Intensity of lightsmeaning

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. ******************************************************************************

Getting a camera for my stream this weekend and want to make sure lighting is good 👍🏻 anyone have suggestions for a quality ring light that won’t be insanely expensive? 😂
