[dba-Tech] Adobe Lightroom 3

Hi all
 
I'm hoping that someone else out there uses Adobe Lightroom 3 - Because I've
got a lens that distorts straight lines a lot, and I can't work out how to
apply the correction manually, rather than to each individual picture in
turn (especially to the current album of over 600 photos...).
 
Does anyone have any ideas??
