WebA light meter, a specific type of photometer, is used to measure the amount of light present. In photography, light meters help the photographer determine the correct shutter speed and f-number selection for the desired exposure. They are also used for cinematography, scene design, architectural lighting design, and for plant growth systems. WebPhotometry is the general term used for observing astronomical objects by measuring the light coming from them. Optical filters have an important role to play in this, by helping to define the spectrum of light that is observed. This may seem counterintuitive, since optical filters alter the observed signal, but it restricts the waveband to an ...
