In the world of photography, achieving accurate exposure is crucial for capturing the perfect shot. One helpful tool that can assist you in this endeavor is a camera’s spot metering mode. But how exactly do you utilize this feature to ensure accurate exposure? In this article, we will explore the ins and outs of using a camera’s spot metering mode and how it can help elevate your photography skills to new heights. So, grab your camera and get ready to uncover the secrets of achieving precise exposure with spot metering.
Understanding Metering Modes
When using a camera, understanding metering modes is crucial for achieving accurate exposure in your photographs. Metering modes determine how the camera measures and evaluates light in a scene, helping you to capture a well-balanced image. There are several metering modes available, but in this article, we will focus specifically on spot metering mode.
Evaluative Metering
Evaluative metering mode, also known as matrix or multi-zone metering, is the default setting in most cameras. This mode divides the entire frame into multiple zones and analyzes the light in each zone to calculate the exposure. It considers factors such as subject distance, skin tones, backlighting, and more. Evaluative metering is a versatile mode that works well in various situations, but it may not always provide accurate results in challenging lighting conditions.
Center-Weighted Metering
Center-weighted metering gives priority to the center area of the frame when determining exposure. This mode is particularly useful when the subject occupies the central portion of the image or when you want more emphasis on the subject’s exposure rather than the overall scene. Center-weighted metering is commonly used in portrait photography or situations where a specific area of the frame needs to be well-exposed.
Spot Metering
Spot metering is a metering mode that allows you to measure the light in a specific spot of your frame, usually around 1-5% of the total area. It provides precise exposure readings and allows you to control the exposure for a specific subject or area, regardless of the overall lighting conditions. Spot metering can be invaluable in situations where there is a significant difference in brightness between the subject and its surroundings. Let’s dive deeper into what spot metering is and how it differs from other metering modes.
What is Spot Metering?
Definition of Spot Metering
Spot metering is a metering mode that measures the light intensity in a very small area of your frame, typically less than 5% of the total frame. The camera then calculates the exposure based on the reading from that specific spot. This mode is ideal for situations where you need precise exposure control over a particular subject or area, even if the overall lighting conditions are challenging.
How it Differs from Other Metering Modes
Spot metering differs from other metering modes in terms of the area it evaluates for exposure. While evaluative and center-weighted metering consider the entire frame or its central portion, spot metering focuses on a specific spot chosen by the photographer. This gives you greater control over the exposure and allows you to capture a well-exposed subject, even in high-contrast scenes.

Advantages and Disadvantages of Spot Metering
Advantages of Spot Metering
- Precise Control: Spot metering provides precise control over the exposure of a specific subject or area, allowing you to achieve accurate exposure even in challenging lighting conditions.
- High-Contrast Scenes: Spot metering is particularly useful in high-contrast scenes, where there is a significant difference in brightness between the subject and the background. By metering the subject independently, you can avoid overexposure or underexposure caused by the stark contrast.
- Backlit Subjects: When photographing subjects with strong backlighting, such as a sunset or a window as the main light source, spot metering can help you properly expose the subject, preventing it from appearing dark and silhouetted.
- Bright or Dark Backgrounds: In situations where the background is significantly brighter or darker than the subject, spot metering allows you to prioritize the exposure on the subject, ensuring that it is properly exposed regardless of the background.
Disadvantages of Spot Metering
- Limited Area: Spot metering measures the light intensity in a small area of the frame, which can be a disadvantage when the subject occupies a larger portion of the scene. If the subject is not within the spot metering area, its exposure may be affected by the overall lighting conditions.
- Subject Knowledge: To effectively use spot metering, you need to have a good understanding of the tonal ranges in your scene and how the camera’s metering system interprets them. Without this knowledge, there is a chance of inaccurately exposing your subject.
When to Use Spot Metering
High Contrast Scenes
Spot metering is highly beneficial in high-contrast scenes where there is a significant difference in brightness between the subject and the background. By metering specifically on the subject, you can ensure that it is properly exposed, even if the background may be overexposed or underexposed.
Backlit Subjects
When photographing backlit subjects, such as a person in front of a bright window, spot metering can help you achieve accurate exposure on the subject. By measuring the light specifically on the subject’s face or body, you can avoid underexposing them and retain the details in the shadows.
Subjects with Bright or Dark Backgrounds
If your subject is in front of a bright or dark background, spot metering can help you properly expose the subject by disregarding the extreme brightness or darkness of the background. This is particularly useful when you want to capture the subject’s details without sacrificing their exposure.

