Photography is not an easy thing.The second one is an A1 I got printed from my old 40D with some cherry blossoms which looks nice. For both these the canvas has done pretty well to both give a bit of texture to the subject but also cover up imperfections from the low res crop sensors. I know a website which is really good for printing. They renders a great service for digital printing . You can visit the website http://www.digiteksf.com
