Example: Changing the Amount Variable

When experimenting, change only one variable at a time.

Below, the amount setting of Unsharp Mask Sharpening was changed from 100% to 400%.

Original	Unsharp Mask Sharpening Amount: 100% Radius: 1 Pixels Threshold: 2 Levels	Unsharp Mask Sharpening Amount: 100% Radius: 1 Pixels Threshold: 2 Levels

The sharpening with an amount of 100% added gray lines on either side of the edge between the two gray boxes.

Changing the amount from 100% to 400% changed the gray lines to lines that are more black and white.

You can see the change more clearly below.
