How to take off the bracketing feature off the Nikon d90?

I turned it on, and now I don't know how to take it off

Did the camera come with an owner's manual… Have you read it? If not, why not? Details will be there.

John John -

There are at least 2 places you can get the User Manual for your D90 free so you can read about its features and how to use them:

1- The manual that came with your camera (assuming you got one with it… )
2- The Nikon website's Support page - most mfrs.include downloadable versions of User Guides in the "support" sections of their websites.

You can also pay a $5 contribution to Ken Rockwell for that same info:

HDR can be fun, but you don't need to bracket all the time…

You might be amazed at the features in your camera and how they work if you read the guide. It also might prolong the life of your quite nice camera by telling you things not to do…

Look on page 92 of your user manual

There should be a "BKT" button on the left side of the camera right about where the flash button is as well. Make sure you press and hold down that button, and rotate the main control dial until it's off.
