How do you reverse a canvas in Photoshop?

You can reverse a canvas in Photoshop, also known as flipping or mirroring it, using two main methods.

Flipping the Entire Canvas

You can flip the entire canvas using the following steps:

1. Go to the Image menu at the top of the screen.
2. Select Image Rotation.
3. Choose either:
   • Flip Canvas Horizontal to flip the canvas left to right.
   • Flip Canvas Vertical to flip the canvas top to bottom.

Flipping Individual Layers

Sometimes, you may only want to flip certain parts of your image, not the entire canvas. To do this:

1. Select the layer you want to flip in the Layers panel.
2. Go to the Edit menu.
3. Navigate to Transform.
4. Choose either:
   • Flip Horizontal to flip the layer left to right.
   • Flip Vertical to flip the layer top to bottom.
