Basic sharpening techniques in Photoshop CS5 create unnecessary noise in midtone sections. This Sharpening procedure creates stunning high definition images on press while reducing unwanted image noise.
• Now the sharpening amount, 4:07, in Unsharp Mask, is how much the adjoining pixels are affected. I like to go real high on this number, anywhere between 150 and 200.
