Choose the picture you want to upload. Either take a picture of yourself or choose one from your computer.
Connect your digital camera or phone to your computer using a USB cable and transfer the picture from your phone or camera to the computer.
Download a picture of the celebrity of your choice from the Internet. Pick a picture of yourself in the same lighting, attire, scenery and of low resolution.
Open the two pictures on separate layers on your Photoshop software. Place your picture on the upper layer.
Select the image of the celebrity using the lasso tool or quick selection tool. This creates a boundary between the images and eliminates the rest of the picture.
Copy and paste the image of the celebrity onto the layer that contains your picture. Place him next to you in a convincing manner.
Add a layer mask that hides all to the upper layer. Use a brush tool to brush the areas you want the background to show.
Vary the opacity levels to reveal the background. This enables you to blend the two images.
