Adobe also released Lightroom 5.2, the first major update to the newer version of the image editing and cataloging software. There was no Lightroom 5.1 because of timing complications involving the release of Lightroom and Photoshop, which share the same engine for processing raw-format photos.

Lightroom 5.2 adds a new editing tool, a slider called “smoothness” that’s designed to reduce color-mottling artifacts that are most obvious in digital photos taken at high sensitivity, high-noise settings. These mottled colors often show up as large blotches of reddish or greenish tint to the photo colors.

Adobe also brought improvements to the spot-healing tool, which is used to do things like remove skin wrinkles or dust spots, for example by letting photographers feature the edge of the area being edited. And the auto exposure algorithm has been improved for those who want to let Lightroom take a first pass at photo editing settings, Adobe said.

Also new in Lightroom 5.2 is support for the Canon 70D, an SLR likely to be popular with photo enthusiasts. Other new cameras supported:

• Canon PowerShot G16

• Casio Exilim EX-ZR800

• Fujifilm FinePix HS22EXR

• Fujifilm FinePix HS35EXR

• Fujifilm FinePix S205EXR

• Fujifilm X-A1

• Fujifilm X-M1

• Leica C (Typ 112)

• Panasonic Lumix DMC-GX7

• Panasonic Lumix DMC-FZ70

• Panasonic Lumix DMC-FZ72

• Pentax Q7

• Pentax K-50

• Pentax K-500

• Sony DSC-RX100 II

• Sony A3000 (ILCE-3000)

• Sony NEX-5T

Lightroom also includes preliminary support for two very new cameras, the Canon PowerShot S120 and Olympus OM-D E-M1. Preliminary support for Phase One’s medium-format IQ260 that was in the beta version was taken off the list, however.

For those who shoot tethered — in which a USB cable pipes images directly into Lightroom from the camera as they’re shot — Lightroom 5.2 now supports the Canon EOS 6D, the Canon Rebel Rebel T5i / 700D, the Canon EOS Rebel SL1 / EOS 100D, and the Nikon D7100.

For lens corrections, Lightroom 5.2 can fix images from the GoPro Hero 3 and a variety of Hasselblad, Sony, and Sigma lenses.
