Adobe Systems published a release candidate for Lightroom 3.4 that can process raw images from Canon's latest entry-level SLRs and several other cameras.
The software, along with the accompanying Camera Raw 6.4 plug-in for Photoshop CS5, brings support for, two models likely to be very popular among photography enthusiasts.
Higher-end cameras can record images in proprietary raw formats that capture more information than JPEG but that require processing with software such as Lightroom, Phase One's Capture One, Apple's Aperture, or several other packages. Software makers must keep up with the constant parade of new cameras that offer raw formats. Adobe is often first out of the gate with support for new cameras, but in this case, Apple beat out its Silicon Valley neighbor by a month within February.
Lightroom 3.4 also supports a number of higher-end compact cameras, the Olympus' E-PL1s, E-PL2, and XZ-1, and Samsung's NX11. Much higher up the pecking order is Hasselblad's H4D-40, a new medium-format model aimed to take some of the wind out of the sails of top-end professional SLRs from Canon and Nikon.
Lightroom can correct some optical problems with lenses, and the new release candidate improves or adds support for a number of Canon, Nikon, Tamron, Leica, and Sigma lenses. For the full list, and for a handful of bugs fixed, check the blog post by Lightroom product manager Tom Hogarty.
