Regardless of setting, the shutter speed seems to be 1 second

Hello. I just discovered this today. Regardless of the setting (M,A,S,P) the shutter speed seems to be 1 sec. The lens will focus. When I hold the shutter release, there's a moment before the shutter fires. I have turned the camera off. I have removed the battery. I have used the two-button reset. No difference. I'm open all suggestions to fix this problem.

Sounds like you "Exposure Delay Mode" turned ON. When turned On, when you press the shutter, there's a (2sec) delay before the shutter actually fires. The timing is variable and is set as one of the options in "Exposure Delay Mode" menu setting.

The menu option should be somewhere in the "D" section of the "Custom Setting Menu" under "Shooting/display"...

It's been awhile since I used the D90, so I don't remember the exact menu number it under.

I just looked it up. Look at menu option D10

Guidelines to adding a photo to your post.

1. Resize photo to 1000px on the long side.
2. Resolution set to 72ppi (Pixels Per Inch)

These guidelines will be good for viewing on a computer but will not be good for printing. This will help safeguard your copyright.

The two button reset only resets the shooting menu (not all settings) so there must be some other setting that needs to be fixed. Let us know how Fred's suggestion turns out.

Thanks for your reply. Fred's solution was right on the money. All's well now.

Welcome aboard. Enjoy the ride.
We look forward to seeing more posts and samples of your work.

Thanks for the welcome, Brent.
