I’ve been using a digital body about 18 months and... (
You are the victim of a "mode" In user interface design, modes are considered
a (sometimes necessary) evil.
In your car, the windshield wiper knob turns on the winshield wipers because
it is wired to the wipers and the headlight knob turns on the headlights because it
is wired to the headlights. Simple.
But in an embedded system such as your digital camera, any knob or button can
control any function. They are just input devices to a computer.. So a switch
different modes of operation, or work in combination with other switches.
On a digital camera, unlike an automobile, there are very few physical buttons and
switches, becaue they are expensive and take up space. So these few are generally
"overloaded" with functions. If your car was a digital camera, it would work
"In foobar mode, to turn on the headlights, hold down Button A while pushing
Button B twice. But in barfoo mode, to turn on the headlights, push Button B
then turn Knob C clockwise. Holding down Button A while pushing Button B
twice turns on the wipers."
In other words, some very smart Japanese engineer figures out what he thinks each
control should do in each mode. He may have a degree from pristigious Tokyo
University, but in all likelihood doesn't actually own a camera (he uses his smartphone
to take pictures). And he doesn't have to remember what the camera controls do--
he' s just designing it.
Back in the 1980s, people used to complain about programming their VCRs. Little
did they know what was coming....
