Hi,
Just wondering if someone can point me in the right direction.
How can I find out how LARGE a photo I can get out of a digital file before it starts getting too blurry?

I don't know if these numbers help:
Width: 3264 pixels
Height: 2448 pixels
DPI: 180
Taken by a Canon PowerShot SD1100 IS

Do you know of any good services online that do this? A place that would actually help determine how large it can get. Not just a "no-service" place that prints the size you ask for.

Thanks,
RB

Here's one calculator. Scroll down and use the bottom one:

Thanks Richard.
Bummer though. 18x12! Tiny.
I guess I need a better camera. But it's too late for what I wanted :(
Useful calculator though. Thanks.

With a well focused image you can go way bigger than 18X12. Probably 36X24 at least because of viewing distance. On top of that a good printer can upsample/downsample your image for you to squeeze some quality out of it. Don't give up!

The issue is going to be the small sensor in the SD1100.

I had an image blown up to 4 foot by 6 foot of a fighter jet taken with a Canon 1D Mark II 8mp camera (same megapixels as yours) and the image looks great from 5 feet back. Stand on top of it, or get soo close that you cannot see the entire image and you can see some break up in the print, but even then it is still amazing.

Best thing to do it print part of the image on your desktop inkjet if you have one at home the size you would like it. For example if you want a 24x36 print, print it that size and you will only see a portion of it on you 8.5x11 printer. This will give you an idea of quality.

A real print shop is going to use software and or hardware to scale your image up and will do a better job that what you see at home. You could rez up the image in your editing program like Photoshop or Elements or even free GIMP.

Anyhow I bet you can make a decent size enlargement, the biggest issue is that damn small sensor in your point and shoot camera. They are great for small prints and at times can be blown up quite large if everything is perfect.

Time for a DSLR, even if it is a small cropped sensor DSLR.

Thanks for the good info Canonian.
I don't have an inkjet, just a b&w laser.
Is there anything inbetween the point and shoots and the 500 buck DSLR's I'm seeing on Amazon?

Are there any good reliable online print shops that you know of?

Not really, there are more expensive P&S! A good used DSLR would do the trick. Remember you have to want to carry it.

There are tons of online print places:
