A.1 Best light meter

 

Exposure is a factor that even the most proficient photographer or cinematographer is very careful about. In every type of situation, it is quite easy to end up with under- or over-exposed images, which can stress out any photograph or film creator. The light meter provides the solution to this issue by providing a measurement of the exposure to prevent those undesirable situations effectively. Now what makes the top rating models in the best light meter reviews stand out from the rest?

 

Features light reading suitable for your purposes

The best light meter for photography can perform light reading in one of three ways. It should be able to read the light falling on the subject, which is called incident light reading. It can also read the light reflected from the subject, or simply reflected light reading. Flash metering involves the use of additional modes or connections to obtain a reading despite the simplicity in metering ambient and constant light. Majority of light meters can handle all three types of readings, and each light measurement method has its own advantages and disadvantages.

With incident readings, where the light falling on the subject is measured, the light meter needs to be pointed toward the camera from where the subject is. Proven to be extremely accurate compared to reflected readings, this method ensures that the instrument won’t be fooled by dark or overly reflective surfaces, but can be quite challenging to use with extremely distant or fast-moving subjects.

Reflected readings are more frequently utilized nowadays especially with plenty of modern cameras already equipped with their own built-in reflected light meter. A light meter that handles reflected light readings takes the average of the varying reflected light and then measures across the entire scene so a photographer can have accurate exposure settings. The best light meter for landscape photography should come with reflected light readings, which ensures an extremely fast and convenient means to acquire initial settings despite the difficulty of obtaining a proper reading because of many differences in light or because there’s a great variety of contrast. The use of an 18 percent gray card can greatly benefit from reflected metering, since accuracy is improved thanks to the provision of a consistent surface from which light is to be measured. In addition, reflected metering also provides readings of several different subjects quickly so the shooter can better understand the dynamic range of the scene in its entirety.

A subtype of reflective metering is spot metering. This involves reading of a very narrow segment of the image area, usually varying between 1 degree and 3 degrees. The best light meter for beginners should even feature a wider 5-degree to 10-degree angle of view. With this parameter, a good light meter for beginner use will allow you to meter certain objects in a scene specifically while preventing you from getting thrown off by either bright spots or overly dark ones in an image, as for example, when you have a dark background or a backlit subject. In that situation, the subject would come out either overexposed or underexposed, respectively, if you simply opt for an averaged reading.

Flash metering utilizes additional modes or connections to get a reading because of the very short duration of a flash, which is usually more than 1/1000-second. A quality light meter with flash metering capability is equipped with a PC terminal or similar sync port to trigger the flash directly. Some models include a radio transmitter to work a strobe unit wirelessly. With dedicated flash mode, the meter is put on standby and then reads and saves the measurement of the flash of light as it gets triggered by another source.

Videographers and cinematographers need specialty meters for their work. Unlike common exposure meters, the ones that these individuals use can be a spectrometer or color meter that provides a detailed analysis of the lights used in filming. The supplied information can be as basic as color temperature to Color Rendering Index (CRI) measurements and spectrum graphs. These kinds of meters enable the comparison of two varying light sources and make them either vary or match, based on the needs or preferences of the filmmaker. They can also be used to check the quality of light because some illumination sources can be lacking in specific colors, which can adversely affect your resulting images.

 

A.2 Best light meter

 

Form factor that you prefer

Since modern technology for cameras has provided the user with an onboard through-the-lens (TTL) metering configuration for reflected light readings, this has led some professionals to question the wisdom of still going for a dedicated handheld unit. The best handheld light meter still happens to be the answer to fixing the insecurities you have on exposure. It is extremely accurate because of its ability to measure light in tenths of an f-stop. Its reliability is beyond dispute, so if you take a bad exposure reading using a handheld model, there is a greater likelihood that you messed up and not the instrument. The numerous advancements and settings available may enable you to take center-weighted, spot or average readings but this does not detract from the fact that for some situations, a handheld meter is still the best option.

