hmm weird my second post didn't make it, I understand the whole dpi when printing and all that, I was just wondering what people personal preference on the dpi when using such a large image size. Cause I wouldn't assume you would have a 300 dpi on a 10,000x10,000 image, but on the reverse side if you are using that big of an image do you lower the dpi down a lot (say in the 40's 50's instead of the standard 72)? Thats really what I was getting at
