I hate Canon cameras because the photos are only 72dpi, yet Nikon is 300 or more.

DPI is short for Dots Per Inch and it actually refers to printer dots per inch. These days, when used in photo software, it means PPI, which are pixels per inch. ... If the pixels of an image do not change, then it has the same digital resolution no matter what number is parked in the DPI/PPI setting of the photo.

Canon 72dpi

Nikon 300 - higher dpi

Panasonic 180 dpi

there are standards with DPI:

• 72 for computer screens
• 300 for good quality printing
• 400 for high quality printing
