Noise and sensitivity

Sensitivity can be changed in a wide range: from 200 to 1600 "plus two 1/3 steps". But if you look at the shots made with different sensitivity settings you will see that brightness, with ISO increased by 1/3, changes regularly: "dark-normal-light-dark-..." frame. If you look through EXIF data for a series of shots with ISO increasing by 1/3 for each shot you will see that the exposure step (exposure / aperture) actually can be 0, and only the exposure error can be changed by approx. 0.6 EV. We can say that this small and "precise" ISO step of 1/3 means shooting with a small error, and the actual step is 1. For shots with equal exposure errors (step 1) twice higher ISO corresponds to twice lower exposure. 

Below is a series of fragments 1:1 with the gamma increased in the Photoshop. The shots of the D100 in Windows applications require a higher gamma, which can be explained both by orientation toward an alternative system and by a "desire" to delivery details in highs. Since the exposure error didn't correspond to the series in case of sensitivity of HI1 and HI2 (all had -0.3EV), the gamma correction for the HI was fulfilled to make the image equivalent in brightness. Besides, we made two shots for each of these "record" ISO values - in the auto exposure mode and in the manual one, twice and 4 times lower than the exposure of a frame with ISO 1600. All non-HI ISO values have an acceptable noise level, while 3200 and 6400 should be used only when they are really needed. The noise reduction works with exposures longer than 1/2 s.
