Nikon Coolpix P90 - 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 ISO test images are shot indoors using reflected natural light for maximum consistency.

This is the full frame at 64 ISO.

At 64 ISO the image is clean and sharp, although there is some noise visible in the darker red area.

----



There is a little colour mottling in the green area at 100 ISO, but it's not enough to worry about.

----



Better results at 200 at the noise reduction kicks in.

----



There is some loss of fine detail at 400 ISO, but image quality is still good.

----



Colour is starting to break up at 800 ISO, but the image is printable.

----



Quite a lot of noise at 1600 ISO, and not much fine detail is left.

----



3200 ISO is available at 3MP, but image quality is poor.

----



It's worse still at 6400 ISO.

This is the full frame at 6400 ISO.
