During Adobe MAX 2016, the company gave a behind the scenes look at a new technology that they’re developing called SkyReplace. The new software makes it very easy to replace the sky and even adjust the overall look of a photo with little to no Photoshop knowledge.

Adobe says SkyReplace uses deep machine learning to automatically figure out where the boundary lines lie between the sky and the rest of the elements in the photo such as trees, mountains and buildings. It can then not only swap out the old sky and insert a completely new one, but it can also adjust the rest of the photo to take on the same look and feel as the replaced sky by adjusting color, light and contrast thus creating a more realistic look.