A handheld meter will not be fooled by extreme contrast, unlike built-in camera meters. Neither will it be deceived by flash, snow, transillumination, side lighting and backlighting. While reflected light is also measured by a handheld meter, the device provides even more reliability with ambient light measurement. Built-in light meters are unable to take incident light or flash readings at all, so a separate unit to handle such situations is needed.

 

Light meter features you can appreciate

The best light meter for photographers has a host of features that are different from the ones that are in the best light meter for film. Light meters designed for film production feature expanded settings for frame rates (frames per second), as well as the ability to display readings in foot candles, lux and shutter angles.

Some light meters are designed both for still photography and filmmaking use. These types of products come with ambient full-featured flash modes and DTS Exposure Profiling for still photography. For filmmaking, they feature Cine or HD Cine modes for use with today’s Video Cine or High Definition digital single lens reflex camera. They even have a light-source filtration compensation mode, making them the best industrial light meter units. This is aside from an extended ISO range and light measurement capabilities.

Light meter facts you should know

 

What is the best light meter for photography

A handheld meter is the best light meter for photography. Handheld models are extremely accurate compared to built-in camera meters, as they are not easily fooled by flash, snow, transillumination, back and side lighting and extreme contrast. They provide versatility, precision and the ability to measure ambient light that falls on the subject instead of simply reading reflected light. Handheld light meters can measure in tenths of an f-stop.

A good quality handheld model has three modes of measurement: flash; reflected; incident. It can read from a 1-degree angle for effortless control over the exposure of the subject from any distance. It should also be able to fire a studio strobe if you use a flash. It should have the capability to record multiple pops from a single or more strobe units, after which it then calculates the correct exposure based on the collected light. The light meter viewfinder should display the exposure reading, which can also be viewed on the external LCD. Some models display how much flash is used in an exposure, compared to the amount of continuous light (ambient or tungsten).

What is the best light meter for cinematography

Good cinematography involves the use of creative lighting to influence the mood and tone. A good light meter for cinematography is easy to bring along during location scouting so you can take readings at that location. It should help you determine light ratios and maintain light levels to maintain continuity throughout the shots so even if you move in for a close up, the light can be flattering to the actor. It should enable you to communicate effectively with the film crew, from the gaffer to the key grip.

A good light meter for filmmaking does the math for you so you know the ratio is correct. Seasoned cinematographers recommend the use of both an incident meter and a spot meter. For an affordable option, you could settle for the spot meter in your DSLR camera in shutter priority mode but make sure your shutter is set properly and take your readings with that. Don’t expect the spot meter in your DSLR camera to be as accurate, though. Look for models that create custom profiles and that load the dynamic range of different camera systems that they also map first.

 

What the best light meter app

The Pocket Light Meter by Nuwaste studios is a free app that even does reciprocity calculations in addition to everything you can appreciate from a light meter app. Pay only $0.99 to eliminate the ads so you can have a larger exposure display. The app is pretty straightforward and is easy and quick to deploy. It displays a viewfinder plus three dials along with Hold and Save buttons. The ISO value has to be adjusted first. If you’re using the app when shooting film, this setting will depend on the film, so it is essential that you get the setting right. You let more light in with greater ISO values, making it vital that this value has been properly configured beforehand to prevent your settings from getting thrown off.

To focus on diverse areas of the frame, you only need to tap the viewfinder in the same way you would use an iPhone’s built-in camera. A red box informs you of the current portion of the image that has proper exposure, with the other value getting adjusted accordingly depending on whether you change the aperture or shutter value. Shooting wide open at f/2 requires that you adjust the aperture and obtain a reading for the shutter speed. The shutter speed needs to be set to 1s and the aperture ring on the camera also has to be adjusted with the provided reading from the app if you intend to do a second-long exposure.

