I need someone to explain this to me, I've been doing a lot of research but I'm still confused.
If I understand this, when you take a picture witha digital camera, no matter what resolution setting you have it set at, it packs the same amt of pixels into the image.
But why if I take a picture at 600x800 can't I increase the size of the picture without losing image quality? If the same amt of pixels are in that 600x800 as would be in an 2160x1440?
I don't get it, you can scale down a large resolution picture and not lose quality, if you have a camera with sufficcient pixels, why can't you scale up?
Thanks for the clarification.
edit: Whoops, wrong forum, sorry. Please respond anyways
