What are metering modes in photography?

Metering modes denote how the metering system of the camera will assess the scene and then dial in the exposure settings. There are three main metering modes on most cameras. These are Matrix metering, Spot metering, and Center-weighted metering.

What is the difference between Nikon and canon metering modes?

In partial metering mode, Canon cameras measure around 10% of the scene; Nikon cameras don’t typically have a partial metering mode. Spot and partial metering modes are handy when you’re shooting a dark subject on a bright background or vice versa. Wildlife photographers, in particular, get a lot of use out of them.

How do I know if my camera has metering mode?

Your camera’s manual will tell you if the markings in the viewfinder are related to the metering. Reduce that center circle even more and you will be using the camera's spot-metering mode. This allows the photographer to meter reflectivity from a very small portion of the scene.

What is the difference between metering mode and manual mode?

This is due to the fact that the metering mode that's set directly affects the way your camera exposes the scene automatically. On the other hand, in manual mode, you won't see any change at all.

What is metering?

Metering mode — often called camera metering or just metering — is something that almost all modern DSLRs and mirrorless cameras come equipped with. Metering describes the process of how your camera decides to assign the right shutter speed and aperture based on the amount of light the camera can pick up.

What is metering camera?

To put it simply, metering is a way for modern cameras to reflect light and determine the right exposure without using an accessory meter.

Can you use metering mode in manual mode?

Metering modes can be used in manual mode , but they’re also useful in modes like Shutter Priority or Aperture Priority because the camera will still adjust the settings based on what the meter reads. While some cameras will adjust automatically, many will have manual metering modes that require you to make these changes.

What is metering and why is it important?

Like we mentioned in our related article, What Is White Balance On A Camera, there are a lot of things that your camera does for you. This is the benefit of purchasing a high-end professional camera.

How to use metering mode on Sony camera?

So, your camera is on for Sony, and you press the fn button (function). You can then tab over to the metering icon (for right, bottom). Select it, and from there, you can choose the various metering modes.

What are the settings in manual mode?

Check out our related article, Manual Camera Settings: Photography Basics Overview, where we talk about the five significant settings in manual mode (aperture, shutter speed, ISO, white balance, and metering modes (you're currently reading this).

What is multi matrix metering?

Multi/Matrix/Evaluative metering modes evaluate the entire scene and calculates an average across its entirety to recommend a correct exposure.

When shooting in manual mode, what does metering mode give you?

When shooting in manual mode - this metering mode gives me an idea of where my exposure should be (according to the camera). Of course, this doesn't mean I always follow what the camera recommends - but at least I have a better idea.

What is center metering?

Center metering, on the other hand, meters the center of your scene and exposes that.

Can you use metering mode in camera mode?

It's not recommended to use this metering mode in automatic camera mode.

Why do you change the metering mode on a camera?

Changing the metering mode on your camera can make it easier to get a good exposure when you’re working in tricky circumstances.

What is the difference between Nikon and Canon?

In spot mode, Canon cameras measure about 2% of the total image area; Nikon cameras measure about 5%. In partial metering mode, Canon cameras measure around 10% of the scene; Nikon cameras don’t typically have a partial metering mode. Advertisement. Spot and partial metering modes are handy when you’re shooting a dark subject on a bright background ...

How does spot metering work?

Spot and partial metering work the same way. Your camera only measures the intensity of light from a small circle in the center of the scene. The only difference between this mode and center-weighted averaging is how large that circle is.

What does a light meter do?

Your camera uses a light meter to figure out the correct exposure settings for any scene. Like most “automatic” camera features, you do have some control over how it works. Let’s look at the different metering modes and when to use them.

Which is better, spot metered or evaluative metering?

In general, evaluative metering is the best mode to leave your camera in. While the shot above is slightly overexposed, it’s about as good as the spot metered one, just in the opposite direction; it’s a hell of a lot better than the center-weighted average image.

What are the different metering modes?

