Adobe photography evangelist George Jardine is switching gears a bit in his latest Lightroom Podcast.  He’s posted a video "mini-tutorial showing you how the Quick Develop Panel can help you make a snap correction in the middle of an edit using Compare View, without breaking your concentration or workflow." George writes,

This mini-tutorial podcast is the first in a new series that will cover bite-sized tips and techniques designed to help you get the most out of Lightroom. The focus of this series will mostly concentrate on basic color correction techniques using the Develop module, but will also touch on many other parts of the application. This first tutorial shows the basics of using the Compare View to edit a small group of pictures to “find the best shot,” and how to use the Quick Develop Panel during the edit.

The podcast is available via George’s iDisk (look for “20070418 Tutorial Podcast – Compare View + QD”).  It’s also available via iTunes (search for "Lightroom"), and via the Lightroom Podcasts RSS feed.
