1. Masking in Photoshop What is It? How does It work?

2. There is a Clipping Mask? A clipping mask lets you use the content of a layer to mask the layers above it. The masking is determined by the content of the bottom or base layer. The non-transparent content of the base layer clips (reveals) the content of the layers above it in the clipping mask. All other content in the clipped layers is masked out. Just like our Image Within Type

3. 1. Arrange the layers in the Layers panel so that the base layer with the mask is below the layers that you want to mask. 2. Do one of the following: Hold down Alt (Windows) or Option (Mac OS), position the pointer over the line in the Layers panel dividing the base layer and the first layer above it that you want to include in the clipping mask (the pointer changes to two overlapping circles ), and click. Select the first layer above the base layer in the Layers panel, and choose Layer > Create Clipping Mask. 3. To add additional layers to the clipping mask, use either method in step 2, and work your way upward one level at a time in the Layers panel. Create a clipping mask
