9) Click ok to render the image. Now from the menu above, choose Image -> Adjustement -> Hue/Saturation.
Choose the color you want. Suggested is green or yellow, this reflects scary aliens.
10) Now with your brush tool, brush the outer areas with black and leave only the man and the woman.
11) To realize the aliens dating, I attached an image of the space.
12) Place this image as a background.
TIP: Import the space image as a layer and place it on bottom. Then you can remove the black areas in the initial picture either with the erasing tool, or by selecting that area with the selection tool and then hitting delete on your keyboard.
13) Now using the type tool, type “Alien’s Real Love” , or anything else you like.
That’s it. Hope you like this tutorial.
