Lightroom CC 2015.4 and Lightroom 6.4 are now available on Adobe.com. The goal of this release is to provide additional camera raw support, lens profile support and address bugs that were introduced in previous releases of Lightroom. This release also includes a new Boundary Warp feature for Creative Cloud members.
Introducing Boundary Warp (New Feature)
Stitched panoramas often have non-rectangular boundaries. There are several ways to handle irregular boundaries. The most common approach is to apply a rectangular crop. This is straightforward, but important image details near the boundary may be lost due to cropping. Another approach is to use Content Aware Fill (in Photoshop) to fill in the transparent areas outside the boundary. This can be effective, but may require multiple attempts to obtain a satisfying (smooth, artifact-free) result. It can also be expensive and requires rendering out the panorama to an output-referred(non-raw) format. Boundary Warp is a feature that provides another approach to handling the irregular boundary of panoramas. The feature analyzes the boundary and warps the image so that its edges fit a rectangular frame. Here’s a visual example of the feature:
