This is the Nikon D200. I'm going to show you how to mount the camera safely to the tripod. So you need the base plate to the tripod and it screws into the mounting hole on the bottom of the camera. To do so, make sure you've got the base plate round the right way. It has arrows on the bottom that point towards where the lens is. So you want the base plate to be fitted with the arrow pointing towards the lens. This gently screws into the bottom of the camera. There's no need to force it. Just gently screws into the finger type. And that's the camera ready to go on the tripod now. So once you've got the base plate mounted on the camera, you need to make sure that the tripod is set up correctly. The first thing you need to do is make sure this locking pin is in the unlocked position, which is on the right. You know that it's unlocked because it means that you can release the patch. If that's locked, you can't move this catch properly. So the locking pin in the unlocked position. Set the camera with the base plate mounted on. Fill it into the front of the tripod and release the catch so that it locks the camera in position. That's the camera steady in position, but if you flick the locking pin down, it's completely secure. And the camera is ready to use. To set the camera off the tripod, flick the locking pin to the right, hold the camera, and disconnect the lever and the camera comes off.