The app can be frozen in its current position if you press the Hold button. The Save button saves a log to the camera roll on the scene you’re obtaining exposure for, along with the time and date, geographical information and exposure values. Providing practical settings, the app measures exposure correctly just like an actual light meter so it is usable for the zone system. You can also do spot metering with a simple tap on the screen.

 

 

Using a light meter

 

Whether you’re a photographer or cinematographer, you know how important light is in making up or composing your images. No light, no photograph, no film, right? However, too much light results in overexposure, which creates an undesirable silhouette effect, and what good would that be to your work? This is why photography and cinematography professionals invest in a light meter.

 

Is a light meter really necessary?

Light meters are virtually indispensable in photography and filmmaking. While it may be true that seasoned photographers are quite proficient at guessing the exposure values for a given scene due mainly to their knowledge and experience on the nuances of light, you’ll find that many of them still carry a light meter, or use the one in their camera. Basically, the light meter reads how much light is in a scene. In photography, this enables the perfect setting of the exposure time. In film making, the light meter helps save on costly film and processing costs. Since any light recording system only functions in a relatively narrow band while preventing either over- or underexposure of the image, a filmmaker or photographer should be able to find the proper exposure level for image recording by knowing the amount of lighting in the scene. This is where sheer talent alone may not suffice, and where a light meter may come in handy.

 

1.using a lightmeter

 

Why use a light meter in the first place?

In photography as well as in cinematography, a light meter enables you to set up your camera correctly, quickly and more effortlessly compared to simply relying on gut feel. Of course, a light meter won’t guarantee you can take fantastic photos or shoot great videos, because the success of your work really depends on your capability as a professional in your field along with a combination of other factors such as your choice of equipment, the setting, or even your mood or attitude toward your work. However, a light meter ultimately lightens the load to make your job easier when setting up your cameras.

 

In photography

Photographers need a light meter to help them figure out the exact amount of light falling on the scene so they can adjust aperture, ISO and shutter speed to capture a consistent tone. Highlights and shadows can be effectively captured along with ranges in between. The instrument allows you to find a space that provides the greatest range of tones by measuring the quantity of light hitting your sensor to enable you to determine whether you’re overexposing or underexposing the essential parts of your composition. Knowing the intensity of your studio lights can be supplemented by the measurement of background light, which a light meter can do. This becomes even more essential when you do outdoor photography, where the values can vary greatly in any given situation.

 

In cinematography

Good cinematography is much more than getting an exposure. It’s about carefully and creatively placing light to reinforce the story being told. The light meter is the tool you need to help you shape that light. It is a tool you can bring along when scouting a location so you won’t have to lug around and set up your camera. The light meter lets you quickly and easily get the information you need and make your plans accordingly. Knowing what the light levels are like and determining the tools you need are important steps in the pre-production process.

Secondly, a light meter is helpful for determining the light ratios and maintaining light levels. If you’re lighting a scene to a specific ratio and want to maintain continuity throughout the shots, you’ll need to know what each light is giving you and what the ratios are. That way, when the crew moves in for the close up, you can make the light flattering to the talent while maintaining the same ratios of light.

In addition the light meter allows you to effectively communicate with your crew. When you’re lighting a scene, it’s important that you’re able to communicate with your crew, from the gaffer to the first assistant cinematographer to the key grip. Precise and clear communication speeds up the work on set. If there’s a trouble spot, such as an overexposed portion of the frame, you will need to know how much to bring it down or how much you need to bring up the shadows in order to get a proper exposure. You could waste time by guessing what needs to be done and then have your crew make multiple changes, but with a light meter, you could just take a reading and know right away what needs to happen.

A light meter is also much more efficient to use instead of the camera to light a scene. If you’re lighting through the camera, it means you’ll have to wait for it and the talent to be ready and available, which is not the most efficient way of working. You can start working right away. You can also light more than one area at the same time and not have to wait for the camera or move it from one location to another. Besides, when you always use a light meter, your eye gets trained to different light levels and ratios, which allows you to work even faster.
