photo dpi ?? (dots per inch)

[christine2000]

i've checked both explorer and mozilla, and there's only 'general' under properties, and no dpi can be found;p
anyway, do you think a picture with 180*180 dpi is 300 dpi at least?;p

I'll make a screenshot..

Also the manual:
Nero Photo Snap

page 30


edit:

step 1, properties:



step 2, second tab in the properties menu:

they are called horizontal and vertical resolution

dpi or "dots per inches" is the "information density" of a displayed or printed image, computer screens typically display 72 dots (or in this case, pixels) per inch, the norm for good quality prints is 300 dpi.

It's not an intrinsic value of an image that a program can give you, since it's a ratio between what size your image is, and what dimensions it will be displayed/printed out across.

A 1280*1024 pixels image will fill the average 17 inches screen at 72 dpi, but printed at 300 dpi it will fill a measly 4,3 by 3,2 inches (roughly).
A picture that must be printed at 300 dpi and fill a A4 format (roughly equivalent to US Letter, if I'm calling that properly), would need to be about 2500*3500 (portrait orientation) or 3500*2500 (landscape) pixels large.
