In this landscape photography video I take you from the very basics of layer masking in Photoshop, right through to demystify luminosity masks for exposure blending. Luminosity masking is sometimes seen as being a complicated technique, but in reality it is very easy to grasp and extremely powerful in blending complex multiple exposures for your photography. I use an example of an image captured in a previous video to demonstrate how three exposures are brought together to create a balanced final image.
