Processing manipulation

Nikon Coolpix S31 is different from most of other compact cameras, in which there’re4 buttons on the left of the screen – they’re used to control most of the options. Zoom control is on the right, with on / off button sitting on the top of the page and easy to use shooting and video-recording starting button sitting on both sides. The menus are created from large and audacious texts, icons are full of colors, with the options selected by using 4 buttons on the left of the camera.

The images in general is well exposed, under-water effect is also good. The skin tone is OK when shooting portrait, but red-eye appears obviously when using flash.

Lens quality

Testing images from the lens

Testing images from the lens

Images have some pretty detailed ones at both ends of the lens for a budget-limited camera, as well as a better purple border control. The lens has min focusing distance 5cm, which allows you to have close enough distance for good macro shooting.

ISO image noise level

ISO testing image

ISO testing image

It’s harder than normal when attempting to check the camera noise performance, as the camera don’t allow you to choose the ISO settings. this means that we have to change the light in the room to force the camera changing ISO settings. noise level is low at ISO 80 and 125, with the pretty sharp remaining images at ISO 250. In our testing image, you can see noise level making the images become soft, with some lost details.

White balance effect

The same to any other cameras that lack white balance setting, so instead of us simply changing the light sources an leaving the camera on auto setting. This camera performs pretty well on both tungsten and incandescent settings.
