Have you ever wondered how photography enthusiasts achieve perfect exposure in their photos? Whether you’re a film or digital photographer, having the right tools is crucial to capturing stunning images. While most modern cameras come with built-in light meters, not all cameras have this feature, and commercial light meters can be expensive.
So, how can you achieve accurate exposure without breaking the bank? The answer lies in DIY electronics and the world of handmade light meters. Yes, you heard it right! You can build your own light meter, tailored to your specific needs and budget.
In this article, I’ll explore the fascinating world of handmade light meters and how they can revolutionize your photography. We’ll delve into the story of Martin Spendiff and Vanessa Bradley, two DIY enthusiasts who have designed a budget-friendly light meter called Photon. With the Photon light meter, you can achieve accurate exposure readings and unlock your creative potential.

How to Build a Handmade Light Meter Using a Foot-Candle Meter
Another DIY option for photography enthusiasts looking to build their own light meter is by repurposing a foot-candle meter. A foot-candle meter is a device commonly used to measure the amount of light striking a surface in areas such as photography, cinematography, and architecture. By modifying a foot-candle meter, you can create a cost-effective handmade light meter tailored to your needs.
To begin, you’ll need a foot-candle meter and a conversion chart provided by Sekonic, a renowned light meter manufacturer. The conversion chart allows you to replace the backplate of the foot-candle meter with a new scale indicating exposure values (EV) instead of foot-candles. Once you’ve created the new scale, you can print it out and attach it to the meter.
To ensure accurate readings, it’s essential to use an exposure calculator in conjunction with the modified light meter. The exposure calculator helps convert EV readings into the appropriate shutter and aperture combinations for your camera, ensuring optimal exposure in various lighting conditions. By using this DIY approach, you can repurpose an inexpensive foot-candle meter into a functional, handmade light meter tailored to your photography needs.
Step-by-Step Guide: Building a Handmade Light Meter Using a Foot-Candle Meter
- Obtain a foot-candle meter and access the conversion chart provided by Sekonic.
- Remove the backplate of the foot-candle meter.
- Print out the new scale indicating exposure values (EV) from the conversion chart.
- Attach the printed scale to the meter, ensuring it aligns accurately.
- Use an exposure calculator to convert EV readings into appropriate shutter and aperture combinations.
With these simple steps, you can transform a basic foot-candle meter into a handmade light meter, allowing you to achieve accurate exposure and enhance the quality of your photographs.

Considerations when Buying a Light Meter
When it comes to purchasing a light meter, there are several important factors to consider. Firstly, it’s crucial to determine the purpose of the light meter and choose a model designed specifically for the intended application, whether it’s photography, gardening, or other uses. Different light meters are tailored to different needs and may offer specific features to enhance performance.
Another key consideration is the type of display. Light meters may come with analog or digital displays. This choice often depends on personal preference and ease of use. Some photographers prefer the classic feel of an analog display, while others appreciate the convenience and accuracy of a digital readout.
Additional features should also be taken into account when buying a light meter. Spot metering is a valuable feature for photographers who need precise measurements in specific areas of the frame. Accurate flash metering capabilities can be essential for those who frequently work with artificial lighting. Additionally, consider whether the light meter comes with any useful accessories, such as a case or a calibration tool.
Portability is another important factor, particularly for photographers and filmmakers who need to move around frequently. Light meters come in various shapes and sizes, so finding a compact and lightweight option can offer convenience and ease of use.
Price is often a significant consideration when buying a light meter. Different models offer varying levels of accuracy, additional features, and build quality, which can affect the price point. It’s essential to find a balance between budget and functionality, ensuring that the chosen light meter meets the specific requirements and provides the necessary accuracy for the intended use.
Finally, the choice between incident light meters and reflective light meters should be made based on the specific needs of photography or filmmaking projects. Incident light meters measure the light falling directly onto the subject, while reflective light meters evaluate the light that bounces off the subject. Understanding the project requirements and the desired effect will help determine which type of light meter is most suitable.
By carefully considering these factors, photographers can make an informed decision when buying a light meter, allowing them to enhance their creative work and achieve accurate exposures with ease.
FAQ
What is a light meter and why is it important for photography?
A light meter is a device that measures the amount of light falling onto the subject and helps photographers achieve correct exposure. It is important for photography as it allows photographers to determine the correct camera settings for capturing well-exposed photos.
What is Photon, and who created it?
Photon is a budget-friendly handmade light meter based on the Pico platform. It was created by Martin Spendiff and Vanessa Bradley.
How does the Photon light meter work?
The Photon light meter contains a light sensor that reads the light level and calculates the camera settings required for proper exposure.
How does the Photon light meter compare to more expensive counterparts?
Testing has shown that the Photon light meter performs as well as more expensive light meters, providing accurate readings over a wide range of light levels.
How can a foot-candle meter be modified into a handmade light meter?
