Upload & Sell: On
This might be an OK idea if you were always shooting the same scene and found yourself in need of an adjustment. However, if you are shooting a variety of scenes, that 1/2 stop of compensation might cause highlight clipping if you're pointing your camera at a subject with a lot of black in it. Most of the time exposure comp is a far better choice.
Also, exposing to the right isn't always the best idea. On newer cameras, I've found it best just to expose properly. When you expose to the right, you can inadvertently clip color channels and end up with some pretty funky color when you pull the exposure back down.
