I have my oAuth authorization with Picasa working and I can fetch all the albums using access=all, however when I change my access to 'private' in the following URL I'd expect to get my private albums. I get all my hangout albums (with limited visibility) instead.
https://picasaweb.google.com/data/feed/api/user/default?kind=album&access={access}
According to the documentation there are 3 possible values. 'All' returns everything and 'public' returns only my public albums (as expected). But I was wondering if the switch to Google+ Photos perhaps included another parameter that was not mentioned in the Picasa API documentation?
Also would it be possible to retrieve my public and private albums, but not my hangout albums?
