Camera Metering Modes: How to Use Metering Modes
Discover the significance of metering modes, one of the essential settings on a camera. These modes play a crucial role in how your camera measures light, directly influencing the overall appearance of your images. Mastering when and how to utilize each metering mode is vital for achieving outstanding results with your camera. Luckily, all modern digital cameras come equipped with camera metering modes, making them fundamental for obtaining the perfect exposure in your images. Elevate your photography skills by understanding and harnessing the power of these metering modes.
Exposure metering, also known as camera metering or simply "metering," is a vital pre-shooting step. Understanding the various camera metering modes empowers you to make informed decisions and choose the optimal settings for your shots. Prioritizing this aspect will lead to stunning photographs with precise exposure levels.
What is a metering mode?
In photography, the metering mode refers to the way in which a camera determines exposure. Cameras generally allow the user to select between spot, center-weighted average, or multi-zone metering modes. Technical keywords may differ as per the camera brand.
The metering mechanism involves your camera's evaluation of scene lighting to calculate the ideal shutter speed, aperture, or ISO settings. In the earlier days of photography, cameras lacked built-in light "meters" that measured light amount and intensity. Consequently, photographers relied on handheld light meters to achieve the best exposure. Given that film was the medium used, instant previews were not possible, making the reliance on these light meters essential for capturing impressive shots.
Metering modes
Today, all digital cameras come equipped with an integrated light meter that automatically measures reflected light and determines the ideal exposure settings. If you engage in shooting using semi or full-automatic modes, the metering modes will inevitably impact your photos, even if you are unaware of them. Metering modes utilize the readings they acquire to determine the appropriate settings within their control.
The main camera metering modes in photography are:
Matrix/Evaluative metering
Matrix, or evaluative, metering is the most commonly used automatic metering mode in everyday photography and may be utilized in almost all shooting situations. It takes a series of readings in zones that encompass the entire frame, as the name implies, and then determines the overall average exposure value. Because this metering considers the entire frame while determining exposure, it is useful for low-contrast scenes such as front illumination or low-contrast landscapes. It works by separating the entire frame into multiple "zones" that are then individually examined for bright and dark tones. More modern matrix or evaluative metering systems may use machine learning algorithms to figure out the scene in front of you and change the exposure accordingly.
Center-weighted metering
The center-weighted metering mode does not directly consider your focal point. It also analyzes the whole scene, but it places a strong weight on the center of the image.
Spot metering
Spot metering exclusively measures the light intensity at the focus point while disregarding the surrounding areas entirely. This mode proves beneficial in difficult lighting situations, like capturing a subject with the sun positioned behind them. This metering mode measures a very small point, basically between 1% and 5% of the entire frame, and it allows you to capture the correct details of the focus point. Normally, cameras allow you to select your spot metering point by simply changing or moving your focus point. Some cameras also allow you to choose the size of the metering spot, and then you can decide between a tiny or large spot metering point (e.g., some Sony camera models).
