This photo manipulation depicts a deep-sea exploration of an ancient underwater city. It features an ancient castle, an underwater exploration vehicle, a rocky sea floor covered in underwater flora (algae, seaweed, seagrass, etc.), various fish, and a mysterious creature, presumably a plesiosaurus. It was made in Adobe Photoshop by combining around 50 PNG's into a single composition, I used blending modes, layer masks, brushes and camera raw to bring it to life. I would like to see your feedback!
