The Coollpix 5700's Auto white balance produced perfect results under natural light and also put in a good effort under artificial lighting (certainly better than it's brother the Coolpix 4500). The pre-programmed white balance presets also seemed to work well and of course have the flexibility to be tuned to match your regular light sources. Manual preset white balance was very good and produced virtually identical results under a variety of light sources. Overall a good performance.

White Balance fine tuning
White Balance fine tuning is a feature which has been available on prosumer level Coolpix digital cameras and Nikon D-SLR's for some time. It allows you to tune the built-in white balance presets by up to 3 levels plus (cooler - blue) or minus (warmer - red) the default. In the example below you can see that under an Incandescent studio lamp the Incandescent +3 setting produces a near perfect color response.

The Coolpix 5700 uses the same method as other Coolpix digital cameras to indicate the macro 'sweet spot', it does so by turning the macro indicator yellow when the camera zoom is within the optimum range (best frame coverage vs. subject distance). This range appears to be from approximately quarter zoom (53 mm equiv.) to three quarters zoom (107 mm equiv.)
We found the best frame coverage to be at the telephoto end of this range, at 107 mm equiv. (27.3 mm native focal length). At this position frame coverage is approximate 30 mm (1.2 in). Good considering the 8x zoom lens, unfortunately the corners of the frame are fairly soft.

The Coolpix 5700's pop-up flash has a specified range of 4.0 m (13.1 ft) at wide angle and 2.8 m (9.2 ft) at telephoto. Just like the Coolpix 4500 we found that the Coolpix 5700 was slightly conservative about its flash power output, luckily the 5700 does allow you to compensate flash power output by +/-2.0 EV in 0.3 EV steps.
|Skin tone test: Good colour, no cast, conservative metering and flash power.||As noted above, a good exposure with some drop off in the bottom corners.||Color patch test: Good exposure, well metered with good colour.|
The Coolpix 5700 also has a flash hotshoe (ISO, X-contact only) to which you can attach Nikon Speedlights 80DX, 50DX, 30, 28DX, 28, 26, 25, 24, and 22s. You can also use other accessories for off camera flash or studio flash trigger. The 5700 does not have a two way communications path with external Speedlights and thus does not support flash zoom, flash AF assist etc. Because of this the internal flash must be popped up so that the camera's photocell can measure the flash output of the external flash.
Night exposures / Noise reduction
The 5700 has the same noise reduction system seen in other prosumer Coolpix digital cameras. When enabled this feature will automatically remove noise from images which have a shutter speed of 1/15 sec or slower. For long exposures this means a second 'dark frame' exposure immediately after the first shot. This dark frame is used to subtract hot pixel noises from the first exposure. The slowest available timed shutter speed is eight seconds, however you can take Bulb exposures up to five minutes (optional USB remote recommended).
