getting models to look directly into the camera (pics)

From my experience and I would say others.

I would say it's up what you shoot if you shoot couples 2 girls or boygirl they should not look at the camera. They are there for each other to have sex.

If you shoot single girls i think is very important that the girl look at the camera, but the correct way. She is seducing the person she looking at from the picture, not looking like she waiting for bus.
