Align objects on different layers
You can align the content of layers and groups using the Move tool . (See Move the content of layers.)
1. Do one of the following:
To align multiple layers, select the layers with the Move tool or in the Layers panel, or select a group.
To align the content of one or more layers to a selection border, make a selection in the image, and then select the layers in the Layers
panel. Use this method to align to any specified point in the image.
2. Choose Layer > Align or Layer > Align Layers To Selection, and choose a command from the submenu. These same commands are
available as Alignment buttons in the Move tool options bar.
Top Edges Aligns the top pixel on the selected layers to the topmost pixel on all selected layers, or to the top edge of the selection
border.
Vertical Centers Aligns the vertical center pixel on each selected layers to the vertical center pixel of all the selected layers, or to the
vertical center of the selection border.
Bottom Edges Aligns the bottom pixel on the selected layers to the bottommost pixel on selected layers, or to the bottom edge of the
selection border.
Left Edges Aligns the left pixel on the selected layers to the left pixel on the leftmost layer, or to the left edge of the selection border.
Horizontal Centers Aligns the horizontal center pixel on the selected layers to the horizontal center pixel of all the selected layers, or to
the horizontal center of the selection border.
Right Edges Aligns the right pixel on the linked layers to the rightmost pixel on all selected layers, or to the right edge of the selection
border.
Distribute layers and groups evenly
1. Select three or more layers.
2. Choose Layer > Distribute and choose a command. Alternatively, select the Move tool and click a distribution button in the options bar.
Top Edges Spaces the layers evenly, starting from the top pixel of each layer.
Vertical Centers Spaces the layers evenly, starting from the vertical center pixel of each layer.
Bottom Edges Spaces the layers evenly, starting from the bottom pixel of each layer.
Left Edges Spaces the layers evenly, starting from the left pixel of each layer.
Horizontal Centers Spaces the layers evenly, starting from the horizontal center of each layer.
Right Edges Spaces the layers evenly, starting from the right pixel on each layer.
Automatically align image layers
The Auto-Align Layers command can automatically align layers based on similar content in different layers, such as corners and edges. You
assign one layer as a reference layer, or let Photoshop automatically choose the reference layer. Other layers are aligned to the reference layer
so that matching content overlays itself.
Using the Auto-Align Layers command, you can combine images in several ways:
Replace or delete parts of images that have the same background. After aligning the images, use masking or blending effects to combine
parts of each image into one image.
Stitch images together that share overlapping content.
