warming and cooling, graduated, and specialty filters, but editing software has primarily made most of these photography filters superfluous. I would argue that a photographer needs no more than an ND filter and a polarising filter these days, and here we will discuss...
An electro-optical modulator that attenuates and controls the beam when speed is essential, for example in photostimulation experiments. This is faster and more precise than using the half-wave plate/polarising beam splitter units or Neutral Density filter wheels. ...
(also known as an ND filter) can help to diminish increased light on the water. An ND filter reduces the intensity of light while still preserving colour — an essential feature for any photographer who shoots outdoors. A polarising filter or circular polariser, works in a similar way, but ...
