about the picture of the old man in tutorial "unsharp mask"

I seem to have trouble when trying to tune the amount, radius and threshold parameters in Photoshop CS2 Unsharp Mask to get the same "sharpened" result as shown in the tutorial http://www.cambridgeincolour.com/tut...sharp-mask.htm.

Could it be possible that the "sharpened" version is really the original picture, and that the "original" version is a blurred one from that? because I highly doubt that the fine texture on his clothes could be recovered from the blury version.

or could someone here post a set of parameters for Photoshop CS2 Unsharp Mask to achieve that ?

Re: about the picture of the old man in tutorial "unsharp mask"

Sorry for any confusion; this example did not intend for the viewer to try and replicate the steps using the softer online image. This is primarily because sharpening was not applied to the online JPEG, but was instead applied to a more detailed TIFF (which was then compressed to show the online JPEG). Trying to sharpen the JPEG will make compression artifacts much worse, and will not bring out anywhere near as much detail.

I have updated these images to include an unsharpened JPEG that makes the process more replicable. Give it a try. The unsharp mask settings for the result you see are 400%/0.2/0 for the amount/radius/threshold.
