arrr okok..
ur screen is at 72dpi. so 7200 pixels will take 100 inches of
screen space.. obviously no (sane) person would have that much
screen space..
print however is different. the usual offset print (considered low
quality) that u see in those free magazines (like IS and Juice) is
printed at about 150-170 dpi.
inkjet printers CLAIM they can do 1200dpi... i dunno how the
technology really works but as u would appreciate the higher the
dpi, the sharper the picture, PROVIDED the source is sharp.
so if u are printing at say 720dpi, a 7200 pixel long image will
come out at only 10" long, a far cry from the 100" on screen.
and oh.. printing at 72 dpi will just induce blood vomitting..