There are three main metering modes: Center-weighted average metering; spot and partial metering; and evaluative, pattern, or matrix metering. On modern digital cameras, you can choose between them. The process varies by manufacturer and camera, so look up your manual if you want to switch modes.

What is center weighted average metering?

Center-weighted average metering works on the assumption that the most important part of the image is probably in the center. It measures the whole scene but places extra emphasis on the light values in the middle.

Why Should You Adjust the Metering?

The camera can’t change the exposure of separate parts of the photo. This is why it needs to figure out an exposure that works for the whole picture. Many photographers encounter problems with it when taking images of high contrast subjects.

What is metering in photography?

Metering is a process in digital photography that works out what the correct exposure should be. The camera uses the so-called metering sensor, which is a device located inside the camera. It measures the brightness of the subject and adjusts the metering accordingly. Some people use a light meter to calculate the appropriate settings.

Why is it important to set the exposure according to where your focus point is?

This is a more advanced way of working out the good exposure for your camera. This is because it involves metering for the small area of your focus point.

Why does matrix metering try to boost the brightness too much?

Sometimes on matrix metering, the camera sees a black subject and thinks that it should be grey. It will try to boost the brightness too much because it is aiming for the average 18% grey.

What is matrix metering?

Matrix/Evaluative metering is the most complex and modern way of metering a scene. It collects data from across the entire frame and even gives priority to your focus point.

Why do dogs have centre weighted metering?

This results in darker, less visible background and surroundings. For this reason, centre-weighted metering can add a special atmosphere to your photos.

Where is the metering mode on a Canon camera?

This metering mode collects data from a small circular area in the metering centre of the camera. It covers about 10-15% of the entire scene and is only found in Canon cameras.

What is Metering?

To explain metering, we must first explain exposure. Exposure is the amount of light that reaches your camera. Too much light and your image will be too bright. Too little, and it’ll be too dark.

Where Do You Adjust Metering?

Unfortunately, adjusting or changing your metering mode differs from camera model to camera model, so do refer to the user manual for guidance.

What is the light meter on a camera?

How this factors into metering is that, in order to understand what the proper exposure is, we rely on a little guide on our camera called the Exposure Meter, also referred to as a Light Meter. This measures the intensity of light, and tells us if our exposure settings are too light, too dark, or just right.. The information is shown to us through a little parallel line with indications on it.

What is metering mode in photography?

This metering mode gives exposure consideration to the center of your image. It exposes for whatever is in the middle of the frame before anything on the corners of the frame. This is excellent for portrait photography in which lighting your subject well is more important than the background.

Why do you need metering mode?

In conclusion, setting the right metering mode helps you have an accurate exposure guide at your disposal. That takes the guesswork out of whether or not you set up your ISO, Shutter Speed, and Aperture settings properly! Making photo shooting easier, faster, and more enjoyable.

What does the 0 in the center of the camera mean?

Everything to the left of the ‘0’ center (into the minus sign) indicates darker exposure and everything to the right of the ‘0’ center (into the plus sign) indicates a lighter exposure. Above all of this floats an arrow that moves from side to side depending on how you’re adjusting your settings or where your camera is pointed. This arrow tells you where your exposure is on the exposure / light meter!

What is metering in a camera?

The camera features a variety of modes that are meant to help the photo taking process! One of such is metering, which helps you achieve a proper exposure.

What metering mode should I use for a scene?

I recommend you use evaluative metering as your default metering mode. Evaluative metering does the best job overall; it generally gives you a good exposure, even when the scene is complex.

What is partial metering mode?

Note that some cameras also offer a partial metering mode, which works much like spot metering but measures a larger part of the scene, around 10%.

How many metering modes are there on a digital camera?

Most digital cameras allow you to select from three metering modes:

How does spot metering differ from center weighted average metering?

So it differs from center-weighted average metering in two key respects: First, the size of the circle is smaller than that used by the center-weighted average metering. Spot metering uses a circle that covers about 2-3% of the frame. Second, areas outside the circle are not considered.

Why do we use evaluation metering?

