Controlling sharpness in an image (or specific areas of an image) is extremely important. One of my favorite bloggers, Veerle, has a new tutorial for people who want to try out sharpening with the Smart Filter feature in Photoshop CS3. It is simple and clearly written. If you haven’t tried out Smart Filters, this is a good introduction to it. For other tutorials on this topic, look at How to Apply a Smart Filter in Photoshop CS3 by Steve Patterson. Al Ward gives you Adobe Photoshop CS3: A Filter-Freak’s Dream for a more involved sharpening effect. If you prefer learning from a video tutorial, try watching Michael Ninness’ tutorial called, “Applying Smart Filters.” Matt Kloskowski has some cool tips on using Smart Filters on his Photoshop Killer Tips site. Check out his Dragging Smart Filters.
