Dynamic range in photography is an important characteristic of a camera that refers to the range of brightness that the camera can capture. It is the difference between the darkest and the brightest parts of an image that the camera can capture.
A camera with a high dynamic range can capture more detail in both the shadows and highlights of an image, resulting in a more well-rounded and accurate representation of the scene in the photograph.
It’s one of the biggest challenges in photography for our modern day cameras, as we try and help our cameras to match the human eye, which can see a dynamic range of up to 20 stops.

The dynamic range of a camera is measured in stops, with each stop representing a doubling or halving of the amount of light. For example, a camera with a dynamic range of 12 stops can capture a scene that is 12 stops brighter than the darkest part of the image.
The dynamic range of a camera is determined by a combination of factors, including the sensor, the lens, and the image processing algorithm used. The sensor is the most important factor, as it is the part of the camera that directly captures the light.
The larger the sensor, the more light it can collect, and the higher the dynamic range. Cameras such as the Fujifilm GFX100s has an incredible dynamic range as the medium format sensor is seven times larger than a full frame sensor.
The lens also plays a role in determining the dynamic range of a camera. A lens with a wide aperture, such as f/1.4 or f/2.8, allows more light to enter the camera, increasing the dynamic range.
Additionally, lenses with low levels of distortion and chromatic aberration will also help to increase the dynamic range of the camera.

Finally, the image processing algorithm used by the camera also affects the dynamic range of the photograph. Modern cameras use algorithms that are designed to extract as much detail as possible from the sensor, including detail in the highlights and shadows.
These algorithms use techniques such as tone mapping and noise reduction to increase the dynamic range of the camera. The algorithms used by smartphones play an enormous role in enabling them to outperform many high end cameras for dynamic range.
Modern Fujifilm cameras have three dynamic range settings: 100%, 200%, and 400%. The 100% setting is the camera’s standard setting and is suitable for most shooting scenarios and will give you the best quality image – and is my recommended setting.

The 200% setting extends the camera’s dynamic range even further, allowing for more detail in highlights and shadows. The 400% setting is intended for extremely challenging lighting conditions and can be used to capture even more detail in high-contrast scenes.
When using the dynamic range setting, it’s important to note that the camera’s ISO sensitivity will be automatically adjusted to maintain the correct exposure.
Additionally, the dynamic range setting will have an effect on the overall image quality and may result in a slight loss of sharpness and an increase in noise in the final image.
Using the dynamic range setting on Fujifilm cameras can greatly improve the overall quality of your photographs.
For example, photographers can easily expose a shot correctly for a bright sky while still preserving the detail of dark shadows and faces in the foreground. It’s a versatile and powerful tool that can help you capture incredible images in any lighting conditions.
Another way of overcoming a cameras dynamic range limitations is to use filters such as ND filters. They will allow the camera to expose for both areas of the scene (sky and ground) and prevent the photograph being overexposed in the sky, or underexposed on the ground.
The dynamic range of your camera is a crucial aspect of modern technology, and part of the reason modern cameras are so expensive, as it allows for the capture of a wide range of tonal values in a single image.
The ability to capture images with high dynamic range has greatly improved in recent years, due to advancements in sensor technology and image processing algorithms.
As a result, modern cameras are able to produce images that are more detailed, with greater contrast and color accuracy. While some cameras still have a higher dynamic range than others, it is an important factor to consider when choosing a camera for photography.
Whether you are a professional photographer or an amateur, the ability to capture images with a wide range of tonal values will greatly enhance your final results.
