In this scenario, the window is behind you (you have your back to the window), so soft light is falling onto your subject. The lighting is likely even and flat with no shadows (provided, of course, that there is no direct sunlight coming through the window). Here, the light was behin...
A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. Based on the semiconductor material used and the amount of doping, an LED will emit a coloured light at a particular spectral wavelength wh

What is a Directional Microphone? Thus, a directional microphone is a microphone which either picks up sounds only from a specific direction, or well from all angles; it depends on the directional characteristics of that microphone. Below is a list of the most common types of directional microph...
LED is a directional light source, reducing the need for reflectors and diffusers. LED emitters transfer light, not heat. LED contains no toxic mercury or glass. LEDs do not emit UV and IR radiation, which reduces eyestrain and fatigue. ...
Lux is a measure of illuminance, the total amount of light that falls on a surface Lumens is a measure of luminous flux, the total amount of light emitted in all directions. LED spotlights When to use lux vs when to use lumens
What is Sunlight? Sunlight is electromagnetic radiation, or energy, that is emitted by the Sun. It consists of visible, infrared, and ultraviolet light. Properties of Light All light, regardless of its source, behaves in a similar way. It has both wave-like and particle-like properties, whic...
Since this could end up causing more problems for drivers, the Federal Highway Administration set uniform standards in 1935for all road signs, pavement markings and traffic signals, requiring them to all use red, yellow and green light indicators. Red is the colour with the longest wavelength; ...
LED lighting is a lamp or other light that uses light-emitting diodes (LEDs) as a source of illumination. Most lighting comes from an incandescent or fluorescent light bulb. Although they are different than the traditional bulb, LED bulbs are available that can be put into traditional lamps ...
