Lens Correction: One Last Rabbit in the Hat
The two public betas offered no hint at the rabbit hiding in the Lightroom 3 final release hat. When the new Lens Correction feature popped up in the final version, it marked a major surpriseand a huge step forward.
As photographers happily babble away about conquering chromatic aberration, here's the gist: Lightroom 3 can automatically correct the inevitable distortions and color shifts of a lens. In effect, this feature liberates photographers from spending what had been a lot of time adjusting and tweaking in Lightroom's Develop module.
To see what all the hubbub's about, jump to the five-minute point in this Adobe video.
The Lens Correction panel has a manual section for correcting geometric distortion, something you often see when shooting up-close with a wide-angle lens. Select a photo to correct (see Figure 4), and a light grid appears, making it easy to use a series of sliders to square-up any curving lines (see Figure 5).

The number of lens profiles included in the panel's automatic section is still relatively smallmostly Canon, Nikon, and a few Sigma lenses. But the list of supported lenses will grow in the coming months. In the meantime, thanks to a downloadable "lens profiler," you can start creating profiles for every one of your lenses, no matter how obscure the model.
