Sony Cyber-shot DSC-W290 - 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

This is the full frame at 80 ISO.

Although the image quality is very good, there is a slight grain right across the image. Unfortunately it doesn't show up as much in this compressed JPEG. The white dots are dust on the model, not from the camera.

----



Slightly more grainy at 100 ISO, but no real noise problems.

----



Still good quality at 200 ISO.

----



400 ISO is usually make-or-break for image noise, but the W290 is still doing well.

----



Noise is starting to be an issue at 800 ISO.

----



1600 ISO and a lot of darker detail has been lost to noise.

----



Image quality is poor at 3200 ISO, but the colour balance and saturation remains quite good.

This is the full frame at 3200 ISO.
