>It would probably be better to convert to JPG first and then sharpen. Theoretically maybe; but out of curiosity, how does one do this in actuality when one would have to first decompress the JPG file before one could carry out the sharpening operations. Afterwhich, one would then recompress the file again in its altered state which would be what typically causes the artifacts and deterioration in JPG files to begin with?

Speaking of sharpening - I think I understand this in a sort of sloppy "intuitive" way, but could someone offer a technical explanation of why sharpening has so much more visible effect on jpegs as opposed to TIFFs?
