I just got a Canon 40D and the software that came with it is installed on my computer. I have the camera setting on highest quality images. When I am downloading and saving the pic files to my computer, the dpi reads as "72". I guess that is technically ppi, but most pple say dpi, even my publisher.

The publisher assumes my images are 96 dpi and when I receive photo files from outside sources, they are 96 dpi. Why are they coming out as 72? I know I am a greenhorn about this camera, sorry.

I do have Photoshop and can change the images so they are suitable for publishing at 300 dpi, so I am OK with that process. Just wondering where that 72 came from and if there's some setting on the camera I should change.

DPI and PPI are two different animals. Here is a site that gives a pretty simple explanation of the difference.

Hope that helps

Thank you for the response. Yes, I understand what you are saying about ppi and dpi. It seems that most people I deal with, even publishers, continue to use the term "dpi" when they are actually referring to "ppi," so depending on who I am talking to, I just use the terms they like best. When I worked for a newspaper in the pre-press department, dpi referred to the screening process.

My camera, a Canon 40D, is brand new, so I am assuming that the 72 ppi it produces, rather than the 96 that was the standard, is a good thing. I was reading on the site you led me to that lowering the ppi increases the print size.

Anyway, thank God for Photoshop.

Your camera doesn't produce 72 dpi (or 96 dpi for that matter). It produces an image that is 10MP - 2592 pixels X 3888 pixels (portrait orientation). You can view (and/or print) those 10MP images at 72 dpi, 96 dpi or 300 dpi in your software of choice - that's up to you.

Exactly. Your publisher could even change it himself.

Or the so called "publisher" could try getting a clue...total idiot...

At this point, is there any excuse for this level of ignorance form a supposed "publisher"?
