i think it depends. if u are refering to settings wise.
manual is where u can control the settings of a camera. like u can
select the aperature,shutter speed,white balance,ISO
auto means, the camera selects everything for you. u just aim the
cam.
camera wise.
manual is those film SLRs. to take a pic, u must charge a spring by
forwarding a lever.rewinding the film is also manual.
nothing is done by a computer chip, or shld i say, there is no chip
inside controlling anything except for a metering chip that tells u
whether u are underexposing the pic of overexposing.
