A dramatic sky can make a photograph look great. Lightroom’s Graduated Filter tool offers a quick way to enhance a sky without affecting the rest of the photo.
1. Select the Graduated Filter tool in the tool strip in the Develop module, or press M on your keyboard. In the dropdown Graduated Filter panel, double click Effect to set all the controls to their defaults.
2. Drag the Exposure slider in the panel to the left. This step is optional, but it’s a good way to see where a graduated filter is going to affect your photo.
