As a landscape photographer, I know what it is like to return to the same location day after day hoping for a dramatic sky at sunrise and sunset. But the reality is you cannot stay at the same location forever waiting for that perfect sky. This means that occasionally you need to replace the sky in Photoshop, which is same process as changing a background in a portrait photo.
I created a video tutorial to demonstrate how to change a sky in Photoshop based on a panorama image I shot at the lavendar field at Senanque Abbey in Provence, France.
