| Why is it called Unsharp mask, if we use it to sharpen our photos? I have had this question in my mind but haven't asked anyone or looked it up yet. Anyone know? |

It all goes back to the days of darkroom printing. I remember my photography professor teaching us how to do this with all the chemicals and paper and negatives and ... whew! those were the days!
From Wikipedia:
The "unsharp" of the name derives from the fact that the technique uses a blurred, or "unsharp", positive to create a "mask" of the original image. The unsharped mask is then combined with the negative, creating the illusion that the resulting image is sharper than the original.

| hmmm, I always thought it just meant if you were wearing an 'unsharp mask', you didn't have to worry about getting cut. |
