Why is it, then, that 80% of all editorial images sent to me by professional photographers are set to 72dpi?


Who cares ... THIS IS A MEANINGLESS NUMBER!!!

What matters is only the number of pixels.

Let me repeat that: NOBODY SHOULD CARE.

If you want a picture that is 1x1.5 inches, and have the
resolution at the printer to use all your pixels (i.e.
you are printing to Kodachrome!), set the dpi accordingly.


If you are printing to 8x10 (feet that is ... ) set the
dpi accordingly.

This is not rocket science.

I once had a publisher insist that I send the ORIGINAL IMAGE
dpi ... this was a scanned image, and he wanted the
scanner dpi. So I did. It was 508000000dpi. (yes, apparently
jpeg can handle this.) However the image was 256x256 pixels ...
not exactly high resolution.
