I'm fairly new to Aperture 3 and have encountered a problem I haven't seen before. Last night I imported three sets of files from the same camera. The first set was fine but the next two displayed in portrait rather than landscape. I selected the photos and rotated to landscape, but have no idea why they all imported in portrait. I looked in the import settings and the preference file but didn't see anything obvious. Thanks for your help.
What camera and lens? Raw or JPG or both? Were they all shot in landscape orientation? Did they show properly in the Import pane?
