How to get a saved 72-dpi image to 300dpi?
Hello. Is there some way of taking a 72-dpi image and somehow
squeezing more detail out of it? I've got a photo that was done at 72 dpi but the publisher needs 300 dpi to work with. As a newcomer to digital photography I tried printing the 72 at highest quality and then scanned the result at 300, but I think that the result was necessarily infreior. Any help? Many thanks. John |

Adding detail is not possible under any circumstances. The information is simply not there, and cannot be introduced externally. You can easily convert 72dpi to 300dpi, but all you'll get is a blurry or pixelized image (which is likely what you got when you rescanned). There are software packages that 'try' to add detail, but all they do is introduce noise into the image. The only way to add detail is to re-shoot, re-scan, or otherwise recreate the image at a higher dpi from its original analog source. Sorry! ;-) BD |

Where are you finding the information that it is a "72-dpi image"? With those items of intelligence, you'll get more useful answers, I think. I mean a greater number of pertinent responses. -- Frank S |

How to get a saved 72-dpi image to 300dpi?
What is the file size? DPI is a printer instruction.

No. Reshoot or rescan the photo at a higher resolution. What you did
was the equivilant of photocopying a hundred dollar bill at 300% enlargement and then trying to claim that the copy is now worth $300. Not so much. That said, if I were you I'd spend some time googling around on this topic. If you're printing things out and rescanning them with the idea that you're somehow doing your photos a favour, any publisher getting those images is going to immediately mark you in their Roladex as being mildly retarded and will probably never call you again. |

Print the image at slightly less than one-quarter its current size and
it will be approximately 300 dpi. |

How to get a saved 72-dpi image to 300dpi?
I take all my photos on the highest resolution, ( I have a Canon Rebel XT, 8.2 MP). All the photos are 72 DPI but the pixel size is something like 3400 X 2300. I also was told that the photo to be printed should be 300 DPI, but if you have a photo this size it is my understanding that printing it should be no problem. wrote in message oups.com... Hello.

The most important info is the pixel dimensions, as your software is calculating DPI based on the size that you have tacitly decided to print at. If you want to print at a smaller size, input the print size data and then the calculated printing DPI automatically goes up. Dave |
