I have a fog machine as well, actually 2 of them. My normal method is to use dry ice in warm water in TWO coolers, one on each side of the model. Control the flow with large white board or black board depending on the lighting you are going for. I use 4 x 8 sheets, one on each side with the coolers on the models side of the white board. I have used a hair dryer to gently blow some of the fog from the dry ice as well but usually that is not needed. The fog machines work well if the studio is COLD to the extreme or you don't need the fog low to the floor, but in this case, Alex is laying for this series and the dry ice is SO cold that it hugs the floor pretty well. Although you CAN use a fan, I find it better to just let the fog do it's thing naturally as with a 5 pound block which I crack up with a hammer before I dump it into the coolers filled with water about 80% filled, the fog moves pretty well. One thing to keep in mind....IF you use the dry ice method, be ready to shoot as soon as you dump the dry ice into the water as the largest and best fog is the first to begin to roll out of the coolers. As time goes on, the fog lessens as the water in the coolers begins to cool off from the dry ice and freeze up. Have fun with it....Ralph
