| Ok so assuming I have an uncropped 3072 x 2042 picture, and I want a 30 x 20 print, do I need to enlarge it with a fractals program in order to get a decent result? I've seen prints on dpcprints that have been 20 x 30 but I understand that there is a 150dpi limit. How is this possible? Am I just missing something? |

| 150 DPI is the minimum DPI in order to make a print available on DPC. 300dpi is the usual standard for a compromise between quality and size. 300dpi is considered "Outstanding" quality on DPCprints which is the highest quality available. |

| Typically you will get better results if you resample. You'll probably have to resample anyway for a 30x20 print. You certaintly don't need to spend money on a program like Genuine Fractals to get good results. I've done some tests and if you do it right in Photoshop there isn't a substantial difference at all. |

How clear do you want. My uncropped prints 2288 pixels by 1712 pixels are 31" by 23" according to PSP7, I'm not sure what kind of print quality you get with that, though.

Resampling quality is, of course, device dependent. Assuming you're okay with the device resample quality, you don't have to do any work (hooray!). If you want to have finer control over print results (like sharpening for example), you'll want to resize to (one of) the printer's native/preferred resolutions.
For a print that size (20x30), use 254 DPI (on dpcprints that is).

You could also order a test print for yourself with the unsampled image (at about 100 dpi as you have it now). You just couldn't put it up for public sale through DPC Prints at that size.
The effectiveness of the upsampling is largely related to the type of image; those with large areas of smooth color will upsample more successfully than those with lots of detail. However, the admins should let you know if the upsampling works by accepting or rejecting the image, so there's no harm in trying. |

photoshop CS is a pretty good way to upsample. you can always upsample your image and loook at the 100% view and see the effects.
