How Do I Make a Shape Guide in Photoshop?

To create a shape guide in Photoshop, use the shape tool to draw a shape, and then convert the shape to a guide.

Here's a breakdown of the process:

1. Select a Shape Tool: Choose a shape tool (e.g., Rectangle Tool, Ellipse Tool) from the toolbar. It doesn't matter what color the shape is initially.
2. Draw Your Shape: Click and drag on the canvas to draw the desired shape.
3. Convert to Guides: Unfortunately, the reference doesn't describe the exact steps of converting the shape into a guide. Generally, you would have to right-click on the layer in the layers panel that corresponds to the shape, and rasterize the layer. Then, you can select the pixels you want to turn into a guide by using for example the magic wand tool, and after selecting the pixels, go to View > New Guide.
