This is my movie poster for  "Beneath the Surface". I used the image of the girl twice in this project.  I photoshopped her underneath a water effect that I created myself. The hand coming out of the water was cut from the same photo and placed above the water to create a reaching effect.  I then made a ripple around the wrist to create the water movement of the hand reaching out.