Setting up Spot Metering on your Camera
Accessing the Metering Modes
To set your camera to spot metering mode, you need to access the camera’s menu or quick settings. The exact process may vary depending on the camera model, so it is recommended to refer to your camera’s manual for specific instructions.
Selecting Spot Metering
Once you have accessed the metering modes, navigate to the spot metering option and select it. Some cameras may have a dedicated button or dial for selecting the metering mode, making it quicker and easier to switch between modes.
Adjusting the Metering Point
After selecting spot metering, you can typically move the metering point to your desired location within the frame. The exact method for adjusting the metering point varies across camera models, but it usually involves using the camera’s navigation buttons or touchscreen.
Understanding the Metering Point
Size and Shape of the Metering Point
The size and shape of the metering point can vary depending on the camera model. Some cameras offer a fixed metering point, while others allow you to choose from multiple options such as a single point, a small circle, or a cross-hair. Understanding the metering point’s size and shape helps you accurately meter the light on your subject or desired area.
Locating the Metering Point
To locate the metering point in the viewfinder or LCD screen, refer to your camera’s manual. Different cameras display the metering point in various ways, such as a highlighted area, a dot, or a cross-hair. Pay attention to the metering point’s position to ensure accurate exposure readings.

Metering Techniques for Spot Metering
Spot Metering on the Subject’s Midtone
To use spot metering effectively, aim the metering point at the subject’s midtone, which is usually a neutral grey tone. This ensures that the camera’s exposure settings are based on a standard reference point, resulting in a well-exposed subject.
Spot Metering on a Specific Area
If your subject has areas of different brightness, you can use spot metering on each area individually. By metering on different areas and adjusting your exposure accordingly, you can achieve accurate exposures for each part of the subject. This technique works well for subjects with complex lighting situations, such as portraits with a mix of bright and shadowed areas.
Using Spot Metering with Exposure Lock
Exposure lock is a useful feature that allows you to lock the exposure settings while recomposing the shot. When using spot metering, you can measure the light on a specific spot, lock the exposure, and then recompose your frame without the camera adjusting the exposure. This is particularly helpful when photographing a subject against a changing background, as it ensures consistent exposure regardless of the recomposed composition.
Using Exposure Compensation with Spot Metering
Understanding the Importance of Exposure Compensation
Exposure compensation is a tool that allows you to override the camera’s automatic exposure settings. In spot metering mode, exposure compensation can be particularly useful to fine-tune the exposure based on the subject’s tonal range or the desired creative effect. It helps you avoid underexposure or overexposure caused by the camera’s interpretation of the scene’s brightness.
Applying Positive or Negative Exposure Compensation
To apply exposure compensation in spot metering mode, use the camera’s exposure compensation dial or settings. A positive compensation value (+EV) increases the exposure, making the image brighter, while a negative compensation value (-EV) decreases the exposure, resulting in a darker image. Experiment with different compensation values to achieve the desired exposure for your subject or creative intent.
Practice and Experiment
To become proficient in using spot metering, it is important to practice and experiment with different subjects and lighting conditions. Try photographing a variety of scenes, from well-lit landscapes to challenging backlighting situations. Adjust your exposure settings, metering points, and exposure compensation to see how they affect the resulting image. Analyze the results to gain a better understanding of how spot metering can be used to achieve accurate exposure in various scenarios.
Conclusion
Spot metering is a powerful tool that allows you to achieve accurate exposure in challenging lighting situations and prioritize the exposure on a specific subject or area. By understanding how spot metering differs from other metering modes, its advantages and disadvantages, and the techniques for setting it up and using it effectively, you can take full control of your camera’s exposure settings and capture beautifully exposed photographs.
