Krita Mask-Based Photography Manipulation Template
Source (required if based on other people's work):
Inspired by the GIMP Luminosity Mask tutorial made by Pat David, I have made by a template using a photograph made by the (U.S.) National Park Service at Western Arctic National Parklands. It is 100% nondestructive approach, so you can go ahead and use your image and go straight away to dynamically edit.
