Dear Bros

In DPP, there is a new function Unsharp mask. There are 3 parameters
Strength, Fineness, Threshold
How do they affecting each others?

You can completely apply the concept of using unsharp mask in photoshop to it.
　
Strength=Amount
Fineness=Radius
Threshold=Threshold

They are just the same. If u are not familiar with that feature in photoshop. You may take a look at the page below or google it.
