This is the default dpi, which is seen as the standard display resolution.
This will not affect the image quality of the image, the resolution of the camera will still be so many megapixels regardless of the display resolution.
I'm having Sony dsc w55 digital camera. how can i increase photo resolution(quality)? currently all photo captured by 72 resolution. i want to increase 72 to 150 or more than 200 resolution. is it possible?
