Sharpen – Use this option to sharpen lines that may be fuzzy or not clean in the original image.
Sharpen More – Use this option when you want to sharpen the image more than the standard Sharpen
filter does.
Blur – Use this option when you want to soften the edges of an image.
Blur More – Use this option when you want to soften the edges more than the Blur filter does.
