More Unsharp Masking

The image on the left is an actual illustration of unsharp masking at a magnification you might need to use. The area to the right of the dots has unsharp masking applied. You might notice the black dots scattered around - these are known as artifacts (in the trade). You might not want see your pictures liberally laced with black spots. I admit you will need to be making a very large print but even at small magnifications these spots will appear. The image on the left is not much of an exageration - so be vey careful.