Evaluative metering will help you expose for scenes where the entire frame matters. For instance, this landscape scene requires the whole frame to be well-exposed, from corner to corner:

What does a camera meter measure?

Every digital camera has a meter. A meter measures the amount of light reflected off a scene. So on a bright, sunny day, the meter will measure a lot of light. On a dark, cloudy evening, the meter will measure very little light. This allows the meter to determine how much light should be let in for a good exposure.

Why should a wedding scene be 18% gray?

If you’re photographing a bride in a white wedding dress, the scene should be brighter than 18% gray, because you want to portray all the white tones of the dress.

How does metering mode work?

This metering mode takes reflectivity information from the entire scene to try to achieve a balanced exposure for the entire scene. Meters are all different, but many multi-segment meters read information from five different areas that cover the majority of the scene and then produce an average reading of the segments. Some multi-segment meters evaluate the five segments, but alter the average by giving information of the center of the scene more weight—usually 60% in the center and the remaining 40% for the other regions.

What is center weighted metering mode?

This mode evaluates only the reflectivity information at the center of the scene as framed through the lens. Many cameras have markings on the viewfinder that show a large circle around the center of the viewfinder's center. Depending on the camera, this larger center circle may correspond to the area being evaluated in the center-weighted metering mode. Your camera’s manual will tell you if the markings in the viewfinder are related to the metering.

What does a camera light meter read?

There are exceptions, but most in-camera light meters read "reflected" light in a scene. The light source illuminates an object and that light is reflected toward the camera and through the lens. Speaking of "through the lens," you may have seen the acronym "TTL" in your camera's manual. Now you know what it means. TTL metering is the industry’s way of telling you that your camera's light meter is reading the brightness of a scene through the lens of the camera—not through a separately mounted meter. Some cameras do have a non-TTL metering system. We will return to the “incident” versus “reflected” light topic a bit later.

How to tell if a camera is overexposing?

Many cameras show a scale in the viewfinder and/or on the LCD top or rear screens that shows if the current aperture and shutter speed settings will over- or underexpose the image. You can use this information to make an informed decision to alter the exposure of the image from the baseline meter reading. The scale generally has hash marks that indicate stops of exposure.

What does TTL mean on a camera?

TTL metering is the industry’s way of telling you that your camera's light meter is reading the brightness of a scene through the lens of the camera— not through a separately mounted meter. Some cameras do have a non-TTL metering system.

What were the options before the light meter?

Before your camera measured exposure, you had two options: 1) carrying a handheld light meter or 2) guessing the exposure.

How to take a meter reading on a camera?

On cameras where you cannot move the spot region, you can aim your lens at the subject you wish to meter, depress the shutter half-way to take a meter reading, and then use an "auto-exposure lock" button or switch to lock-in that reading while you re-compose.

What is metering?

Metering is your camera’s best guess as to what the appropriate exposure for the scene should be depending on the metering mode selected. This is based on the amount of light that appears to be in the scene.

How does a smartphone camera estimate exposure?

Remember, smartphone camera sensors are colour blind. They see everything in black and white, and various shades of grey. Halfway between absolute black and absolute white is middle grey, which reflects 18% light. This is why it’s sometimes referred to as 18% grey.

How many metering modes are there on a camera?

In the metering section of your camera app’s manual settings, you’ll find three metering modes. Each one of them has its own way of evaluating the contents of the frame and set the ideal exposure for you.

Why do you need a meter for manual mode?

The meter will provide you with the best setting to achieve the exposure you want.

How does a camera calculate the brightness?

The frame of the camera is divided into zones and, depending on how much light is in these zones, the camera will calculate the average brightness and adjust the overall exposure accordingly.

What is 18% grey?

This is why it’s sometimes referred to as 18% grey. Digital camera meters are calibrated at 18%. In other words, when a camera comes across a scene that is below middle grey, it will regard it as underexposed and lift up the exposure.

What does a camera meter do?

By default, camera meters are set to read and analyse light levels of the entire frame. If there are many objects in the frame that are dark and bright, the camera will try to find the middle ground, although it might not be the best setting.
