Any photographer who does team and individual photos will frequently
run into a situation when some players in a team photo have their eyes
closed. While taking multiple photos usually prevents the need to do
advanced editing in Photoshop, sometimes it doesn’t work out that way.
Here is a simple way to use Layer Masks in Photoshop to solve this
dilemma. The beauty of this technique is that it works great for any
group photo including family and wedding photography.
This is a quick and easy tip that will work wonders for your
photography. We are going to combine two images using a layer mask and
the Brush tool. While we are using Photoshop CS6 in this tutorial most of the features are available in earlier versions of Photoshop.
A Few Pointers
I’ve mentioned this in previous articles but it’s worth repeating
because it’s a huge time saver. One of the best time saving tools in
Photoshop is the use of keyboard shortcuts. You can find a full list of
the
keyboard shortcuts available
in Photoshop or use the keyboard shortcut “Alt+Shift+Ctrl+k” in
Photoshop. It is important to note that all of the keyboard shortcuts I
reference here are for PC. Rather than give you 2 options for every
shortcut, just follow this rule: if you are using a Mac, just swap
“Control” for “Command” and “Alt” for “Option”. As always, I recommend
saving your work often. Simply pressing “Control+S” after making
changes will save you a lot of headache if Photoshop crashes. If you do
not have a powerful system this can happen from time to time.
Combining the Photos
We need to place the “eyes closed” image on top of the “eyes open”
image as a new layer. This can be done by simply dragging the layer
from one image to the other. However, if you use the Photoshop default
that opens your documents as tabs, this isn’t as easy. A quick trick on
how to move a layer to another Photoshop document is to use the
Duplicate Layer command. To do this, click on the Layer drop down menu
and select Duplicate Layer. This will bring up the Duplicate Layer
dialog box as seen in Figure 3. In this case we want to change the
destination to our other image. Simply select that image in the drop
down menu and click OK.

Duplicating The Layer To A New Document
Aligning the Layers
Now that we have our “eyes closed” image on top of the “eyes open”
version, we need to align the layers so her eyes line up properly. In
some cases this can be done using the Align tool, but if the images were
not taken at the identical focal length this may not work. In this
case it is easier to just do it manually by adjusting the opacity of the
top layer. With the top layer selected press “V” to select your direct
selection tool. Now press 5 to adjust the opacity to 50%. You can do
this manually by adjusting the opacity in the Layers Panel as well. The
result is going to look a little weird at first but use your arrow keys
on your keyboard to nudge the top layer around until it lines up nicely
over the person to whom you are making the changes. As you can see in
the photo below, the girl is lined up properly even though the rest of
the team isn’t Remember, we are only making changes to her so the rest
of the team doesn’t matter here. Now that they are aligned, press “0”
to set the opacity back to 100%.

Aligning The Layers
Using Layer Masks
Layer Masks can be a little intimidating at first but once you get
the hang of it you will wonder how you ever lived without it. When we
use a Layer Mask we are not changing the actual image, which is why it’s
called “non-destructive editing”. In this scenario, if you used the
Eraser tool, we would be making permanent changes to the layer–we can
avoid that by masking. The most important thing to remember with
masking is that white reveals and black conceals. Before you add the
layer mask you need to make sure that the layer you’re adding it to is
selected in the Layers Panel. The selected layer will be highlighted in
blue. Here I can see that my top layer is selected so I’m ready to add
the mask to it. In the Layers Panel, click the Create New Layer Mask
icon as shown in the image below.

Create New Layer Mask
By default, layer masks are added as white, meaning whatever they are
masking is 100% visible, so you won’t see a change in your image when
you add the mask; however, you will see a white layer mask thumbnail
next to the layer’s preview thumbnail as seen in here.

Layer Mask Thumbnail
It is important to understand that layer masks use only white, black,
and shades of gray. These colors are simply used to control the
transparency of the layer under the mask. Now, we know that white means
100% visible so what do you think black is? That’s right, black “masks”
the layer making it 100% transparent. Gray is going to be somewhere in
between. In our case, we want to show the photo of the girl with her
eyes open without affecting the rest of the team. We are going to paint
on the mask in black to reveal the layer below. To do this, select the
Brush tool from the Tools Panel or with the keyboard shortcut “B”.

Select The Brush Tool
We will be painting in black so we need to make sure black is
selected as our foreground color which is the Photoshop default. You
can always set your colors back to this with the keyboard shortcut “D”.

Setting Black As Foreground Color
You need to make sure you are painting on the mask and not the layer
itself, so make sure to click on the white layer mask thumbnail in the
Layers Panel. When it is selected a white box will appear around the
thumbnail. You won’t get too far if you have the layer selected by
mistake because you will immediately see black being painted directly on
your image, which is not what you want to see.

Targeting The Layer Mask
You should be able to see a circle for your cursor that shows you the
brush size. As a real quick side note, if you don’t see the circle
indicating your brush size make sure that your Caps-Lock is set to OFF.
If Caps-Lock is on it disables the brush size indicator, it took me
forever to figure this out so hopefully this saves someone a little
hassle. You can adjust the brush size manually in the upper left side
of the toolbar or by using the open or close bracket “[ ]” keyboard
shortcuts. You want to use one of the fuzzy brushes because you need
to blend it in nicely or it will look unnatural.

Brush Size
Now we just paint in black on the mask over the girl’s face and, like
magic, it reveals the layer below which has her eyes open. If you mess
up and paint too much black just use the keyboard shortcut “X” to swap
the foreground and background colors and paint the area back in with
white. As you can see in our finished photo below, the girl’s eyes are
now open and the rest of the team photo hasn’t been modified at all.

Finished Photo
Conclusion
You can see how layer masks can save you a ton of time and headache
when you need to blend group photos together. This is just the tip of
the iceberg when it comes to the power of layer masks in Photoshop CS6
and countless hours can be spent on the different ways to use them.
However, by starting out with a simple project like this one you can
easily learn the basics of masking without getting discouraged by the
complexity of the tool.
