Canon Digital IXUS 950 IS - 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.

As is nearly always the case, image quality at 80 ISO is superb.

----



Not surprisingly there's little difference at 100 ISO.

----



At 200 ISO however there is some chromatic noise visible in the darker areas.

----



It's a little worse at 400 ISO.

----



And worse still at 800 ISO, although there is still plenty of fine detail visible and the shot would print well.

----



1600 ISO is a lot worse, and most fine detail has been lost.
