Okay, I was assuming that there was no parallax error in digital cameras because I thought the image you saw on the screen, even in macro pictures, was the same as the one that was taken (as opposed to using a viewfinder-or whatever you call it- with a regular camera, where there is a difference in angle between what you see and what's recorded).
I stand corrected. But I still don't understand why the images (seen and recorded) wouldn't be the same in a digital camera. There shouldn't be a difference in angle.
I'll have to test this out next time I get my hands on my mother's Nikon CoolPix 4500.
