D800 and iphoto
As far as I know, all photos reside in an Event as well. Events are just for sorting purposes, kind of like folders with your files in them (but Events are virtual folders so to speak, your files are not organized physically on the HD by Events). Probably your problem is that they're loaded into an exisiting Event rather than creating a new one?
