To repeat a copy and transformation in Photoshop, use the following keyboard shortcut after initially duplicating and transforming your selection: Ctrl + Alt + Shift + T (Windows) or Cmd + Option + Shift + T (Mac).
Here's a breakdown of the process and how it works:
1. Initial Copy and Transformation:
- Select the layer or object you want to copy.
- Duplicate the selection. You can do this by:
- Dragging the layer to the "Create a new layer" icon (looks like a plus sign) at the bottom of the Layers panel.
- Using the keyboard shortcut: Ctrl + J (Windows) or Cmd + J (Mac).
- Transform the duplicated layer. Go to Edit > Transform, and choose a transformation option (e.g., Scale, Rotate, Skew, Distort, Perspective).
- Apply the transformation as desired.
2. Repeating the Transformation:
- After applying the initial transformation, use the "Transform Again" command with copy. Use the shortcut Ctrl + Alt + Shift + T (Windows) or Cmd + Option + Shift + T (Mac).
- Photoshop will create a new layer, duplicate the previous one, and apply the exact same transformation again (scaling, rotation, position shift, etc.).
- You can repeat this step as many times as needed to create a series of duplicated and transformed objects. Each time you press the shortcut, a new layer is created.
Example:
Let's say you want to create a circular pattern of stars:
- Create a star shape on a new layer.
- Duplicate the star layer (Ctrl/Cmd + J).
- Rotate the duplicated star slightly (Edit > Transform > Rotate).
- Now, press Ctrl + Alt + Shift + T (Windows) or Cmd + Option + Shift + T (Mac) repeatedly. Each press will create a new star, rotated the same amount as the first duplicate, resulting in a circular pattern.
Important Considerations:
-
New Layers: The "Transform Again" command with copy creates a new layer for each repetition. Be mindful of the number of layers you create, as too many layers can impact performance.
-
Raster vs. Vector: This technique works effectively with both raster and vector layers. If you are using Shape layers in Photoshop, make sure the "Create Vector Mask" option is selected, and you'll continue to have vector shapes after the transformation.
-
Alternatives: For complex patterns, consider using Photoshop's Pattern tools or creating a custom brush.
