What’s wrong with this photo of a boat on a shingle beach? I used a prime lens with a wide maximum aperture to get a shallow depth of field effect for this simple composition and that part has worked well. But the boat is just a little too dark and the sky is a little too bright. This is a common issue in outdoor photography.
Sky mask (Lightroom)
This is one of the AI masking tools in Adobe Lightroom. It can automatically detect and select any sky areas in a photo so that you can enhance them separately to the rest of the image. Other programs can do similar things, such as ON1 Photo RAW and Skylum Luminar with their AI sky replacement tools.
