Sony Cyber-shot DSC-H9 - Test shots - ISO performance

A range of test shots are shown over the next few pages. Here, the full size images at the minimum and maximum ISO settings have been reduced for bandwidth purposes to let you see the full image, and a series of crops taken from original full resolution images at a range of ISO settings have been included in order for you to gain an appreciation of the overall quality.



This is the full frame at minimum ISO.



Although there is no noise, there are other problems with the image quality.



At 200 ISO there is some colour mottling in the darker areas.



At 400 ISO the noise reduction system is already erasing fine detail.



Image noise is greatly increased at 800 ISO.



At 1600 ISO there is no fine detail left, and the image quality is very poor.



Never, ever use this setting. 3200 ISO, but for what?



This is the full frame at 3200 ISO.
