Point taken, like my wife always tells me I tend to start in the middle. I just pretty much figured you always start with whatever size image you want. I guess I didn't really think of that as resolution (although I'm sure that's what it's under on my monitor settings). To me "Size" has nothing to do with clarity which in my mind is based on resolution. Maybe I'm just boggling over definitions.
So here's a question, if the Universe goes on forever can we tell what resolution it is? Hehe, I hope not because then I can walk around asking people, "So, hey, what do you think the resolution of the Universe is?"
Hmm, now that I think of it, you could start with a 2" x 2" square and create a map, then create another 2" x 2" square to connect together and so on, thus gradually 'quilting' a world as large as you like. What resolution would it be? I guess you don't know until you are done? Or is it defined by the 2" x 2" square you started with? Bah, it's a miracle I can function.
