Correcting Specific Areas
Making corrections to the entire image is often essential. Sometimes, though, only a portion of the image needs to be sharpened or have noise reduced. To correct only a portion of the image, you can use a layer mask.
If you're working with an adjustment layer, a layer mask is built in. To adjust a masked area:
- Use any selection tool to select the part of the image you want to affect.
- Select the adjustment icon in the Adjustments panel to create a new adjustment layer. Photoshop creates a mask that protects the unselected area in the layer.
- Make the adjustments.
)
Figure 4.27 When you add an adjustment layer, Photoshop automatically creates a layer mask for it.
If you want to apply sharpening or noise reduction to a specific area of the image, first create a new layer.
- Use a selection tool to select the area you want to affect.
- If the content includes multiple layers, choose Edit > Copy Merged to copy all the visible content in the selection onto a single layer. (If you're working with only a single layer, you can choose Edit > Copy.)
- Choose Edit > Paste to create a new layer.
- Select the new layer and apply the sharpening, noise reduction, or other enhancement.
