Hi Folks, Been itch'n to buy a DSLR. The one in my price range that works with my current lens is only 6 megapixels. Where I want to take digital photography and photoshop is into the fine art arena. I don't want my images to be burring, but since I'm printing on archival matt paper and canvas, I don't need to be super sharp either. Questions is, how large can I expect to be able to print and still get a decent image with 6 megs?
