Go up to the Filter menu at the top of the screen, choose Sketch, and then choose Halftone Pattern.

This tells Photoshop not to place any of the extra canvas space above the document and instead to place all of it at the bottom: Click inside the square in the middle of the top row (again as circled below). This is where we tell Photoshop where we want to place our additional canvas space. Below the "Relative" option is a 3x3 grid of squares. Then make sure the Relative option is checked, which tells Photoshop to give us 100% more canvas space than what we already have. The easiest thing to do here is to add twice as much canvas space as what we currently have, but we only want it to appear at the bottom of the document, not above it or on either side, so we need to tell Photoshop exactly where we want this extra canvas space to go.įirst, enter 100 for the Height and set the measurement to percent, as circled in red below. This will bring up Photoshop's "Canvas Size" dialog box. To do that, go up to the Image menu at the top of the screen and choose Canvas Size. We're going to add our water reflection below the image, so let's add some canvas space to the bottom of our document to make room for our reflection. Step 2: Add More Canvas Space To The Bottom Of The Document Press "Ctrl+J" (Win) / "Command+J" (Mac) to duplicate the Background layer.
