however, if you change the ppi the print will be different.
Changing the PPI tag in the image file is *not* what changes the print.
yes it does.
Poor nospam. We can post 30 different identical copies of an image file, with only the PPI tag being different. Anything from 7 to 7000 will do. When loaded into an editor... the image data will be exactly the same for every one of them.
that's what i said originally, then you said ppi applies to displays. now you say it doesn't. hilarious.
You are the only one claiming that, not me. You obviously haven't got a clue!

Until you print... or display an image on a monitor screen. Same thing, and a different value for DPI/PPI.
Each and every monitor operates at a given PPI. So does each and every printer.correct, however display ppi is no longer relevant since modern operating systems no longer map it 1:1.
The tag in the image file,correct.
1) has no effect at all on the monitor, and
2) has no effect at all on the printer, anddepends on software used to print.
3) has no effect at all on the editor, anddepends on software used to edit.
4) has no effect at all on the image.correct.
it does.Floyd L. DavidsonBecause chaning the PPI tage in the image file does nothing.nospam
it does when printing, which is what i said.
It doesn't do a thing.
Set the Exif tag to 72, 360, 720, or 7200 and then tell the print driver to make an 8x10 print. It will, but it will run at it's own PPI rate, not the one set in the Exif tag.setting the image ppi to 7200 results in a print that's 1/10th as big as if it was 72. or to put it another way, printing at 1/10th the size sets the ppi 100x higher than it was before.
once again, you aren't using the software other people are using, yet you tell them how it works. that's really fucked up.
