Adobe Photoshop Lightroom 2.6.1 should be the exact same as the Lightroom 2.6 was released recently , which added support for several cameras from Canon, Nikon and others, and to correct some problems on PowerPC-based Mac OS machines. But the latest update is only for Leica M9 users, all others should not upgrade and just continue to use 2.6.
The problem arose when processed images from the Leica M9, and this occurred in Lightroom version 2.6 when Adobe did changes to improve image quality earned based on customer feedback.
Lightroom 2.6.1 is available for both Windows and Mac OS .
And if you still have not updated your older Lightroom 2.6 you can download it for Windows and Mac OS .
