With the arrival of Smart Sharpen in CS2, some Photoshop experts predicted the death of the Unsharp Mask filter. Despite their predictions, there are practical uses for both tools when working in print design and production. You will find that both tools work well with a wide range of images:
- For images where you would like to control the effect of sharpening based on contrast, you will find that the Unsharp Mask tool is still very useful.
- In those images where you have critical highlight and shadow values, and particularly those where you want to apply a large amount of sharpening, the Smart Sharpen tool is unparalleled!
- When the sharpening demands are increased, and you want to more precisely control the location of sharpening in your image, you can use some tried and true edge-recognition and enhancement techniques to help you control your sharpening.
- And then of course there are the sharpening functions (Sharpen and Preserve Details) found in the Reduce Noise filter, that you might use in conjunction with a noise reduction process. This is a handy tool to use when you are smoothing images, and in images without critical highlights or shadows and/or without special sharpening needs. With images that do not have critical sharpening requirements, you will likely find the Reduce Noise detail enhancement/sharpening controls adequate, or at least useful enough to provide you with a good first step. You can always start with the Reduce Noise sharpening functions and fine-tune later by using either Unsharp Mask or Smart Sharpen. Let’s go through a few sharpening examples to see how to use the various sharpening specific tools and techniques.
