Adobe has released an update to its Photoshop Lightroom 3 beta software through Adobe Labs.

The digital photography workflow software has been updated based on user feedback from the first beta.

New features in this Lightroom 3 beta 2  includes tethered shooting support for select Nikon and Canon cameras, the ability to import and manage video files from DSLR cameras for a streamlined workflow and additional behind-the-scenes architecture enhancements for faster importing and loading of images.

The addition of luminance noise reduction to the colour noise reduction options already available in the beta helps photographers achieve overall exceptional image quality from high ISO images insists Adobe. The import experience and watermarking functionality have also been modified based on user feedback.

Adobe Photoshop Lightroom 3 beta 2 is available as a free download to Mac and PC users in 12 languages.

Adobe notes the first Lightroom 3 beta has been downloaded more than 350,000 times.
