Ever since the release of Aperture, Apple only half-heartedly supported metadata in exported photo’s. I don’t know why but Apple decided not to export extremely useful metadata information like lens model and many others as well. Unfortunately, this is still the case with Aperture 3 :( Lens type is still not included in any exported JPEGs or when directly uploading a photo to flickr. When I tried to upload a photo to flickr using the new flickr button in Aperture 3, even location data from “Places” wasn’t included. Commenter Connor had the solution: I needed to check that checkbox in Aperture’s preferences web tab (see screenshot below). Previously, I didn’t bother to look at this tab because once I opened it, I just got an error message saying “Your MobileMe account configuration is not correct.” Once the location checkbox is checked, the flickr upload button exports location data from Places to flickr.
I still haven’t been able to upload a photo to an existing set or collection on flickr. Aperture 3 always creates a new set even if I enter the name of an existing one. Choosing different values for the “Check for new published photos” even crashes Aperture 3.
