Version: 1.1.0 (using KDE 4.3.2) OS: Linux Installed from: Ubuntu Packages Using unsharp masking can lead to solarisation-like artifacts in near-black or near-white areas. Use unsharp masking. If necessary, apply several times to achieve the effect or make it more visible. Look at areas that were near-black or near-white before sharpening. They should tend even more towards the extreme now, at least at their borders. Instead, where one would expect the result to be whiter than white, you will find a dark area and vice versa. So even the slightest sharpening of an image which uses all the available tonal range will damage highlights and shadows.
