How can I set up an off-camera flash with my Nikon camera for better lighting in my photos?

To set up an off-camera flash with your Nikon camera for better lighting in photos, you will need to use a compatible external flash unit and trigger it wirelessly. First, attach the flash unit to a stand or mount it off-camera. Then, set your camera to trigger the flash wirelessly by adjusting the flash settings in the camera menu. Position the off-camera flash at an angle to create desired lighting effects and take test shots to adjust the settings as needed for optimal lighting in your photos.
