If viewed from an appropriate distance, huge.  Billboard size.

The key is appropriate viewing distance though!

Thanks Star!

The canned answer is 24x36".

Depending on what you viewing distance is you could go larger.

If your viewing from 3 - 6 feet away 24x36 is perfect, 5 - 10 feet 30x45", 100 feet away and you can print a billboard.

I had a client take shots I did with a 40d and blow them up to 3ft x 6ft poster size.  They turned out awesome.

If your photo processor has good up-converting you can go rather large without too much problem.

as stated by someone else you can get to billboard if you want, provided yo uare viewing the images from a distance.

Here are the suggested number of megapixels to use for common print sizes. This is just standard stuff pulled from the web...

Max Print    Minimum MP    Resolution
4 x 6″    2 megapixels    1600 x 1200
5 x 7″    3 megapixels    2048 x 1536
8 x1 0″    5 megapixels    2560 x 1920
11 x 14″    6 megapixels    2816 x 2112
16 x 20″    8+ megapixels    3264 x 2468
24 x 36"    10 megapixels

I've printed 24x36 with a 6mp and it looked very good though. Also, if you crop images a lot, the minimum megapixels should be increased.

The reason you are seeing such widely varied numbers is that the subject and personal taste both factor into the issue, as does viewing distance, as someone has already pointed out. Thus there is no "magic number" anyone can cite, beyond which, like throwing an electrical switch, your image turns to mud and rocks. I've produced 30s40 inch prints from a 6 megapixel camera that everybody who's seen 'em have loved. Part of the beauty was perhaps in NOT having a similar image from medium format film side-by-side, although to be honest, even that might have lead to folks preferring the digital image. I know that a pair of 11x14s I did pitting 35mm 100 speed film against a 3 megapixel dslr ALWAYS had folks preferring the digital image.

So, between you and me, if you have a mid- to high-end dslr with 10 megapixels resolution and you take the photo right, and process it right, and send it to a good lab, I wouldn't hesitate to make any size your budget can afford in the way of a print, up to and including the earlier mentioned billboard (which, after all, is only going to be viewed from 300 feet away -- or more -- and at 60 miles an hour to boot).

I have a 4.25 MP camera and resize In PS and make 16x20's   
i also have a Billboard  made from a raw image from a d30  NOT 30D   3.25 MP. its all in the way to process it.

Agreed. I regularly sold 20x30 prints from a 6 megapixel camera, and more than a couple 30x40's. Those were portraits, though, and I doubt strongly a detailed landscape shot would be as acceptable.

It depends.

On everything, really.
The camera, the lens, the film or sensor.
The shutter speed, the ISO, the aperture.
The post-processing, the pre-press.
The printer, the ink, the paper.

But mostly, your personal taste.

Is it sharp enough for you?
Or your client, if you have one.

Isn't the correct answer: 300 px per inch?
I'm not sure but I've heard it many times. That leave us to this with my Canon 350D

I'd love to know were those numbers came from because none of them are consistent with anything.  They really seem as though they were just picked out at random.  Pardon me for saying it, but it's alot of horse-shit numbers.

For instance:
If all things were equal (same sensor type, same processor, same printing... etc) it takes 4 times the amount of pixels to create an image that's twice as large.

With that in mind, if you're getting desired results with an 8x10 photo taken with a 5 megapixel camera (as mentioned in the example above), it would require 20 megapixels (not 8) to create a 16x20 image at matching quality and resolution.

My first digital camera was an early Canon EOS with a Kodak back on it.

The actual file size was about 3.6 Megabytes when it opened up in Photoshop.

So, I'm guessing it's about 1.5 Megapixels by todays standards.

I did a shot of a model on a motorcycle that got blown up to 12 x 15 feet with amazing quality.

All I did was resize it in Photoshop and gave the client a CD Rom with a file that was under 500 MB

By the time it got printed, I was blown away with the fine detail that showed.

You can blow them up as large as you want, they won't lose any quality as they go up.

it's relative to the camera body image quality it is able to produce.  Plus, what I may find to be not a whole lot of noise might be a WHOLE lot of noise to you.

And not to even mention software or resizing.  Genuine fractals is amazing at resizing images.

I've made 30x40 inch enlargements from a 6 meg camera with no problem and with beautiful results.  A client purchased 20 in that size to decorate the walls of a new spa. None were returned and their check cleared. Two were exhibited as 20x30, or something like that, in a summer long exhibition in an Italian art museum. 

The trick is for exposure to be on the money, along with accurate focus and overall sharpness. Genuine Fractals can be a major help. It will not improve a faulty image, instead it will prevent image degradation through enlargement.

Most labs and magazines require 300dpi output.  Take your 8x10 (or whatever size) and multiply by 300dpi.  2400x3000 is correct for 8x10 at 300dpi.

I have a 44" printer so I can print big from my 10mp camera smile make sure you shoot at the lowest ISO you can make sure everything you want sharp is sharp. If you want further details I would be happy to provide them. smile

Just to restate it, someone already mentioned...

The VIEWING distance is critical to how well upsizing works.

The graphs and charts and recommended max sizes above assume you'll hang it in an average room in a frame and stand 6 feet or so away from it.  Then lean over and look closer. wink

Billboards are often printed at VERY low dpi...but they work cuz you're hundreds of feet away or more, mostly.

That's the critical factor. If you stand 6 feet away from a billboard it looks like caca.  So that's why you're getting so much varied info...

B

Edit:  Here's an interesting link to a billboard printing company, showing the photo specs for a 48' wide billboard.  You'd have to upres from your 10mp...but I bet it'd turn out fine at that viewing distance.

People tend to stand closer to pictures of landscapes than to portraits -- I always noticed that at the galleries.  With my own work I see this all the time -- people will stand RIGHT NEXT to

http://www.flickr.com/photos/epsilonima … 294687444/

and back WAY AWAY from

http://www.flickr.com/photos/epsilonima … 210512541/

... even if both are printed at the same size.

My preference (and to add to what everyone said, there are a million variables) is to keep the 10mp landscapes to 11x14.  Portraits are a whole different matter -- you can make a 24x36 and people will back up...  I wouldn't hesitate to go to 20x24.

Other than WHCC may be good in a pinch (for me) since it's pretty much free UPS overnight and my prints have a 2 day turn-around.

I do a lot of work for my church and tehy put them up on the 10'x10' projector screens all the time.  THey look great.  I do shoot 12mp, though.  I am sure that doesnt matter at that point.  More frequently are 24x36 reproductions, and they are always spot on!

We were taking an old (well new back then) Fuji S1 up to 19x25 at 300 dpi when I was back in college and it worked great.

Just have to be careful on sharpening and not over do it.

I have seen a rule-of-thumb used for distinguishing "strong" and "weak" perspective that the viewer will stand a a distance away from a rectangular image approximately equal to the diagonal of the rectangle.  This is mathematically related to calling 50 mm a "normal" focal length for 24 x 36 mm film frame.

You're right.

Most projectors only use @ 1.6 megapixels to project an image, and even the top of the line projectors (WQXGA) are comprised of a 4mpx array.
