How to Light photos with Clipping Masks in Photoshop

This Photoshop tutorial will help open new way to work in Photoshop. I did a previous tutorial on Lighting in Camera RAW and Lightroom with the new masks. I had a number of people ask, how to do this same thing in Photoshop. This tutorial shows how to make Lightroom style masks in Photoshop, but a whole lot more too. Photoshop’s layers, masks and selections are more powerful and flexible than Lightroom or Camera RAW. They are faster and simpler in LR and ACR though.

How to Use Clipping Groups in Photoshop

The first part is a quick primer on how Clipping Groups work, then we will do the lighting effects,

We are going to select the shirt on the photo.

Choose the Object Selection tool.

Make sure the mode is set to Lasso at the top.

Object Selection Tool chosen in the Photoshop toolbar with Mode set to Lasso

Make a rough selection around the shirt. With this AI tool, you aren’t really making the selection, you are telling Photoshop what you want selected.

Photoshop will make the selection for you. (You can use the lasso or other selection tools to improve the selection if needed).

Press Ctrl/Cmd+J to copy the selected shirt to a new layer. (Normally I’d use a mask, but I’m just demonstrating clipping groups here and want to keep it simple, we will use a mask in a moment).

Here I added a graphic to put on the shirt. (I dragged it from the Library, you can see on the video).

If I hide the background, you can see just the shirt and the graphic.

I want the graphic to fit INSIDE the shirt, and not show outside.

Move you curser between the 2 layers in the Layers panel.

Hold down Alt/Option and you will see a square arrow.

Click to add a clipping group.

Notice the top layer displays as indented

Notice the graphic is now contained within the shape of the shirt.

A clipping group constrains the visibility of the top layer to the pixels (or shape) of the layer underneath.

If I turn the background back on.

You can drag the top layer around and reposition, or resize it and it will stay constrained to the shape. (Alt/Option Click to ungroup it again).

I changed the color of the graphic and changed the blend more to make it look better. Learn About Blending Modes here. | Add a displacement Map to wrap to the wrinkles

Ok, onto the tutorial

Making Clipping Masks in Photoshop

In this image, we are going to make a clipping mask in the shape of our singer in the photo, so we can add some nice lighting to her.

Start by duplicating the layer. Cmd/Ctrl+J

Layers panel with the singer photo duplicated as Layer 1

Choose the Object selection tool

Click the options arrow in Select Subject

Select Subject options arrow highlighted in the options bar

Choose Cloud as the option, if you are connected to the internet. (This makes a better quality selection than Device)

Select Subject menu with Cloud detailed results chosen

Click select subject and you will get a selection around the woman

Click the add mask button in the layers panel. (We are doing this instead of cutting out our subject. A mask allows modifications to the edges and is non destructive).

In this screen grab I hid the background, so you can see the transparency. (You don’t need to hide the background.)

Click on the foreground picker at the bottom of the tool bar.

Choose a golden color

Color Picker choosing a golden yellow foreground color

Grab the gradient tool

Choose foreground to transparent option (in Basics)

Choose linear Gradient

Gradient tool with a yellow to transparent gradient chosen in the options bar

Apply the gradient to the image by dragging.

Notice the gradient covers the background and the person. We just want it on the person

Yellow gradient dragged across the singer and the smoky background

Just like we did with the shirt example, lets make a clipping group.

Hold your pointer on the line between the masked layer and the gradient layer in the layers panel.

Hold Alt/Option, wait for the square arrow, click

Yellow gradient layer clipped to the singer layer in the Layers panel

You can move the gradient around and notice it stays constrained to our person. This is our clipping Mask.

Change the blending mode of the gradient to Soft Light and reposition it to add a more subtle effect on the edge.

You can also adjust the gradient layer opacity if you like.

Blend mode menu with Soft Light chosen for the gold gradient

Here we repeat on the left side, but with a blue gradient

Hold the Alt/Option key and move it between the 2 gradient lAyers and click.

Notice we can stack layers above each other and they can all share the same mask as long as they are clipped. See the indentation and arrows to indicate they are in a clipping group.

Two gradient layers clipped to the singer layer, clip icons circled

This time I used an Overlay blending mode. Just use the Blending mode that looks the best for each color, there is no rule, but I find I use Overlay, Screen and Soft light a lot when Lighting.

Using Adjustment Layers with Clipping Groups

Ok, let’s do some custom lighting now.

Choose the New Adjustment Layer in the Layers panel

New adjustment layer button in the Photoshop Layers panel

Grab Curves

Curves chosen from the adjustment layer menu

Let’s increase the brightness by dragging up in the Curve in the Properties panel.

Curves raised in RGB to brighten the singer

We are going to change the color too. Choose Red in the top of the Curves

Red channel chosen in the Curves properties panel

Drag up to add Red

Red curve raised giving the singer and stage a warm red tint

I want Orange, Red+Yellow= Orange

We now need yellow. You will find Yellow by dragging down the the Blue channel. How to use Curves for Color in Photoshop (Curves are super powerful and can do a LOT. I made a course on Photoshop Curves here)

We have our colored light, but it’s everywhere. Lets contain it.

Blue curve lowered for an orange cast over the whole photo

As before, move your cursor between the 2 layers and hold Alt/Option and click to make a clipping mask.

Now the curves can only appear within our person.

Curves adjustment clipped so the orange light only affects the singer

But we want to hide the lights and only paint them where we want them.

Click on the mask on the Curves layer (White rectangle)

Press Ctrl/Cmd+I to invert our mask.

It now shows as Black and the effect is hidden.

Grab a Brush (B key)

Set the foreground color to White

Drag on the right edge of our person. Notice it now lights up with the orange light.

Orange rim light painted along the right edge of the singer

The beautiful thing about the Clipping Mask, it’s impossible to paint outside the shape of our person.

This makes it easy to add a Rim light, or paint on the edges.

Here I added a Blue light on the other side, following the same steps.

Here you can see the before and after of this effect

    Fantastic, Colin! I use clipping masks all the time. Never considered using a layer mask as the clipping mask. Can’t wait to put this to use!

  2. Terence Starkey

    Fantastic work. Many thanks for your informative tutorials. I am amazed how far Photoshop has developed since I started using it in the 1990s

  3. Really great Colin. Plus it cleared-up some other general questions I had about clipping masks. Big Thank you.

  4. Svein Ivar Ask

    I have followed you and your Tutorials for some time ( and recommended them to my friends). This one I have seen several times, and made great use of. If we ever met – which is not likely since I live in Southern Norway – I would shake your hand for a while , just to say Thanks . 🙂
