How large can I go with 10D?

Hey guys,
Thanks to all who answered my resolution question.
Now I have a more specific question.
So is it possible to make a poster size print from the 10D and keep good quality?
I have a flower shot that I've used a mosaic mask and wanted to have it put onto canvas for a family member, but the shot would have to be pretty large.
I figured that since it was already mosaic and kind of artsy, that it wouldn't matter too much if enlarged on canvas.
What do you guys think?
Thanks

I recently took some shots at the Montreal Grand Prix and did some significant cropping on the images. I sent them to a digital lab and they printed them on 12X18 and they were deadly sharp.

Without any cropping and assuming that you were shooting in good lighting conditions you should be able to go to poster size.

SSIM,
What resolution would be needed?

I personally have only done 13x19 but I have heard of people printing 20x30 and saying how wonderful they came out. If I were you, I would check out this site. The free action might help you to get a better enlargement.

I just did a 35x25 at a sign shop where they used a Mimaki 720dpi inkjet printer and was amazed with the results. The owner of the printer said he had never seen such a sharp photo come out of that machine. Yes, it grained up (expectedly) at that size, but for a poster, meant to been seen from several feet away, it's absolutely awesome!

It all depends on how/where the picture is being viewed. Heck, people produce very successful billboard photos with 3 megapixel data.

Hi,

I did several 20"*30" from my 10D pictures. They look really great. Here is the way I do them:

- reduce sharpness of the original picture

- set printing resolution between 150dpi 255dpi

- enlarge to 20"*30" or whatever exact you want

- use the USM to sharpen the picture again

- use the contrast kurve to enrich the contrast of the picture again

- print it on premium photo glossy paper (255g/m²)

The grade of the sharpness reduction, the printing resolution and the USM parameters are variing depending on your printer and on your picture (architecture is easier to do than landscape or portrait).

Enjoy.
