This lesson shows how I tackled a challenge image that was submitted by a Masters Academy member. Sean wanted to replace the background that appeared behind a glass panel. In the end, I completely reconstructed the glass panel from scratch using curves adjustment layers. I think you'll enjoy this lesson even if you never have to perform a similar task since you'll learn a good amount about working with adjustments and masks. If you want to see how I overlaid the original image on various backgrounds in Lightroom, then check out the Lightroom Image Overlays lesson.
