Scroll down to Borders & Textures and check the box to add one. Choose the basic black border for this image so as not to get in the way of the photograph. There are some crepuscular rays already, but emphasize the dreamy light by adding more. Check the box for Light Effects, then scroll through until you find the High Sun Flare. Lower its opacity so that it doesn’t totally wash out the trees at the top of the image. When you’re finished, click Apply to process your image and head back to Lightroom.
Adding Borders and Textures
There are so many options here that it makes sense to search by category. After adding one, use the fine controls to change its size and orientation.
