What is the maximum size prints from a Digital Rebel?

[cgratti]

Just wondering, what size prints would be the maximum from a photo taken with the digital rebel. Im talking great quality, no pixelation... Or a professional look....

It's big!

Larger than my printers maximum of 13" X 19".. a lot larger...

I was able to rescale 1MP cropped image from the dRebel to 8x9in at 240dpi in PS and after some sharpening I printed it in an Epson printer at 2880x720 in photo paper, and the resulting image was very good, with no visible pixelation and good definition, so I assume a 16x24, or even 20x30 print using the whole image can be done without problem. Of course you can make much larger prints for public displays, because usually in larger ones the distance between the picture and the observer increases.

So I can get a real nice quality 16x24 print from it?

without any problems or manipulation?

As i've said, you need to upsample and sharpen the image, but if the original image is sharp enough (i've used a 28-135 IS) there is no problem. I've used a RAW file as the original one, but the upsampling was done using the resulting PS quality 10 JPEG file, so probably a JPEG/Fine image will react the same way. Probably a straight from RAW upsamping will allow even greater print sizes.

Simple print quality measurements, like DPI, vary in what different people call "good" or "excellent".

A print of 4"x6" is intended to be viewed at arm's length, so one standard may apply there such as 300 DPI.

A print of 8"x10" is intended to be viewed from slightly farther away, so the standard may reduce to 200 or 250 DPI.

Then 11"x14" prints are farther away, and 16"x20" prints are farther away still, so the acceptable limit keeps changing.

A RAW image from a Canon 6.3 MP sensor ought to be able to do a nice print at 11"x14" or 13"x19" (which is as far as I've gone). If you did some careful interpolation and refinement, 20"x30" should not be a big problem.

I just completed a 20" x 30" color print using a raw image at 300 dpi and it came out absolutely terrific.

I have an Epson 2200 and printed an image at 300 dpi at the printer's maximum size of 13" x 19". The print was very good. I wanted to see how far this image could be taken.

The 20 x 30 is very sharp viewed at a distance you would hold a 4 x 6 and it was printed off the college's wide printer. The college's charge at student price is $15 for a one up print

I am very happy for the quality and the price.

We should all be so lucky.

Now, get the college administration to hang your photo in their main lobby.

Whenever someone asks this question again, I always come up with this link: http://www.nyphotographics.com/blowupsample.htm

These people print large posters from images made with the D30, which has only half the number of pixels of the Digital Rebel...

Have a look here http://www.nyphotographics.com/ftppage.htm for the Photoshop interpolation actions they use to produce such posters.

I am a college student, and get all my prints FREE..

Up to 20X30"

Thats why I'm asking...
