Image parameters (contd.)

Sharpening adjustment

Even putting aside for a moment the fact that the S5 Pro's 12MP output is interpolated up from 6MP (and therefore can't be expected to be razor-sharp viewed at 100%) there's no getting over the fact that the default settings produce output that looks very soft indeed close up, even if you drop down to 6MP. You can turn up the sharpening slightly, but don't expect this to suddenly transform the S5 Pro's output into something crisp and detailed (especially at 12MP). If you try to sharpen too much in post-processing you risk making the interpolation and noise artefacts too visible. We found the best results to be had were from careful unsharp masking of 6MP JPEGs.

Tone (contrast) adjustment

Adjusting the tone alters the shape of the 'S curve' (gamma curve) used to map the linear image data captured by the sensor into the correct gamma. A lower contrast setting maintains more of the original data's dynamic range but leads to a flatter looking image. A higher contrast setting stretches the grayscale (dark to light) of the image and could lead to clipping of both shadow detail and highlights. Again we felt that the range of settings on offer was too narrow, with too little effect on the final image. If you thought the range of sharpening offered in-camera was limited then look at the examples below: the differences between the various settings really are very subtle.
