I currently use Aperture 3.1 for tweaks and library management and I'm happy with it for that purpose, but I am considering buying Photoshop CS5 for more extreme editing. I was wondering if there was any advantage in migrating to Lightroom at the same time?
Does using PS+LR as a team enable features that PS+other can't support?
For example,
Are adjustments made in LR preserved as non-destructive edits (adjustment layers?) when a photo is exported to PS?
Does working with PS+LR require fewer intermediate files than PS+other?
Does Aperture support .PSD files, or do I have to convert to TIFF before I can archive my files in Aperture? Does that mean losing editing flexibility?
NB: I'm not asking if LR is better than Aperture, only whether it integrates better with PS.
