Hi Does anyone know the difference? I already have iPhoto 08 on my Mac? Do I still need Photoshop Elements AND Light Room? There seems to be a lot of overlap - all have a database to store your photos - Adobe Photoshop comes with Bridge. Light Room is a database, and so is iPhoto. I have over 20,000 pictures and am in the process of scanning all my negatives (8000-12000 pictures) using a Nikon Coolscan. I want to correct some of the scans, remove scratches, do some cropping etc. Will iPhoto be enough? If I have all three, does that mean I have three copies of all my photos? Can Light Room do everything Photoshop Elements can do? Reason I am asking now is that, I whilst I was running Tiger, I have iPhoto for managing my library and Photoshop Elements 2 for quick fixes. I upgraded to Leopard, but Photoshop Elements 2 does not work. This leaves me a choice - upgrate to 6 or go for Light Room instead?
