Iphoto doesn't have enough options to manage my 25k+ collection. I need Aperture. So I think my work flow will be keep all my originals and import images into iphoto. That way : Time Machine will work, my camera videos will have a home for future editing, and the PS3 / Medialink HDTV viewing will work. Then, I'll import everything into Aperture 2 as referenced images and use Aperture to reorganize the images and make minor image tune-ups (without iphoto making unnecessary backups), and then use PS for any heavy image corrections.
My question now is after an image is edited in PS coming from Aperture, when it is saved, is another master created in Aperture ? also will I still have to periodically save the vault to capture the Aperture edited images ?
