Canon PowerShot G9 - 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 and maximum ISO settings have been reduced to let you see the full image, and a series of full resolution crops have taken from original images at a range of ISO settings to show the overall image quality.



We're back with the Jag this week, since the metallic paint on the Aston was causing problems. This is the full frame at 80 ISO.



At the minimum ISO setting of 80, the image quality is fantastic.



It's not too visible on this shot, but at 100 ISO there is some noise in the darker areas.



At 200 ISO there is visible noise in all the darker areas, and the colour is looking a bit faded and blotchy.



Image noise is a lot more noticeable at 400 ISO.



Worse still at 800 ISO.



At 1600 ISO the image quality is about as bad as any other 12MP compact.



This is the full frame at 1600 ISO.
