In GIMP the default values for unsharp mask are far far too high. In Photoshop I used to convert an image to LAB mode and then sharpen the luminance channel only. I made an action for this and it was just a matter of pressing a keyboard shortcut. I found that small amounts of sharpening, say 50% (I think my units are correct from memory) possibly applied two or three times were better than a larger amount applied once and if you'd gone too far it was an easy matter to go back one step in history to obtain an optimum amount of sharpening. It's possible to do it in LAB mode in GIMP but you can't save it as an action so it becomes a tedious procedure.The processing time per image is much shorter than the time it's taken me to write this response.BarriePS That image was somewhat aided by being taken on a misty day so the far background is softer to start with.B.</blockquote>
