I'm hoping one of you PS geniuses can help me. With all the web work I do, I have always thought that something that was 72dpi would be low res and suitable for veiwing on the web; anything that was 300 dpi would be good for printing.

Its come to my attention that with my new camera its set to 10mpx which is 3680x2760. I've printed a few and they look great in 4x6;
when I open them in photoshop they do indeed say 3680x2760 BUT they say 72 dpi. Why would it say that when its clearly not low res?

Thanks as always.
