Nikon Coolpix S6700 Review

July 17, 2014 | Matt Grayson | |

Image Quality

All of the sample images in this review were taken using the 20 megapixel Fine JPEG setting, which gives an average image size of around 7Mb.

Noise

Low ISO settings are understandably good quality with no obvious noise becoming apparent. The Nikon Coolpix S6700 has an ISO 80 setting as well as ISO 100. That's only around a third of a stop difference and when it comes to the crunch, which won't make much difference to your exposure.

Things seem pretty quiet until ISO 200 where there seems to be a degree of sharpening in dark areas as though noise reduction is playing around with the settings. There  looks to be very small amounts of blue noise coming through, but we can't be sure. However, skipping to ISO 400 confirms that we were seeing it as bright blue spots begin to appear. Detail starts to dissipate in the darker areas, but midtones still look good.

At ISO 800, it looks as though the camera has got things under control as noise levels seem to go back to ISO 200 levels. Colours that are supposed to be on the picture aren't suppressed, though and edges look surprisingly sharp. At ISO 1600, the noise has returned but is still better than what we expect to see at this setting. The final setting is ISO 3200 and the S6700 uses a lower resolution in order to reduce on certain types of noise that are created by heat from neighbouring pixels. The further away from each other they are, the less they affect each other. Aside from some sporadic bright blue spots, the picture looks ok.

Sharpening

Adding sharpening to the pictures after you've taken them via an editing suite is acceptable enough and the pictures look good. If the ISO is too high, the pictures will look worse, though so only add sharpening if the sensitivity is around ISO 100 or ISO 200.

File Quality

There are two 20 megapixel settings on the Nikon Coolpix S6700. The one with the star is the Fine compression setting and the one without is the Normal compression. I Fine, a typical picture is around 7.5Mb while in Normal it's around 4.2Mb. The amount of pixels remains the same in these settings, but the camera will lose data as it saves to the memory card. This can result in fine detail areas with less detail, but the Normal setting does release a lot of extra space on the memory card.

Normal (4.18Mb) (100% Crop)

Chromatic Aberrations

Chromatic aberration isn't forth coming on the Nikon Coolpix S6700. In fact, we had a hard time finding any at all.

Macro

Close focusing on the Nikon Coolpix S6700 is around 5cm at wide-angle which is by no means the best results that you can get even at this price point. Pictures are very sharp in the centre sweet spot, though. When image quality does drop off, it's not by too much either.

Flash

There's an ever-so-small amount of vignetting that occurs in the corners of the frame. It doesn't matter where the zoom is or whether the flash is on or off, it appears. Using flash does make it more prominent, though.

We didn't have any problems with red-eye in our test shots, so we couldn't effectively test the red-eye reduction features of the S6700. Red-eye is handled via the red-eye reduction feature in the flash settings.

Night

There are two Night scene settings on the Nikon Coolpix S6700. You can select from either Hand-held or tripod. The latter lowers the ISO to increase the quality of the image as it can use a slower shutter speed. The camera did just that and went down to ISO 80 compared to the ISO 800 in Hand-held mode. It matches the settings in Auto mode, with the exception that it's limited to 1sec exposures, whereas the Night scene mode can go to 2sec to get a better exposure.
