From the parent (top level) Album you have have Nested Albums can go to 14 levels deep. Then on any given level you can have as many Nested Albums organized there.
In this example, there are a total of 6 levels shown. "All My Vacations" (level 1) > "2014 Vacations" (level 2) > "July" (level 3) > "Visiting In-Laws" (level 4) > "Day 1" (level 5) > "Drive to In-Laws", "Poolside Fun!", and "Volleyball Competition" (all three are level 6).
You can continue down until you reach a total of 15 levels for any one Album. Then within a single layer there can be as many Nested Albums - like for this example you can have several decades of years on level 2 or split the day's activities even more on level 6.
