[QUOTE="dr_eyehead, post: 316185, member: 25249"] Normal light is randomly polarised though isn't it? So if you use two polarised filters, each with an even density then the density should not change as you adjust them relative to each other, all you are doing is restricting the polarity. Is there an issue with the angle at which light is coming in through the filter not varying linearly with the strength of the filter maybe? I googled and someone was complaining about dark spots in the corners. [/QUOTE]
