I am sure this is simple and I am just not seeing how to do it in metro. I take a screenshot and / or want to edit an existing photo using the pen to draw, write, circle or annotate on it. I know I can do it in OneNote but that does not save the image. As far as I can tell it saves it as a OneNote document.. I can't find a way to do it in the Photos app.. How on earth is this done?
