For whatever reason it is always fun to create composite images that use star fields as a backdrop. Star fields have a unique ability to make a composition look mysterious and even magical. In today’s tutorial we will demonstrate how to create a 4-piece stardust composition using textures and masks. Let’s get started!

Step 1

Let’s begin by making a 1000×900 document. Place the first image, Girl 1 into your document. We’ll be resizing this photo slightly, so press CMD+T and type in 90% for the width and height. To keep track of our layers (because there will be 4 photos), rename the layer to “Girl 1″.

---

Step 2

Now take Girl 2 and place it into your document. We’re going to be using this image twice so press CMD+J to duplicate it. Press CMD+T on the newest image and resize that to 60%. Rename the regular sized image “Girl2″ and the newly resized image (the one we just resized to 60%) to “Girl 2 Resized”.

---

Step 3

For our last picture place Girl 3 into your document. Once again press CMD+T and resize it to 50%. Rename this layer to “Girl 3″.

---

Step 4

Make sure your pictures are all correctly named, then we’ll begin to assemble them. I like to move pictures around and have a variety of smaller and bigger pictures to balance the blend. Assemble your blend according to the picture below, or if you can think of something better go for it! But if it ends up looking better than mine, let’s just keep that on the downlow

Step 5

Before we begin fill the background of your document with black.

---

Step 6

Because we’re using a black background, setting the layers to “Lighten” will help us blend better because they show through. Set all of the image layers to “Lighten”.

---

Step 7

Select “Girl 3″ and press CMD+T. Then change the angle of the image to -6.4. Once you’re done, move “Girl 2″ a few pixels to the left so it’s closer to all the other images.

---

Step 8

We’ll now begin the base of this graphic by blending. You can blend in a variety of ways, but the best way to do it is to use masks. This way, if you make a mistake or feel the need to change something in the picture, you can easily do so. Since we used lighten, it’s a bit easier to blend because we can see where everything comes together, but we need to refine some things. So go ahead and make a mask first on "Girl 2" by clicking the Vector Mask button on the bottom of the layer palette.

---

Step 9

Select the mask, and then you should see your color palette change to black and white. Black erases your photo, and white adds it back on. Go to your brush tool and select a default 200px diameter round brush, 0% hardness. We want a nice soft brush so blend everything in nicely. Begin to erase away the edges of “Girl 2″ so it blends smoothly with the rest (use black). I’ve marked the places in red you should erase. Erase the areas marked in red.

---

Step 10

Now repeat this step for the rest of the images until they’ve been blended together well. On "Girl 1" create a mask once again, and then erase the areas shown.

---

Step 11

On "Girl 2 Resized" create a mask once again, and then erase the areas shown.

---

Step 12

On "Girl 3" create a mask once again, and then erase the areas shown.

---

Step 13

Now we’ll make some revisions. Go back to the “Girl 1″ mask and delete the bottom part of the picture as marked. It’s good to go back and make sure everything blends well, sometimes you might miss things!
