn't account for the difference I see here, especially in the highlight areas, specifically the detail in the hat, on the coat, etc.
