Maybe my fault, but the result of the Filter Unsharp Mask is not the same you see in the preview of the filter after a resample crop.
1. I cropped the image a bit (resample). Additional question: Why do we have no option for the resample methode like Bicubic, Bilinear, Nearest Neighbor etc.?
2. I opened Filter Unsharp Mask and preview was showing what I wanted.
3. After hitting "Apply" the result had nothing in common with the preview.
