"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. " - Photometry filters

WebPhotometry, from Greek photo- ("light") and -metry ("measure"), is a technique used in astronomy that is concerned with measuring the flux or intensity of light radiated by astronomical objects. [1] This light is measured through a telescope using a photometer, often made using electronic devices such as a CCD photometer or a photoelectric ... WebSDSS Filters. Knowing that the color of a star is related to the wavelength of light it gives off lets you understand the meaning of the SDSS's color filters. Each filter is designed to let in light around a specific wavelength. The filters work by blocking out light at all wavelengths except those around the wavelength they are designed to see.
