I have photos that are rotated within a photo stream created from a project even though the photo displays properly within the project. How can I get the photos to have the proper rotation within the photo stream?

Question

I have a photo stream that was created from a subset of photo from a rather large Aperature project. Some of the photos show up rotated within the photo stream but are not rotated within the project. Why is this happening and how do I fix the rotation within the photo stream? I do have the latest version of Aperature and have all of the necessary updates applied to my devices used to view the photo stream. The photos do show up rotated within the photo stream segment of Aperature, so I am sure it is not an issue with the output device (iPad and Apple TV). I do know that I cannot edit photos within a photo stream, but no amount of editing within the project allows the photos to be properly rotated within the photo stream. All help would be greatly appreciated.

Answer 1

That will work, but it is the long way 'round.
As Frank noted, Book Albums are just specialized Albums.  Albums can show any Image in your Library, regardless of where the Album is located on the Library Inspector, and regardless of which Project contains the Image.  You can put your Albums anywhere (in a Folder called "Books" for example).  You can put Images from anywhere in your Library in any Album.
The easy way 'round:
- Make a new Book Album
- Select Images you may want to put in your Book.  Flag them.
- Select some more.  Flag them.
- Go to the "Flagged" container (listed near the top of the Library Inspector), select all, and drag-and-drop them to your Book Album.
- Repeat as needed, or just drag-and-drop directly into the Book Album.
Note that you can remove any Image from any Album (including Books) by selecting and hitting the "{Delete}" key.  This _does not remove the Image from the Project that contains it, or from the Library.
Note, too, that once the Images are in your Book Album, you then put them in the Book you are creating for publication.  The Book Album contains the superset of Images with which you populate the Book itself.  The Book Album also holds the Book.
A good (imho ) introduction to the parts of Aperture can be found in this short guide I wrote.
The User Manual is helpful.  Here is
the chapter on making Books. 
From that chapter, here is
the section detailing how to create and populate a Book Album.
