No clue. A+ paper size is 13 inches by 19 inches. As far as pictures go, that's an odd size for an actual print, and would be considered custom, therefore making it expensive to both print and frame.
The closest standard print size to A3+ is 11x17, then 11x14, 8x10,5x7,4x6,3.5x5, and 2x3 (all sizes in inches). Printing at 300 dpi, you should be able to crop your raw image at 11x17, and not notice any drop in quality, as raw size as you stated in your post is 16.54x11.02.
On a high quality professional printer, and with an image that is exposed correctly, then you shouldn't notice the difference when printing between 212 dpi and 300 dpi. If you are doing this professionally (ie selling your prints to customers), then chances are the guy that works at the local deli who is buying your print isn't going to notice that you've printed at 212 dpi instead of 300 dpi.
Also, you probably won't notice a diference if you shot in raw then cropped and saved as a jpeg (saved on the highest setting) and made a print.
How cannon comes up with their figures is beyond me. I know this doesn't answer your question, but hope it helps to put your mind at ease when it comes time to make a print. _________________ All gave some, some gave all.....Lest we forget that war produces veterans, wounded both mentally and physically, and it is our job to help them now, as they have already helped us all in ways we will never know, and in ways that we take for granted every day. |
