Work away to come back.

Always be looking to when you can have your face away from the camera. 

Your first impulse might be to give your partner all your attention and look them in the eye.

Decide what suits and is most useful.

Looking away means you can look back. Opposites. That back and forth really suits the frame.

It’s the old idea in art of disappearing to reappear.

You need to be in thought while acting on screen. Looking down or away is screen language indicating thought. Playing truthfully will produce it.

And knowing how to do it technically is professional.

Where you’re looking can signify how much attention you’re giving the other character. You’re always in the situation, but you don’t always give a hundred per cent of your attention.

When the other character gets all your attention you’ll look back at them - eyes close to the frame. 

This sweep into the frame helps make your point. It’s smart use of the medium.

Ebb and flow is sweet on camera.
