Photoshop includes several tools you can use to correct your images. In this lesson, we’ll show you how to make the following corrections:

• Sharpening: If an image is less clear than you’d like it to be, you can sharpen it.
• Noise reduction: If an image has a lot of noise, or graininess, you can reduce the image noise.

We’ll also cover the importance of using these tools correctly. If they are misused, sharpening and noise reduction can actually cause problems. If they are used with care, they’re a great way to add polish to your images.
