You do not.  It is best performed in post processing.  The Canon DPP4 software can do it for you through the Batch process module.

That exif field is really for scanners. When you scan a 4x6 print it is good to know the DPI so you know the size of the original. Cameras need to put something there so Canon puts 72. You can use software to change it later, but it is best to just ignore it and not worry about it.

If someone *requires* you to submit a 300 dpi image, laugh at them and run away since they do not know what they are doing unless it is your printer telling you how much resolutiion you need for a certain print.

Well, you may say that, but if the "someone" is running a juried show in which you and several hundred others hope to have pictures displayed, you will not laugh, but will smile and do as you're told. Fortunately it costs you nothing (but your pride) to comply, since the restrictions that really matter are the size of the JPEG file and the actual size of the framed print (if you're lucky enough to be chosen to submit one).

B from B,

"... but if the "someone" is running a juried show... but will smile and do as you're told."

Or laugh it off as that has to be a amateurish uninformed 'show'!  Not worth submitting even if you win it.

Hmmp.  I would have thought requiring digital image files to conform to a size specification would "level the playing field", so to speak.

Size specifications are fine, and probably necessary so you dont get GB sized files. But 300 dpi is not a "size spec" it is a printing spec.

Why say submit a "4x6 photo at 300 dpi" when you can say an "image with 1200 x 1800 pixels."

And why would you reject an image that conformed to the 1200 x 1800 pixels but happened to have the dpi field set to 72 dpi.

Uh, yeah.  It is a print size specification, in this case for viewing.  You know, like characters per inch?  Quit while you're ahead.

" it is a printing spec."  Absolutely.

This is quite correct.  A photo has no dpi.  "Quit while you're ahead.", or in your case quit before you get further behind.

Absolutely.  When images are displayed on your computer monitor, they are printed to the screen.  That's how it works.
