Using a digital camera and linearly polarizing film, we have developed a method for observing neutral point locations in the natural light field of the atmosphere. Utilizing this method, we have observed neutral points in the upwelling light field above a water surface. We report the location of these neutral points and compare them to Monte Carlo simulations.
