dpi resolution

Hi , I notice whenever looking through the properties on flickr that most of the files from canon 30d are showing a resolution of 300 dpi in properties yet all mine taken from a 30d only show my resolution property as 72 dpi , how can I get my dpi up to 300....
thank you,
Kimmy

I think that is more about how the file was saved. On your Canon 30D, what file-type are you set at for your pictures? (e.g., in the Menu). If you are set at LARGE JPEG, you should be getting much higher DPI, at least mine does.

Kimmy,
DPI is a meaningless number. Ignore it and enjoy a happier life.

I am set at the largest jpeg highest qaulity setting eg fine....

The default ppi in most cameras is 72. Don't confuse ppi for dpi, we don't care about dpi. When you download the pictures they will still be at the default 72 ppi. When you process the pictures you will want to resize them to somewhere between 250 and 300 ppi. This depends a little on what you are going to do with them. If you are printing you will want around 300 ppi at whatever size you are going to print.

Where are you seeing the DPI - flicker? Could be that THEY are reducing it in DPI for their web hosting. For instance, when I open mine in Photoshop, the DPI is not obvious until I try to save-as-jpeg .. then I have an option of the DPI value. When I download from my camera to my local machine, the file size is typically 2-3MB for "FINE" jpeg images that I've taken.

Second this!

Cody, dots per inch (DPI) is a printing term, it has almost no value in capturing photos. Pixels per inch (PPI) is the one we care about. This is the actual resolution of your image. A 10mp camera captures images at 3888 pixels wide by 2592 pixels tall. At 72 ppi that gives a native size of 54" x 36". But we don't care. During the post processing you will general resize the image to size it for printing or screen viewing. Reducing the overall dimensions of the image to about 12" x 8"; give or take depending on what you want to do with the image. When you cram 3888 pixels into 12" of width you get 324 ppi.

But it still doesn't matter. This is all based upon the native resolution of the camera and does not take into account that you will be cropping the image to change the aspect ratio and that you will probably be resampling the image to get to whatever ppi you want.

thanks for clearing this up eric, et al...
