I sure I'm going to be proved wrong by a printer-savy, but almost for the academic exercise here's my logic:
If the recommended for 8x10 is 5mpixels or 2000x2500, for an image double size if would be 4000x5000 or almost 4 times the size of your image. But the advice I always read is that the larger the image the more distance you put between yourself and the picture so you might be ok with less DPI. And that would explain why in this website the recommended is for 16x20 is 3200 x 2500 or a little bit more than 200%: http://www.digicamhelp.com/processing-photos/printing/print-size.php On 7/24/07, David J Brooks <[EMAIL PROTECTED]> wrote: > I can't seem to fiqure out the math on this and don't want to quess, > but can anyone tell me what size i need to uprez a 2000 x 1300 file to > print 16x20. > > If a 2.74 D1H file can be resized that big. > > A client wants this size for her company wall. > > Dave > > -- > Equine Photography > www.caughtinmotion.com > http://brooksinthecountry.blogspot.com/ > Ontario Canada > > -- > PDML Pentax-Discuss Mail List > [email protected] > http://pdml.net/mailman/listinfo/pdml_pdml.net > -- http://www.flickr.com/photos/ferand/ -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
