Hi there.

The 3 x 2 ratio, just happens to be well known to ex 35 mm Film Camera
users, and therefore there is one less thing to think about after changing
to digital.

As you say, there is no real reason why all the Camera Makers should stick
to that shape.

What really "amuses" me, ( if I owned one it would be "pissed off"), is the
little direct Printers which all seem to be 6 x 4, when most of the P & S
Cameras seem to be 12 x 9 format. These Prnters are aimed directly at P & S
users, who keep wondering why Heads or Feet get cut off from Landscape
Format shots.
