An in-depth knowledge of dynamic range (DR) is necessary to capture images with more details.

You can ultimately realize your creative vision by using the core technical principle of DR in photography and cinematography. The dynamic range of modern digital camera sensors is lower than that of the human eye. That clarifies why we don’t always like the photographs we take. This is due to the fact that the sky is not as washed out and the shadows are not as dark as they appear in the photographs.

DR can therefore be used to make relative comparisons between the scene as it actually is, what your camera captured, and the image you see on your screen or in the final print. In the following sections, let’s delve deeper into them.

What is Dynamic Range?

Dynamic range is the degree to which the brightest spots in your photo can differ from the darkest spots without sacrificing details – all in a single exposure. When you have a higher contrast between light and dark, you will be able to capture more accurate scenes.

More detail may often be captured in both the highlights and the shadows when the dynamic range is high. A low range could result in missing or blown-out features in the highlights or in the shadows. It means that your camera’s dynamic range is most likely limited. This issue will occasionally arise with almost all cameras.

Thus, the dynamic range is seen as the ratio between maximum light intensity, and minimum light intensity, which can be measured and portrayed by the camera.

Why Dynamic Range is important?

Imagine you’re taking pictures of a setting that features a closet that is heavily darkened and lacy white window curtains that are directly exposed to the sun. The closet appears to be dark in the first photograph; every intriguing element has been overshadowed. Well, no problem; all we need is a longer exposure period. You take a second picture while increasing exposure. The closet looks excellent, but now that the curtains are entirely white, you’ve ended up losing all of the detail in a separate area of the photograph.

This case explains the fundamental DR restriction of an image sensor. The concept of dynamic range photography should be viewed as a bracket. The tonal range of this bracket varies from white to black. A camera’s dynamic range is simply the tonal range where it can capture detail and information. Outside of this spectrum, all of it is clipped or flattened to pure white or black. The highlights of your image will become less detailed if you overexpose it. You end up losing shadow detail if you underexpose your photograph.

Understanding Light: Reflectivity and Illuminance

A thorough understanding of light and how it will affect your photos is one of the most crucial abilities to have while shooting a photograph.


Therefore, while evaluating dynamic range, precise brightness measurements are essential. Instead of measuring the reflected light, they wish to measure the illuminance or the incident light that touches the subject. In similar circumstances, photographers measure the lighting with handheld light meters before manually adjusting the exposure settings on their cameras.


Situations with significant reflectivity variation, for instance, those that feature both strong reflections and black objects, may often have a higher dynamic range than scenes with a high incident light variation. Your camera will therefore attempt to balance the hotspot areas with little reflected light when photographing scenes with high contrast. You’ll experience underexposure and overexposure problems until you instruct the camera on how to fix its exposure problems.

High Dynamic Range

Low-range cameras frequently allow shadows to become entirely dark and/or highlights to get overexposed and lost. Detail and information are much better preserved in both highlights and shadows with a higher range.

The advantage of a wider dynamic range is that the camera sensor can capture more detail in the highlights and shadows of an image. This also implies that when modifying your photograph in post-production, you have more control over it. Additionally, you can expose every part of your photograph appropriately with less reliance on artificial light.

A higher range can distinguish between cinematic shots and video-like shots when it comes to cinematography. In general, taking better pictures will result from having a wider dynamic range.

What is Single exposure High Dynamic Range?

When the entire or the majority of the scene’s tonal range can be caught in a single photograph, it can be referred to as single exposure HDR. With single-exposure HDRs, the image contains both shadows and highlights. In Single Exposure HDR, we take advantage of the sensor’s inherent Dynamic Range capability.

What is Multi exposure High Dynamic Range?

By combining several different exposures of the same subject matter, the multi-exposure HDR technique can capture HDR/WDR imagery.

Although sensors already have the potential to enable increased dynamic range, digital processing also offers the chance to produce images with a higher dynamic range. Either the host platform (a PC or embedded system) or the ISP can perform this digital processing. ISP, however, would improve the procedure.

The most popular technique for taking photos with a large dynamic range is multi-exposure HDR processing. In order to create an HDR photograph, multiple low-dynamic images of the same scene are taken at various exposures, and then those are combined.
