Default D200 Advice Please

Hello people, a friend of mine (quite old and not very camera experienced) has a D200. He has a problem with under exposing shots because he accidentally moves the thumb wheel.
Is there an option in the setup which would prevent this?
Thanks for any help.
Jerry

My advice to your friend would be suggesting the use of a tripod and remote shutter activator. Reason being, if he has problems with accidentally moving the thumb wheel, he also may have trouble with tremors which would introduce shake(blur) into the image.

On page 170 of the Nikon D200 Guide, there's the Change Main/Sub option which exchanges the functions of the main command dial (the one on the back) with the sub-command dial (the one on the front). Unfortunately, that would simply have the main command dial adjust the aperture instead of the shutter speed, so that won't solve his problem. There's also the Rotate Direction option which changes the rotation direction for the command dials, but that would over-expose his shots instead of underexposing them, so that's probably also not a solution.

There is another option, however, that may solve his problem. That is the Aperture Setting option which keeps the sub-command dial (or the main command dial if the Change Main/Sub option is selected) from adjusting the aperture, so that only the aperture ring on the lens can be used to adjust the aperture. This option doesn't work, however, for Nikon's type G lenses that don't have aperture rings. Also, the Change Main/Sub option exchanges the functions of both command dials for everything, so your friend may have to learn to use his D200 all over again.

If he's using M (Manual Exposure) Mode, rotating the main command dial changes the shutter speed. No other settings are affected.

If he's using any other exposure mode, rotating the main command dial still changes the shutter speed, but the camera will automatically compensate by changing the aperture. He may not get the shutter speed he thought he selected, but at least his shots will be properly exposed.

Maybe it's time for him to stop using M.

Thanks for your help everyone.
I wasn't aware that he was using Manual.
So, in any Auto or Program exposure mode, if he half presses the shutter button to get an exposure and then moves the thumbwheel it should only alter the shutter/aperture relationship but still give an accurate exposure?

In every other exposure mode, when you adjust either the aperture or the shutter speed, the camera will atomatically compensate by adjusting the other in order to keep a proper exposure.

In M (Manual) mode, you can intentionally adjust the exposure so the camera will give you an underexposed or overexposed image.

I think what's happeneding is your friend is unintentionally intentionally adjusting the exposure settings, and that can only happen in M Mode.

Thanks again.
Is there a download of the owner's manual online anywhere, so that I can swot up before I see him again?

Yes. I included a link to it in my first post:

You can find all Nikon's downloads at their Download Center.

Having looked at the manual, if I am reading it correctly, I think he may actually be in an auto mode but is pressing the exp comp button and the thumbwheel.
OR, he's got
Custom Setting b5: Easy Exposure Compensation
set to ON.
I'm starting to think he'd be better off with a camera with less convenient controls!
