Need help understanding the DPI of my photos?

I just now got a new digital camera and I'm not an expert or anything so I'm trying to learn about how to use it. I've been taking pictures with it and then I go to look at the dpi and it's always 96 x 96. Is it supposed to be that way? I've tried changing the settings on the camera and everything but nothing changes. Am I doing something wrong or what. Thanks for all answers.Need help understanding the DPI of my photos?
This is a complex subject that is widely misunderstood. But I will try this simple explanation!



. Your camera records pictures with virtual colored dots called pixels.



. By themselves, pixels don't have size. They only get size when we try to display or print them.



. Pixel size is expressed as Pixels Per Inch (PPI). (DPI is really about Drops Per Inch of printer ink.)



. We can set PPI to any size we want, but if the pixels get too big the print will look bad.



. Camera manufacturers just set a default. Yours set 96 ppi. You can change it, but not in the camera. You have to use the photo editing software in your computer. Look for the Resize function.



Make sure that you have the Resolution set in your camera for the largest size. That will you the most pixels to work with when you want to print. You can always downsize with the Resize function if you want to make a smaller image for emailing.

DPI (Dots per Inch) is how inkjet printers level of quality are measured. It has over the years defined the quality of images on a computer screen, the minimums set to guarantee non-pixelated photographic prints, just to name a few.



Generally you want to shoot the original image using the highest quality image and then adjust to specific needs later using a photo editing program.



The generally accepted max resolution that can be seen on a computer monitor is 72 although theoretically, there are some monitors that will resolve 96.



The minimum recommended DPI setting for images that are going to be printed is 300DPI and up. DPI values can usually be adjusted using a photo program, sometimes with the program that was shipped with your camera ... but not always. Most cannot afford to run out and purchase Photoshop CSII or CSIII, so we can purchase Adobe Photoshop Elements 5 and get about 99% of what we need when editing our photos.



I can only speak from my experience with Nikon DSLR's, so here it goes. To get the most resolution from a JPEG image, you first have to set the image using the options in the Menu to Fine and image size to Large. These two settings are usually (but not always) the way you can control the quality of your images ... in camera.
