| How large can you make a picture taken at 6.3 megapixels? I have a nice shot i took, and want to make it as big as possible without a noticeable loss in quality. If it helps, i took the picture with a 300d |

Depends on how far away you will be looking at the image. You can probably print out a billboard and not notice much quality loss if it was 25 stories on top of a building roof.

| I recently got some 16x24" prints done with dpc prints and they look amazing (taken with 300d) the print with a picture taken with the 50mm II is incredible.. I also got a 20x30 of a waterfall (the image is a bit softer than the 16x24's though) |

If you've got the original file just push the dpi up to 300 and you should be fine.

Do you always upsample the pictures to 300 dpi? I've not dome much big pirnts but I gess for very big prints like 20x30 the combination with not much upsampling will give good results, for example 150 or 200dpi. Because if you don't have a specific program or aren't carefull the upsampling can bring up a lot of artifacts.

Well I didn't understand everything you said :P but yes I always push the dpi up to 300. Although I've only done one print in 20x30, that one looked perfect and had no signs of artifacts.

I ordered a 16 X 20 from DPCPrints of an image I took with a 3.2MP camera and it looks GREAT so I would think you would do fine with the 6MP Camera.

I have Sony F717 (5mp) and ususally I print images on 20X30cm. Quality is good. I even tryed to print 30X40, and it was good too. It occurs what you whant to print. and one more thing is light. if you have good lighting contditions, you can get 30X40 by 5MP without any problems.
I use Adobe Photoshop CS2 to enlarge photos up to 30X40cm 300dpi. And ususally I print images in Kodak Profoto or Konica labs.

I think they are reffering to 20X30 INCHES... |

| I have printed upto 20x30 prints with Canon 10D (6.3 MP) and it looks good even at 150 pixels/inch. (3000x4500 pixels imagee). this means you will have to upsample 50% |

To determine the largest size a picture can print, you divide the size in pixels by the dpi you want to print at. You can get a decent print with as little as 150 dpi, though 300 is preferred. So a picture at 3000x2000 would be able to be printed at 20"x13" at 150 dpi or 10"x6 1/2" at 300 dpi.
Changing the dpi of the picture does not create quality loss because it is not resizing the actual picture, just the printable size. Resizing the pixels can create the quality loss. In other words, if you want to take the above 3000x2000 photo and hold the dpi at a constant 300 dpi, but want to make the photo print out at 20"x13", you would have to resize it to a 6000x4000 photo. However, if you drop the dpi down to 150 dpi, the photo remains 3000x2000 and the photo will print out at 20"x13".
