LIGHTroom: adjust brightness for entire Blurb book

Hi Adobe team,

Just as the Print module has a Print Adjustment section in the Print Job properties (to adjust brightness/contrast for all prints), it would be very convenient to have this for Blurb books too!

Many people complain that their prints are (a bit) too dark and then they are faced with complex color calibration information, and then the Blurb ICC profile doesn't work with LR, etc, etc.

A simple "turn up brightness" button just before uploading your book would be simple and effective for most LR users. Then there's no need to manually adjust all photos in your book (and after uploading the book, re-adjust for screen).

Thanks,
Kris
