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.

----


There's no discernable difference at 100 ISO.

Pushing up to 200 ISO and the IXUS 90 IS still produces clean and detailed images.

----


At 400 ISO some noise begins to creep in, but the result is still very respectable.

----


Things start to go south at 800 ISO, with noticable noise and loss of detail.

----


At 1600 ISO the DIGIC III processor just can't cope with the amount of CCD noise intruding on the image. Detail is completely lost in low intensity areas, and the colour fidelity suffers considerably.
