I want to make some poster prints of photographs, but with 300 DPI (which is recomended by most photographers and printers) it won't be much of a poster (the pictures are 10 megapixels). When printing at poster sizes, lets say 28 by 41 inch/ 70 by 105 cm, how low can the DPI get? Posters aren't going to be looked at really close, but it shouldn't look reeeeally bad up close either...
I have mailed a company that prints some nice posters of the size I want, most of them are from photographs, and they're all printed at 300 DPI (so they say)... what kind of camera's do those photographers have?
they can't all have 40 MP sensors, right?
This sort of stuff gets me really confused, I would just try and print some sizes, but my budget is too limited for that. I'd love to hear from people that have experience with large prints!
UPDATE: I had some 75 x 50 cm prints made from the pics, and they turned out great
