I think Yin and Yang are a lot simpler than we make it out to be. Lets start with the difference between Yin/Yang Chakras and Spiritual/Physical Enegies.
 * Spiritual is energy of the mind. It is by extension Yin because Yin Chakra doesn't exist without it. So all Yin is Spiritual but Spiritual isn't necessarily Yin
 * Physical is energy of the mind. It is by extension Yang because Yang Chakra doesn't exist without it. So all Yang is Physical but Pysical isn't necessarily Yang.

Yin in its purest form, is Genjutsu. I think Nara's shadow techniques, though Yin, need a tiny bit of Yang to make the shadows have a physical presence.

Yang manipulates the physical, like Multisize and Calorie Control(?). these techniques maybe need a tiny bit of Yin on order "guide/control" the transformations. For example, Multisize would just stretch you until you exploded and became a bloody stain. In it's purest form I think it is vitalization, in oneself or others.


 * So let's switch somethings around. If Multisize was Yin Release then would have the ability to turn body parts into tentacles or other materials.


 * If the Nara's Shadows were Yang release it would turn the shadow into a physical object that would need shape transformation to not just be a super thin black silhouette on the ground.

Yin-Yang is using both at the same time. It creates something real and physical from nothing at all. Its the same Concept as Izanagi, but better. The wiki has it listed as a Yin and Yang but not Yin-Yang, so I am assuming it creates the illusion, then makes it real, while true Yin-Yang just makes things on the spot.
