<p>I've got a 776 x 1024 photo taken with an iPhone5 (72DPI). The composition and color are fantastic, so I'd like to print it in a large format. I'm hoping to go as large as 30" x 40" printed on canvas. <br /><br />Is there anything I could do to improve the resolution so I can print it that large, or is it just not possible?</p>
