aperture export
i don't seem to be able to "select" and export only the photos i want.i end up exporting ALL my photos.
Are you sure you only have a few selected? Sometimes it can be hard to tell depending on your background settings.
Or try this: make an album called "export" or something. Select the images you want to export and put them in there. Then select all or a few and try again and see if the problem repeats itself.
Are you using File>Export>Versions?
