How big can I print and still have a good quality?

I have a canon 5Dc 12.8MP (4,368 x 2,912 pixels) and I wishto take some photos and convert them into a canvas or something around 20" X 30". Is this possible? If not, is there any way to optimize the quality of the prints?

Thanks a bunch!

I haven't printed at that size but, from what I know, canvas should give you great results. In fact, you can print some great 5D images on large paper as well. You can "check" things by either cropping a portion of your image that would "approximate" a portion of a print -- say an 8x10 portion, and print an 8x10 and, viewing it at what would be a "normal" viewing distance you can get an idea of how it will display. Assuming the basic image quality is good, you should come out fine.

And, canvas is known to be quite "forgiving" with fine detail. I wouldn't use something that has focusing or blurring problems myself, but I've seen excellent large canvas prints of images taken with sensors with "smaller" resolutions.

Nooby question: what is the difference between a canvas print and a really large regular prints?

Canvas is a type of fabric that you print on, like a refined version of sacking material that your grandparents used to buy potatoes in, it's stretched on a frame. Photographic paper is made for printing photos.

It depends upon how far back (or how close to) the print you are viewing from! The human eye can resolve to only about 0.5 seconds of arc. If you make a print 10x as large, and stand back 10x as far, the 80"x100" print from 100" away would appear to be identical in quality to viewing an 8x10" print from 10" away!

Here is a post about detail resolution and pixel count, and their respective contribution to perceived image quality.

Thank you. So I suppose the canvas has a lower IQ than the Photographic paper? So is the Photographic paper more expensive then?

Photographic paper's a lot cheaper. It's easier to work with, and the volume's a lot higher. It's just the paper that photos come in, matt, glossy, or lustre. I use lustre, mostly because that's what my lab recommends.
