A fantastic way to controllably darken an over-bright scene.
I've been experimenting with filters recently to try to improve my control of the qualities of my videos and images. One problem I frequently encounter in shooting outdoors is that I choose an ISO speed for a lighting situation, and I'm having to readjust that ISO for changing lighting. This filter cleverly layers two polarizing filters over one another in a single mount, and allows the front one to rotate. Since polarizing filters only allow light from one direction to pass through, turning the outer filter has the effect of darkening the image, since the two polarizing filters are getting further and further out of alignment, to the point that they are 90 degrees out, and no light passes at all. As can be seen in the inset scene of the video, the image can be adjusted from quite light to absolute darkness with a turn of the filter. Its a very effective and simple way of controlling lighting levels out doors without futzing with the electronics or settings, and its useful for both still and video photography.
