Yesterday Adobe released Lightroom CC 2015.6. The big news for Leica users is support for the new Leica M-D, the screen-less Leica M (Type 240) based camera.

This release for Creative Cloud members include the new Guided Upright feature.
It’s designed to easily straighten images, fix horizons, and reduce or eliminate the keystone effect in buildings.
I’ll be testing it with a few Lincoln Cathedral shots to see if it affects corner resolution adversely.
