You may have noticed that when M. James Northen was describing his process for shooting the image we featured about a month ago he mentioned that he used a Expodisc. If you are not familiar with with the Expodisc, Ken Rockwell has a great article on the subject. Basically it's a filter like device that helps you get accurate white balance at capture time rather than make adjustments in Lightroom or Photoshop. There are always some that would rather do more at capture time than in Photoshop. On the other hand some folks are more comfortable in Photoshop and find it easier to image-edit than to buy equipment.
I bring this up be cause Karl was wondering how widely the Expodisc is used and if most RE photographers address white balance at capture time or in Lightroom and Photoshop.
I personally love the way shooting RAW allows you to make white balance adjustments during photo-editing. The less technical camera things I have to pay attention to while shooting the more I can focus on composing and thinking about the aesthetic aspects of the shots. But I know there are others out there that are on the "other side of this fence". A very compelling feature of both Lightroom 1.0 and Photoshop CS3 (actually I think this is a feature of Camera Raw 4.0 which they both use) is that even if you are shooting to JPG, Lightroom and PS CS3 allow you to adjust white balance in the same way as if you shot in RAW.
