For a user album you can do that:
When you create your album, you just have to add the privacy field (referenced here: https://developers.facebook.com/docs/reference/api/album/).
You can see the various possible values here: https://developers.facebook.com/docs/reference/api/privacy-parameter/
But for a page, even if you're admin, it seems you can't:
Note: The privacy parameter only applies for posts to the user's own timeline and is ultimately governed by the privacy ceiling a user has configured for an app. It does not apply to posts made by an app on behalf of a user to another user's timelines or to Pages, events, or groups. In those cases, such posts are viewable by anyone who can see the timeline or content in the group or event.
