Need more photo management grunt than iPhoto can deliver? Adobe's
Photoshop Lightroom is for you, enabling photographers to import,
select, develop and present large volumes of digital photographs, with
the express aim of letting photographers spend less time sorting and
organizing images so they can spend more time what they love doing
most -- taking photos.
