HOW TO CREATE THE 3D POP OUT EFFECT IN PHOTOSHOP: AKA OUT OF BOUNDS EFFECT

STEP 1, CUT OUT THE SCREEN

Choose the Polygon Lasso tool

The four corners of the screen should all be clicked. You can identify the start and end points by the circle on the last corner.

Your choices will be finished after you click.

You will see the marching ants selection is active,

Notice, the hand is overlapping. We need to fix it.

Choose the Quick Selection tool

To put it in negative or subtractive mode, hold down Alt or Option. The centre of the cursor’s + will change to a – as you can see.

To remove the area, drag it.

The tool will make the choice after you have applied it.

Wait while we add a layer mask to remove the selection.

Holding down Alt or Option while clicking the layer mask button will enable us to conceal the specified area.

We have transparency on the screen. Perfect!

STEP 2: CUT OUT THE SUBJECT FROM THE BACKGROUND

FILL OUT THE SAME DOCUMENT WITH THE TWO IMAGES.
Having an area that will protrude beyond the screen once the backdrop has been removed is crucial when choosing a picture to be extruded.

Select File > Open.

Drag the image into the tab of the image that includes the screen using the move tool (v). (How to use Photoshop to merge photos)

Hold on tight because the second image will soon appear. Release the mouse button after moving the cursor to the centre of the image (or lift the pen if using a tablet).

You will see the 2 layers on the same document.

Let’s remove the background from the dog.

Choose the Quick Selection tool

At the top (if you have the option) by select subject, choose Cloud. If you don’t see this option, this will still work, just not quite as well.

Click Select Subject

You will see a selection around the subject (the dog).

Let’s make the fur selection edges look better,

Choose Select and Mask

Grab the Refine Edge Brush (it will be selected by default).

Drag the brush around the edges of the fur. Make sure the brush is positioned 3/4 outside the subject for the best results as you paint (at least this 3/4 seems to work best for me)..

Select and Mask is on the right-hand bar; click Decontaminate colours. The fringes will have less colour as a result.

Select Output: New Layer with Layer Mask.

Press “OK”

STEP 3: ARRANGE AND POSITION THE CUTOUT

ou will see something like this. Do NOT reposition or scale anything yet!

Make sure all layers are visible, by clicking the eyeball.

Drag the Original dog layer to the bottom.

The original dog layer and the extracted dog layer should now be wedged between your screen and them. The extracted layer sits on top so it can overlap, but the original layer will still be visible via the hole in the screen.

Making ensuring the two dog layers are always chosen together is crucial.

Click on the name of the other dog layer in the layers panel while holding down the Ctrl or M key.

The two Dog layers should be chosen as displayed. To display the layers, I added the blue boxes.

Press Ctrl/Cmd+T (Ctrl+T Windows / Cmd+T Mac).

STEP 4: ADD A SHADOW

Choose the top layer

Choose fx in the layers panel

Select Drop Shadow

There will be a shadow.

To reduce the shadow and opacity, increase the size.

To move the shadow in the picture, drag on it.

To use, press “ok.”

The shdow work on the screen because it makes it appear to come off the screen. But we need to remove it outside of the iPad boundaries. Shadows don’t float in the air.

Click on the word effects in the layers panel

Right-click

Choose Create Layer

To aid in our masking, we can use a prior selection as a stencil.

Hover over the thumbnail for the iPad screen mask while the Shadow mask is still the active layer. A square with dots will be seen.

To load the selection, click.

selecting a brush (B key)

Set Black as the foreground colour.

At the top of the screen, set 100% for both flow and opacity.

To get rid of the shadow on the dog’s head, paint over the top of the illustration.

(Try flipping the selection if nothing happens. Select>Inverse)

For the thumbnail, I added some water splashes. For this I just used a brush. See other tutorials on Custom brushes.
