Casio Exilim EX-Z550 - 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. These pictures were taken indoors using reflected natural light
