Okay then, it's a digital zoom. But it's much better quality than a digital zoom because I'm not scaling it up. Digital zooms are rubbish.

Funny, I tried to write a word that means the opposite of...

I'm still not 100% sure what this means. Are you saying that cropping a 2272x1704 photo down to 1280x960 is not the same as a 3x zoom?

How can that...
