a 100 dpi 12" document ( 1,200 pixels )
.. . enlarged to
a 300 dpi 12" document ( 3,600 pixels )

PS will guess 2,400 pixels of information, the print outs will be one that is pixelated and one that is blured.

compared to

a 1200 pixel document @ 100dpi ( 12" print out )
a 1200 pixel document @ 300dpi ( 4" print out)
(only loss of detail is in print out size)

as Aprilgem says " Using paths would probably be the best method " (for increasing the size of, lets say a vector lizard *nice examples , good work *) I agree , they re-size well in PS ...
Vector images made in and edited in, vector programs, don't have pixels (hopefully), thus take up less memory.
but still ....
in PhotoShop, this vector information is in a PIXEL edditing program.

it's the amount of pixels in the image that defines the file size, not necessarily the DPI.
