I have a Panasonic DMC-FZ50 camera, no longer produced, but it was at the top of Panasonic's line.

SWMBO has a Panasonic DMC-FZ28 camera, considerably less expensive and not as feature-rich.

Both cameras shoot at 3648 x 2736 resolution, ~10 megapixels.

If I look at photo properties for a picture from the FZ50, it says 72 dpi for horizontal and vertical resolution.

If I look at photo properties for a picture from the FZ28, it says 180 dpi for horizontal and vertical resolution.

Pictures from either camera seem comparable to look at.

Am I confusing dimensions (3648 x 2736) with resolution (72 dpi vs 180 dpi) and does that mean that the FZ28 has more than twice the resolution of the FZ50?

What do these numbers mean?
