Canon PowerShot A490 - 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 minimum ISO.


Image quality at 80 ISO is pretty good.


There is a trace of colour mottling even at 100 ISO.


Noise is clearly visible at 200 ISO.


Noise reduction has removed some of the chromatic noise at 400 ISO, but the image still have luminance noise.


Noise reduction has reduce image quality at 800 ISO.
