Simply thinking about it will clearly give you the answer. You would be simultaneously cutting down the ambient light AND the light from the flash. Nothing gained. Just so you know, ND filters are graded in 1 stop increments. .3 = one stop, .6 = two stops, .9 = three stops, 1.2 = four stops, etc... :) Jim
