Photoshop Tutorials: Add A Realistic Water Reflection

Step 3: Flip The Top Layer Vertically

In order to create our reflection, we need to flip our image upside down, so let's do that.

With the top layer selected in the Layers palette, go up to the Edit menu at the top of the screen, choose Transform, and then choose Flip Vertical.

Photoshop will flip the image upside down in the document:

Step 4: Drag The Flipped Image To The Bottom Of The Document

We need the flipped image to be at the bottom of the document, so grab your Move Tool from the Tools palette, or press V on your keyboard for the shortcut:

Then, with the Move Tool selected, click inside the document and drag the flipped image down to the bottom until the top of it is lined up with the bottom of the original image above it. Hold down Shift as you drag to make sure you drag down in a straight line:

Step 5: Add A New Blank Layer

Now that we have our flipped image in place, we can begin to create our water ripple effect. First, we need to add a new blank layer at the top of the Layers palette, so with "Layer 1" still selected, click on the New Layer icon at the bottom of the Layers palette:

Step 6: Fill The New Layer With White

We're going to fill our new blank layer with white. If white is not currently your Background color, press D on your keyboard, which will reset Photoshop's Foreground and Background colors, making black your Foreground color and white your Background color. Then use the keyboard shortcut Ctrl+Backspace (Win) / Command+Delete (Mac) to fill the new layer with the Background color (white). Your document will be filled with solid white.

Step 7: Apply The "Halftone Pattern" Filter To Create Black And White Horizontal Lines

Go up to the Filter menu at the top of the screen, choose Sketch, and then choose Halftone Pattern. This brings up Photoshop's Filter Gallery (in Photoshop CS and higher) set to the "Halftone Pattern" filter options on the right, with a large preview of the effect on the left. We're going to use this filter to add a series of black and white horizontal lines to the image. These lines are going to become our water ripples . The more lines we have, the more ripples we'll have. First, we want to make sure we're creating lines and not dots or circles, so set the Pattern Type option to Lines. We control the number of lines by adjusting the Size option. Lower values give us more lines, since we're lowering the size of each line, and higher values give us fewer but thicker lines. I'm going to set my Size value to 7, which I think works best for my image. You may want to experiment with this value on your own. The Contrast option below it determines how sharp the edges of the lines are. Lower values give you softer lines, white higher values give you hard edge lines. Set this value all the way to 50 to give your lines sharp edges. We're going to soften them ourselves with the Gaussian Blur filter in a moment:

Click OK when you're done to exit out of the dialog box, and Photoshop will fill the image from top to bottom with your black and white lines:
