While my setting is on A (aperture) on my Mode Dial, its my shutter speed, and sometimes my exposure compensation, that is changing when I move my main command dial

You have to hold down the exposure compensation button at the same time as turning the control dial.
The values appear on the control panel screen.

I found this on page 33 of the manual...
Set the mode dial to M and turn the control dial to set the value.
• To set the shutter speed: Turn the control dial.
To set the aperture value:Turn the control dial while holding down the
[+-](exposure compensation) button.

The exposure level indicator appears on the control panel screen, showing the difference (ranging from -3 EV to +3 EV) between the exposure value calculated by the currently selected aperture
and shutter speed compared to the exposure value considered optimum by the camera.

Do you mean set the aperture at f/11?

If you want the camera to set the shutter speed for proper exposure, turn the mode dial to the A position for Aperture Priority. Press the +/- button to display the shutter speed and aperture. Press cursor-up/down to change the aperture and the camera will change the shutter speed to give the proper exposure.

If you want to set the shutter speed and aperture yourself, turn the mode dial to M for Manual. Press the +/- button. Press cursor-up/down to set the shutter speed, cursor-left/right to set the aperture.

Full details are in the Shooting Mode section of the manual.

First, make sure you're in the manual exposure mode, not manual focus mode, as set by turning the mode dial to the "M" position.
In manual exposure mode, turning the main command dial should change the aperture, while turning the subcommand dial should change the shutter speed.
If the two command dials don't have the expected effect, reply to this post and we can troubleshoot further.

It depends on the lens.

If you're using a lens with an aperture ring, simply set the exposure mode to Manual or Aperture priority and change the aperture by turning the aperture ring on the lens. In Aperture priority the camera will set the shutter speed appropriately, in Manual you have to determine the appropriate shutter speed. If you want to use such a lens in Shutter priority or one of the Program modes, you must set the aperture to its smallest setting (largest f/number) and lock it.

If you're using a lens without an aperture ring then it's a bit harder. You can only use the camera in Shutter priority or one of the Program modes. You turn the command dial on the camera to change the exposure, and the aperture will change. If you want to use an exposure different than what the meter suggests, you can adjust it by using either exposure compensation or changing the ISO setting (or both).

If you need a manual, you can download one from
http://butkus.org/chinon/nikon/nikon_n6006af/nikon_n6006af.htm

The N2000 has Program, Program Hi, Aperture-priority, and Manual exposure modes, with exposure lock and exposure compensation capabilities. It can TTL auto and manual with flash. The meter is full-aperture and center-weighted.
The Program mode sets both the shutter speed and aperture for optimum exposure. You can adjust the exposure if you want to emphasize shutter speed or aperture. The Program Hi mode tries to set a higher shutter speed for action and/or long lenses.
You can download a copy of the manual here if you want to know more about this camera.

Once you're in the P mode, turning the command dial will change the shutter speed and aperture in opposite directions to maintain the same exposure (within the limits of the camera and the lens). You should see the shutter speed in the viewfinder change.

If you want absolute control of the shutter speed, change to the S mode. The command dial will then allow you to control the shutter speed, and the camera will automatically change the aperture to compensate (again, within the limits of the lens).

That depends on the selected shooting mode.

In Program AE, press the exposure compensation button and then up/down on the 4-way button to change the shutter speed/aperture combination.

In Aperture Priority AE you can control the shutter speed indirectly. Press the exposure compensation button and then up/down on the 4-way button to change the aperture, and the camera will adjust the shutter speed to suit.

In Shutter Priority AE press the exposure compensation button and then up/down on the 4-way button to change the shutter speed. The camera will adjust the aperture to suit.

In Manual press the exposure compensation button and then up/down on the 4-way button to change the shutter speed. You'll have to press left/right on the 4-way button to select the appropriate aperture.

That depends on the exposure mode. In the point&shoot modes the camera sets the exposure.

In P you can turn the command dial to change the exposure.

In S you turn the command dial to set the shutter speed, the camera changes the aperture to suit.

In A you turn the command dial to set the aperture, the camera changes the shutter speed to suit.

In M you turn the command dial to set the shutter speed, you hold down the aperture button and turn the command dial to set the aperture.


If you don't have a manual, get one from http://www.butkus.org/chinon/nikon.htm

exposure compensation can be dialed through the '+' and '-' keys in the upper right hand side of the camera body. The shutter speed should alone take care of the exposure meter if the aperture is more or less good...

ps: sometimes when we increase the shutter speed to 1/2000 th of a sec..it takes a while to reach the zero mark in the exposure bar since you need to dial more to reach an acceptable shutter speed like say 1/10th ...or 1"...

In addition to the "quirks" of the Landscape and Aperture Priority Modes (neither mode works as documented!)..... The camera also behaves differently in full Manual Mode (it changes the settings, whether you want it to or not to compensate for available light)... At lower Zoom Levels, the camera will adjust the Shutter Speed Only, to try and compensate for available light... For example: with the Camera preset to F5.6 Aperture, and 1/48 sec. shutter speed, the camera will adjust the shutter speed between a range of 1/30 to 1/291 sec, to try and "auto expose" the shot for lower or higher light levels, even though you're in manual mode. At an Aperture Setting of 2.8 and 1/48 of a second, the number of internal steps in shutter speed the camera is willing to take, increases dramatially - for example: shutter speeds up to 1/600 of a second, even though you have the shutter set to 1/48 in manual mode. The camera WILL NOT attempt to adjust the Aperture to compensate for proper exposure in available light (OR WILL IT??).... It depends on your Zoom settings! It won't if your're near to full wide angle, but IT WILL if you are using the Zoom. Once you cross some unknown zoom threshold (it doesn't have to be at full zoom), then the camera begins to change both the Aperture and Shutter speed to compensate for available light, even though you are in "Full Manual", versus Auto Exposure Mode. In Manual Mode, (as in Aperture Priority Mode), the amount of change the camera is willing to make to your settings, appears to be related to a preset number of internal steps, with the number of steps dependent on both Aperture and Zoom Settings, before it gives an EV Warning for Over or Under Exposure conditions.... The type (shutter speed only for wide angle, shutter and aperture for zoom) and amount (number of internal "steps" it takes to increase/decrease shutter speed and increase or decrease aperture), is dependent on the amount of zoom you are using for the current shot.
