You will learn how to easily replace the sky in a photo using basic selection tools and a layer mask to separate the sky from the area below it. Photoshop’s Advanced Blending sliders makes it easy to replace the original sky. Once you learn how to do this it takes a minute to replace the sky. Join us to learn more on our Real Estate Photography FaceBook Group.
Click on the below images to make them larger.
Open the original image that has the sky you want to replace. Now duplicate that as a new layer to be on top. Open the new sky image and layer it below the original image.
Use the lasso tool to click around the lower area of the original image.
Click on the layer mask.
Double click on the duplicate layer. This opens Photoshop’s Layer Style dialog box set to normal . What we’re looking for are the two slider bars at the bottom of the dialog box, in the Advanced Blending section. Directly above the slider bars is the Blend If option which, by default, is set to Gray. Click on the word Gray and choose Blue from the list that appears. Adjust The Transition Between The Photos To Remove Fringing
The only problem now is that we’re seeing a lot of harsh edges and fringing around the trees and leaves, which is color that’s left over from the original sky. To fix that, we need to soften the transition between the two photos, and to do that, we need to split the slider in half.
Release the slider for a moment, then press and hold your Alt (Win) / Option (Mac) key on your keyboard. With the key held down, click back on the slider and continue dragging it towards the left. This will split the slider into two halves that we can now drag independently of each other (you can release your Alt / Option key at this point). We can adjust the softness of the transition between the original photo and the replacement sky photo by increasing or decreasing the distance between the two halves of the slider.
Keep an eye on your image in the document window as you drag each half of the slider left or right until all of the fringing around the trees and leaves (and anywhere else you happen to notice fringing) disappears:
Adjust the sky where you want it to be and merge the layers. You now have a new sky.
