You have completed the first step of creating a double exposure image. Make sure the shape you want to keep is black and the part you don't want is white (usually the background). You will understand what it means when working with Blending modes.

Here's how to use the Double Exposure feature:

Step 1. After finishing editing to a black shadow on a white background, go to Tools > Double Exposure.

Step 2. Click the Open Image option to add a second image.

Step 3. Position the second image as you want and choose the Lighten blending mode from the Style options. The image will only display in the dark area.

Step 6. Refine your image with some final tweaks, adding effects and filters if required before exporting the final edited result.

You already have your double exposure and can experiment with it a lot more however you like. You can add objects to another image or create something similar to a movie poster. TipsMake also has a tutorial for creating a double exposure effect in Photoshop .

Two important steps while using the Double Exposure function is to use the Blending modes properly and use the Slack Brush to mask the less important areas. Slack Brush is similar to using layers and masks in Photoshop.
