With 1.5's new feature to not contain all my photos
within a single library file, should I leave my
library as it is (after importing tonnes of photos)
or should I move them all out into folders again?
Just curious, what are you going to do with YOUR
library?
I'm still going to keep using the images stored in the library, because I like having all my master image data along with versions and edits in a single place.
What I am really curious about is just what will happen when you edit an image externally if you are using a master outside the library. Currently Aperture makes a new master which is a TIFF or PSD file it sends to the external application. Will that master be placed alongside the master held outside the library, or will it always go in the library? Neither answer is really that great, and so I prefer to keep things inside the library outself for Aperture to manage.
If the mechanism for offline storge is that you migrate master files onto a DVD, then I would probably make use of the external storage in that way.
An interesting thought is that you could have virtual masters. Currently as my camera is not supported by Aperture I import 16-bit TIFF files. I could do desired adjustment and other work based on these TIFF files, then migrate them outside the library and simply delete them - I can always recreate the exact same TIFF files later from my RAW versions in case there was a future need for the ful-size version, so it would save some space (especally for images I am iffy about but do not dislike enough to remove).
