What can I do to fix the focusing problems I'm having with my Nikon D80?

Whenever I use my nikon handheld remote, I have major problems getting my Nikon to focus (using autormatic focus) on me when doing self-portraits. Sometimes I'm somewhat in focus, but my face is soft and not completely sharp and in focus. Any tips in terms of what focus settings I should be using?

You should put something in the place were you face will be and focus on it using manual focus. Leave it set to MF, sit down and hit the button on your remote. Or have someone else take the picture.

I don't use a Nikon, so I can only answer from a Canon viewpoint.

When I do a self portrait using auto focus, I have to set the camera for single shot, the lens on auto focus, then close the viewfinder door. Once in place, I use the remote to take the shot. Some of the Canons don't have the viewfinder door, but have an eyepiece cover that is normally kept on the neck strap for that purpose.

When I use manual focusing… I setup the tripod and camera, then take the camera off of the tripod (using the Quick release). I then go to where I will be and focus on the head on the tripod. Once it is focused, I put the camera back on the tripod and take the shots.
