I have pretty much eliminated foging by this method.
I install the camera in the housing in my room but do not close the door. I crank up the AC to full to making sure the compressor is on and then hold the housing and camea in front of the AC outlet, letting the dry air blow into the housing for a couple of minutes. This drys out any moisture that may be in/on the housing and camera and floods (maybe not the best word to use
) the housing with dry air. I close the housing while in the air stream. Once out of my room, I keep the housing as cool as possible, always covered with a thick towel or in the rinse tank. I carry with me a large baggie- a white garbage bag will do- with a towel soaked in fresh water to the dive site. The camera and housing is wrapped in the towel and placed inside the bag for transport home. This prevents salt water from drying on the seals before I can get back to my room for a proper soak and rinse. A little extra work but my housing never fogs and is still going strong after a lot of dives.
