How do you change the Sony Cybershot DSC-P10 settings to capture images that are 300 dpi?

Question

Is it possible to change the settings on this camera to reflect a high-rez photo?

Answer 1

Cameras all have a default DPI setting - different for each brand - but you can override that setting in an image editor when you make prints. That's all the DPI setting is: in instruction for the printer. DPI doesn't say anything about the quality of the picture file itself.
The Sony DSC-P10 is limited to 5-megapixels, with a maximum resolution of 1944 x 2592.
At 300 DPI, your prints will be:
1944/300 = 6.5 inches by
2592/300 = 8.6 inches
If you settle for a tad less DPI, you should still be able to make fantastic 8x10 inch prints.

Answer 2

It's not the camera that determines the dpi, it is the software you use to open up the photo file. Generally, photo editing software will default to 72 dpi.
