Hi. This is Marty from Blue Lightning TV. I'm going to show you how to swap faces. The
technique can also be tailored to swap just specific features which will create a fun caricature.
Open the photos of the two people whose faces you want to swap.
I downlaoded these and the others from Shutterstock.com.
Both faces should be focused, be facing in the same direction and be lit from the same angle. Decide which
person you'd like to transplant the face onto and make a copy of it. To do this, press Ctrl
+ J on Windows or Cmd + J on a Mac. Open the other photo and open your Lasso Tool.
Drawaround the eyes, nose and mouth, leaving room around the features. If you want to swap just
one feature like, say the nose, just draw around the nose to select it. Press Ctrl or
Cmd +J to cut the image inside the selection and copy it to its own layer. To place the
face onto the other person, press "v" to open your Move Tool and drag it onto the tab of
your other subject. Without releasing your mouse or pen, drag it down onto the image
and release. Drag it over the other face and reduce its opacity, so we can see through
it. To resize it, open your Transform Tool by pressing Ctrl or Cmd + T.
Go to a corner and when you see a diagonal, double-arrow,
press and hold Alt or Option + Shift as you drag it in or out.
To reposition it, drag inside the Transform so the eyes line up on
the face. To rotate it, go to a corner and when you see a curved, double-arrow, rotate
it until it matches the angle of the face under it. Once you've sized and angled it,
increase its opacity back to 100%. Feel free to finesse its size, angle and position until
you're happy with it. Then, press Enter or Return.
Ctrl-click or Cmd-click on the thumbnail of the face to make a selection of its shape.
Go to Select, Modify and Contract.
I'll contract it 10 pixels, however,
you may want to adjust this amount depending on the size and resolution
of your photo. Type in an amount that contracts the selection approximately this much.
Make Layer 1 active and press the Delete key on your keyboard to delete the area of the image
inside the selection. If we hide the top and bottom layers, we can see the area it deleted.
Now that we deleted that area, we can deselect it. Make the bottom and top layers visible
again and Shift-click on the the face to highlight both layers. Go to Edit and "Auto Blend Layers".
Tick "Stack Images" and make sure "Seamless Tones and Colors" is checked. Then, click OK.
Automatically, it blended together the colors, brightness and contrast of both images.
We chose "Stack Images" because this option works best with aligned layers, which is what
we have. It blends the best details in each corresponding area. The Auto Blend Layers
command applied layer masks to each layer to mask out over‑ or underexposed areas.
To make a seamless transition between the two layers, make a composite snapshot of your
image by pressing Ctrl +Shift +Alt + E on Windows or Cmd + Shift + Option + E on a Mac.
Hide Layers 2 and 1 and click the Layer Mask icon to make a layer mask next to the active
layer. Open your Brush Tool and Brush Picker. We'll take care of the size in a moment. Make
the Hardness: 0% and the Opacity and Flow: 100%. Then, press Enter or Return.
To make your brush larger or smaller, press the right or left bracket keys on your keyboard.
Now, brush over the areas that you want to have a smoother transition.
