Here is the Long Exposure Noise Reduction setting and what the in-camera help tells you
about it.
Shooting information display
You can bring up the shooting information display by pressing the button while in any mode.
The monitor displays the same info as the control panel on top of the camera, plus more. You
can use this display just as you would the control panel. As you change aperture, shutter speed,
etc. the information displayed will change. This display is useful for a few reasons. Everything is
larger compared to the control panel, therefore easier to see. Also, if you can't see the control
panel due to the position of the camera, you can use this display instead. Finally, if you press the
button a second time you'll be able to change the settings across the bottom of the moni-
tor. There's a lot packed into this display!
