Default Camera Resolution reported in Adobe Bridge

Ignore the bogus resolution displays.

I realize that Windows computer monitors display at 72
dpi.


I've got a monitor that displays at 122 ppi. Most current
displays have more than 72 ppi.

You raise an interesting point that relates to my OP. I had thought that
ppi was a digital camera "thing" and dpi was a (inkjet?) printer "thing".

A pixel is a point of (RGB) color while a dot (in the dpi) are drops of
cyan/magenta/yellow ink that collectively (with K-black) make a pixel. That
said, it would take more CMYK dpi dots to make a ppi.

ppi is not just cameras.

A pixel is a point of (RGB) color


a pixel is a spatial element of an image, not necessarily rgb. it can
be monochrome, cmyk, hexachrome or something else.

while a dot (in the dpi) are drops of
cyan/magenta/yellow ink that collectively (with K-black) make a pixel. That
said, it would take more CMYK dpi dots to make a ppi.


yep, or whatever inks are used (i.e., hexachrome).
