You can open or download an excellent (slightly dated, unrevised since ACR 6.1 but finally translated into English from the original Italian by Francesco Marzoli) guide to all the deeper functions and tricks of efficient workflow using Adobe Bridge, Camera Raw, Lightroom and Photoshop from X-Rite:
This PDF instruction book obviously mentions the use of X-Rite’s ColorChecker Passport for calibrating cameras, that’s why they have sponsored the guide. But it goes far beyond this to explain with clarity all the controls of ACR, and many tips are given on how to use them best.
As an example, we didn’t know that Bridge could be forced to use Camera Raw without taking over Photoshop – meaning it can be run separately, allowing you to do other work in Photoshop while ACR does file conversion and saving from within Bridge alone.
You can load this guide into your iPad or other reading device. Just SAVE the target file, and ADD to your iTunes Bookstore Library, it will then be readable. For other devices simply save the PDF and transfer.
