Using a light meter is essential for nailing correct exposure and is crucial in deciding how much to over/underexpose, whether for technical or creative reasons. In this interview, our A-cam was on a 20mm wide-angle lens to include as much as possible in the surrounding background. We were forced to move the silk as far back as we could so that it wasn’t in frame. We know light falls off exponentially, so we used two 1k LED panels to achieve desired exposure. Different lights require different methods of adjusting intensity. Dimmers lower a light’s output by decreasing the electricity flowing into the unit that generates the light. Dimmers are great for incandescent or tungsten lights. However, they do become significantly warmer in color temperature the more they are dimmed. Another way to control the intensity of a light is by using nets or scrims. These are fabrics with a very fine mesh that mitigates the amount of light that passes through. They come in several different flavors: singles, doubles, triples, etc. These are great ways to adjust a light’s intensity without affecting its color. In this scene, a double net is lowering the light’s output by one full stop to match the exposure of the practical lights within the frame. Similar to scrims, neutral density gels can be fixed to lights without affecting color. This makes for a convenient and inexpensive option for light reduction when space is limited. ******************************************************************************

Bandpass filters are essential wherever it’s desirable to transmit only a specific band of light, rather than the full spectrum. Common applications include clinical chemistry instrumentation, immunoassays, fluorescence, color separation, flame photometry, elemental and laser line separation, spectral radiometry and environmental testing.

Note: In signal processing and electronics, a bandpass filter is a device that passes frequencies within a certain frequency range and blocks all other frequencies. For example, it could be used to block high-frequency sound.

A band pass filter may be as simple as a combination of a high-pass filter and a low-pass filter. A high-pass filter transmits light with a wavelength greater than a certain cutoff (point a), and a low-pass filter transmits light below another cutoff (point b).  Together, they create a filter that allows light with wavelengths greater than A but less than B, establishing a frequency range for the transmitted light.

A bandpass filter transmits a well-defined range of wavelengths of light while blocking all others. The width of the transmitted band can be as narrow as less than 1 nm or as wide as a few hundred nanometers. The wavelengths range that the filter transmits depends on the choice of substrate and coatings used, which determine the specific wavelengths of light that are isolated and transmitted. This defines whether the filter works best for ultraviolet (UV), visible (VIS), or infrared (IR) applications.

Commonly used specifications include peak transmission, center wavelength, full-width half-maximum, cut-on and cut-off wavelengths, pass band ripple, edge steepness and blocking.
