In this video tutorial, I will show you how to create a perfect sky selection even in difficult cases, using Channels, Levels and an Overlay Brush.
In this video, I am showing you a trick that helps you create highly precise masks in Lightroom. The idea is to take a 2-stage approach by first creating a mask that extends beyond the edges of the area you're trying to select. At the second stage, we're going to use the Eraser brush with the Auto Mask feature to get rid of the excess mask areas.
There are a thousand ways to create a layer mask in Photoshop. Many of them will yield a gray-scale mask with many shades of gray, and it can be a bit difficult to get the contrast of such a mask just right so that you have solid black where you want to hide the layer and solid white where you want to reveal it. In this excerpt from my Mask It Like a Pro! video course, I will show a neat little trick that allows you to get the perfect mask in such cases. I am using the Brush tool with Black and White as the color. The trick here is to set the mode of the brush to Overlay.
