In the e3 movie, the scene in the lab with the scientist and Alyx shows a magnifying glass. It appears to be magnifying the scientist's hands typing on a keyboard.

Looking again at this movie, I am wondering if true refraction was used to create a magnifying lens, or if it was "cheated" (term used loosely, please don't flame me).

By "cheated" I mean an invisible camera sitting about 20 centimeters (around 8 inches) behind the glass, and the glass of the magnifying lens just displaying what the camera sees.

If they did "cheat" this, then I don't consider it a bad thing. I'd consider it a good resource saver.



But if it isn't "cheated", then I theorise a weapon mod for a sniper rifle where the scope is fully functional: this means that when you click zoom, the camera moves to behind the scope and looks through it, using true refraction to calculate the zoomed in view.
