Thanks! I would have NEVER realized those numbers were bolded! I was mainly working with ribs and top and the 7 REALLY doesn't look different from the 0!
Ok, so I got that you use the flashlight on the camera and have a pencil in the middle and the shadow will fall on the number. However, the camera and flashlight on my moto is in the middle and not on the side, like in the picture, and I think it is causing me to get the wrong numbers.
