Casio Exilim EX-Z25 - 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 shaded natural light.

----



This is the full frame at 64 ISO.

----



At minimum ISO the image quality is very good, with smooth colour and no visible noise.

----



Much the same result at 100 ISO.

----



Still no problems at 200 ISO.

----



Image quality is still good at 400 ISO, not bad for a cheap 12MP compact.

----



At 800 ISO however there is a lot of noise and loss of detail.

----



1600 ISO is also very noisy, but at least the colour rendition is good.

----



The full frame at 1600 ISO.
