Nikon CoolPix S200 - Test shots - ISO performance

Over the next few pages we show a range of test shots. On this page the full size image at the minimum ISO setting has been reduced to let you see the full image, and below that a series of full resolution crops have taken from original images at a range of ISO settings to show the overall image quality.

----



At the minimum setting of 50 ISO the image quality is good, although there are some compression artefacts visible.

----



Not much difference at 100 ISO.

----



At 200 ISO there is a little noise visible, but it's not too serious.

----



At 400 ISO the noise is unmistakeable.

----



At 800 ISO the image noise is now quite bad.

----



A 1/3EV increase to the maximum 1000 ISO shows serious image noise, with a lot of fine detail being obscured.

This is the full-frame image at 1000 ISO.
