Step 50

Set foreground color to black and Brush Opacity, which can be found in the Options Bar, to 50%. Paint on the piece's edge to hide it and reveal the original we had earlier. That original shape is going to be the paper color.

Step 51

Do the same to the next piece.

Step 52

Keep on doing this to the other pieces.

Step 53

Here's the result to the rest of the pieces.

Step 54: Adding Shadows

We have added shadow to each piece using its own layer style setting in the shape of Drop Shadow. But, it's not enough. To fix it, we need to paint the shadows manually. Activate the Brush Tool and select brush type with soft edges.

Step 55

We also want to paint the shadow in its own layer. The shadow layer should be at the bottom of all the layers and one step above the Background layer. Using the Brush Tool, carefully draw a big shadow at first.

Step 56

And then delete unneeded shadow using the Eraser Tool. Hit 1 from the keyboard to decrease the Eraser's Opacity to 10% to help you erase the shadows gradually. Use greater Opacity for faster result.

Step 57

Paint smaller and darker shadow right underneath some of the piece's edge. Use the Brush Tool with smaller brush tip and higher Opacity setting.

Step 58

Let's take a look at the result when an actual photo is added. Double click the Linked Smart Object that we put at the top of all layers.

Step 59

The guide file will be opened in Photoshop in a separate window. Anything we do to this file will be reflected back to the mockup file. Let's take an image from unsplash.com and paste it on top, covering the multi-colored rectangles. When this mockup is finished and functional, we no longer need those rectangles and can get rid of it. But for now, we'll just leave it be.

Step 60

Save the guide file that we have updated and then close it. Photoshop will automatically update the Linked Smart Object layer. This might take a while depending on your machine and the file size. Be patient. Once everything is clear, you will no longer see pieces of multi-colored rectangles but a torn photo.

Step 61

To change the paper color, double click thumbnail of the basic shapes layer. A Color Picker dialog box will pop up. Select new color and click OK button to confirm new color.
