Skin with Porta often ends up looking like everyone is wearing a base layer of make-up. People's face just have more definition and imperfection than shown with it. A lot of the Olympus lenses already cause this to happen so you combine the too and for me it is just too much.
Perhaps others would not describe porta as being cooling, but to me it appears the amount of yellow in it is reduced a far bit. It has a very "white" look to it as white is too strong with it.
If this was Porta his helmet would of lost a lot of definition along with one side of his face.
