I tend to need reading glasses these days. It’s not so much a problem with shooting but reviewing on the back of the camera has to be at arms length or wearing my reading glasses. So i was thinking about a diopter for the lcd screen and a diy version at that.

Anyway I was holding my reading glasses about 8″ away from the little screen and looking through them and and thats when i realised my photo’s looked 3D!  well not all of them some the subject was a little out of focus and it doesn’t work then.  But it does work and its so impressive.  I think your brain takes the 3d cues in the photo and because things shift a bit though the glasses the photo’s just come alive.
