I recommend turning auto-orientation off, because many graphics
applications do not recognize the encoding. What's worse, when you rotate
an encoded image in some apps, they don't change the encoding to reflect
this.
In other words, use of this feature can lead to chaos. You're never quite
sure how an image will display or print, especially when you send it to
someone else.
