Image Processing Adjustments

Just like the recently reviewed Coolpix 4500 the 5700 provides control over three different parameters associated with the cameras internal 'post-shot' image processing algorithms. However unlike the 4500 the parameters associated with each setting are closer to the 5000. These are Tone (labelled 'Image Adjustment'), Saturation (Colour) and Sharpening. Each of these three parameters can be set independently to best suit your preferred 'look' or the type of shot.

Image Adjustment (Tone)

Auto Normal More Contrast
Less Contrast Lighten Image Darken Image

In this example the Auto setting seemed to choose the Normal tone curve, as we'd expect 'More Contrast' does just that and produces a much punchier higher contrast image. As we've seen on other Coolpix digital cameras is the appearance of a 'Less Contrast' image which not seems to not only reduce the image contrast but also its brightness. In my opinion 'Image Adjustment' should be renamed to 'Tone' or 'Contrast' and the 'Less Contrast' option should be re-labelled.

Saturation Control (Color)

On the 5700 you have one positive and two negative levels of color saturation adjustment above and below 'Normal'.

Maximum (+1) Normal (0) Moderate (-1)
Minimum (-2) Black & White  


The Coolpix 5700 provides four selectable sharpening levels as well as the 'Auto' setting which will analyse image detail and automatically choose the most appropriate level of sharpening.


'Clear Image Mode' Noise Reduction

We first saw the 'Clear Image Mode' option (SXGA or lower only) on the Coolpix 5000, it's intended to "Minimizes noise and improves color gradation in SXGA or smaller size images." (from the 5700 manual). In this mode the camera takes three exposures, two with the shutter open and one with it closed. It uses these three images to compare noise and produce the final image. What I've never understood is that this option doesn't appear to improve anything and only serves to destroy vertical resolution. Very strange.
