What Is Flicker?
Flicker refers to the periodic change in brightness of a light source, which can be imperceptible to the human eye but noticeable in photography and videography. This phenomenon is common in artificial lighting, such as fluorescent, mercury vapor, and sodium vapor lights, which are often used in indoor and outdoor environments. Flicker can cause uneven exposure, color casts, and banding in images, leading to a decrease in overall image quality.
Causes Of Flicker
The primary cause of flicker is the alternating current (AC) used to power artificial lighting. AC supplies electricity in a cyclical manner, with the voltage and current changing direction many times per second. This cyclical change can cause the light output to fluctuate, resulting in flicker. The frequency of flicker varies depending on the type of lighting and the electrical supply system used. For example, in the United States, the standard frequency is 60 Hz, while in Europe, it is 50 Hz.
Types of Flicker
There are two main types of flicker: visible and invisible. Visible flicker is noticeable to the human eye and can cause discomfort and fatigue. Invisible flicker, on the other hand, is not perceptible to the human eye but can still affect photography and videography. The Nikon D780’s flicker reduction feature is designed to detect and adjust for invisible flicker, which is the type that affects image quality.
How Flicker Affects Photography
Flicker can have a significant impact on photography, particularly when shooting under artificial lighting. The periodic change in brightness can cause:
- Uneven exposure: Flicker can result in overexposed or underexposed areas in an image, leading to a loss of detail and contrast.
- Color casts: Flicker can introduce unwanted color casts, such as green or yellow, which can affect the overall color balance of an image.
