Hey guys and girls...

Just sitting here whilst my computer auto rotates a recent batch of images (by exif flag or something) and it left me wonder, how does the camera know what way round I'm holding it? Its made me confused! :p

Regards, James
 
It's got a little gizmo in it that detects which way up the camera is. Imagine something likea ball bearing in a box, with electrical contacts on each side of the box. Whichever circuit is completed by the ball bearing tells the camera which side of the box is at the bottom.

What he said! It's called an accelerometer if you want to know more about it!

That's rubbish, as everyone knows.

Inside the camera is a number of very tiny pixies who paint what they see when the shutter opens. They also make a note of whether they were sitting upright or lying on their sides when they did the painting. Anyone who says different is a heretic :lol:

It's one Imp, not lots of pixies. Thanks Sir Terry.

I think you'll find they ARE Pixies, but in FF cameras (such as the D3) they are big fat buggers who were kicked out of the Crop camera department; as a result of them being bigger, they made the sensor bigger too (hence FF) but with the same number of Pixies (well the D3 compared to a D2Xs anyway) and as each Pixie has more surface area to paint onto they get more detail - which we see as better high ISO

Simple really

Ah so cameras are recorded in mega pixies not pixels. I see.
