I'm a photo hobbyist experienced in doing my own b/w darkroom printing enlargements up to 11 x 14 from 6 x 7 cm negs. My quest was high detail, low grain prints. I would like to maintain these qualities when I transition to digital printing with enlargements as large as 13 x 19 in with either b/w or color. What are the opinions of this forum's members about images produced in a 12 MP camera maintaining high detail and low noise comparable to what I got in the darkroom when the digital image is enlarged to 13 x 19 in. I accept that top-of-the-line Nikon/Canon lens quality is a must. Would I need a camera with a full size imager or would the smaller size be sufficient saving me big bucks. I know that your opinions are subjective about what would be acceptable print quality, but I have no experience beyond my 3 MP P & S enlarged to an 8 X 10.
