miles_clark2 Posted September 21, 2008 Share Posted September 21, 2008 Why is is that when i process my images using photoshop RAW from my 40D they come out at 240dpi and not 300dpi. Is there any way i can change this on the camera so i don't have to change it on all my shots when i get into photoshop? Thanks Link to comment Share on other sites More sharing options...
kari v Posted September 22, 2008 Share Posted September 22, 2008 Why do you need to change it? Only the pixel dimensions matter, dpi is just a handy way to check how big you can print. Link to comment Share on other sites More sharing options...
chrisjb Posted September 22, 2008 Share Posted September 22, 2008 The camera is fixed at 72 normally, check the preferences in your RAW conversion program :) just saves one step in workflow Link to comment Share on other sites More sharing options...
jimstrutz Posted September 22, 2008 Share Posted September 22, 2008 240 dpi seems to be what Adobe (ACR and Lightroom) defaults to. Change it if you want, but it is mostly a meaningless number. As Chris said, 72 dpi is the default coming out of the camera. At least with jpeg images. But that is a meaning less number as well. Link to comment Share on other sites More sharing options...
tim_brown26 Posted September 22, 2008 Share Posted September 22, 2008 "Change it if you want, but it is mostly a meaningless number." And if he <i>was</i> intending to print these? Not so meaningless then. Link to comment Share on other sites More sharing options...
jimstrutz Posted September 22, 2008 Share Posted September 22, 2008 Actually Tim, even when printing it would depend on the mechanism used to print. A lot of software and hardware that is used to print ignores the dpi rating of the file completely. All it wants to know is the output size requested, and it fits the pixels into that size, essentially altering the file's dpi on the fly. It doesn't matter if the file is 72 dpi or 300 dpi, it comes out the same. That said, there are some programs that accept the dpi indicator and print that size unless you tell it to do otherwise. I still say it's mostly a meaningless number. Link to comment Share on other sites More sharing options...
pturton Posted September 22, 2008 Share Posted September 22, 2008 In the ACR raw converter, click on the blue and underlined text at the bottom center of the ACR screen and change the parameters as needed. ACR will recall the last set parameters when it is started. In Photoshop, under Edit, Preferences, Units & Rulers, set your Print Resolution and Screen Resolution as required by you output and monitor. If done correctly, PS will display your images at actual print size of your output when you select View, Print Size. Link to comment Share on other sites More sharing options...
miles_clark2 Posted September 22, 2008 Author Share Posted September 22, 2008 I work as a graphic designer and for my files to be printed they have to be at 300dpi or there abouts! I've never heard of a printed changing the dpi for the size of the print it must loose quality! Thamks for the info guys, i'll have a look in my prefrences and if nothinf turns up then i'll just do it the old fashioned way. www.fullframegraphics.com Link to comment Share on other sites More sharing options...
