Noise reduction and sharpening

Instead of pixel peeping at 100% to judge sharpening I look at water and metal objects the deconvolution algorithms make both look more realistic sometimes astonishling so, but that is a very subjective opinion, worth the experiment

I've tried FocusMagic, which is a deconvolution application, and found it difficult to control, with results more often than not too crunchy for my taste. I think this kind of program is not ideal for enhancing acutance. Where it does have merit, however, is in reconstructing seriously out of focus detail. For example, the letters and numbers on a license plate of a car parked up the street were small and unreadable before deconvolution, but quite distinguishable after.
