Just about every image that is brought into Photoshop, whether from a scanner, digital camera, CD-ROM, etc., needs to be sharpened. The undisputed tool for this task is Photoshop’s Unsharp Mask filter. The only downside of using this filter is that getting the level of sharpening you’d like can sometimes cause color shifts and halos, and it can also accentuate dust or specs within the image. There are two ways around this, and what’s great about these methods is they let you apply a higher level of sharpening without causing color shifts or other problems: (1) Convert your file from RGB mode to Lab Color. Then go to the Channels palette and click on the Lightness channel. Now apply the Unsharp Mask filter (twice if you need it), then switch back to RGB mode (don’t worry, there’s no harm in this RGB-to-Lab-to-RGB mode conversion). (2) If you’re working on a CMYK image, apply the Unsharp Mask filter, then go under the Edit menu and choose Fade Unsharp Mask. When the Fade dialog appears, change the Mode pop-up menu to Luminosity and click OK (which pretty much does the same thing as method 1; it applies the sharpening to the luminance of the image, not the color).

Corey shares another way to get a cool 3D light beam effect.
Corey finishes up the Olympic-inspired design that he began last week in Part 1.
The Olympic-inspired tutorial will be coming in two parts. Stop by next week for the conclusion to this video.
This week’s tutorial deals with creating masks for complicated images by using channels.
While working in the Vanishing Point filter, you can create a multi-plane grid and return the part of the image contained in the grid back to Photoshop as a 3D layer (choose Return 3D Layer to Photoshop from the flyout menu). Once it is a 3D layer, you can move the object around in three dimensions using Photoshop’s 3D tools.
