Verticals
Set it straight
Straight verticals are the hallmark of a good interior image. Barrel distortion and perspective prevent an image from having straight verticals throughout, but even so, getting as many verticals straight as possible in-camera will prevent you having to crop too far into the image when straightening it in post. Use the grid overlay in Live View to line up walls and objects, and then straighten any skewed uprights you’re left with in Lightroom. In the Develop Module, ensure Enable Profile Corrections is ticked in the Lens Corrections panel and then head to the Transform panel and select Vertical.
