Dynamic Range In Photography

What is Dynamic Range in Photography?

On photography websites, you’ve probably heard the term dynamic range thrown around a lot. But, in photography, what exactly is dynamic range? What exactly does dynamic range imply?

It’s a well-known phrase that many people don’t fully get. Dynamic range is defined as the difference between the maximum and minimum values. In other words, the difference between the deepest black and the brightest white. The dynamic range of a photograph is the difference between its brightest and darkest areas.

Contrast is another way to describe dynamic range. To put it another way, having a high dynamic range means that there is a lot of contrast between the dark shadows and the brighter highlights.

Unfortunately for everyone, cameras do not have the same dynamic range as our sight. There is no camera on the planet that can see as well as the human eye. Even if a camera has a great dynamic range, that doesn’t always guarantee that the tonal changes will be noticeable once the shot is printed or uploaded to the internet.

How is Dynamic Range Measured? 

The dynamic range is measured in what is known as “stops.” To better grasp, this, consider that the human eye can perceive approximately 20 stops of dynamic range in real life. This means that the darkest tones we can see with our eyes at any given time are approximately 1,000,000 times larger than the brightest tones we can see at the same time. This is why humans can see both extraordinarily brilliant and extremely dark objects at the same time.

Cameras do not have the same potency as human sight. Even the best-sophisticated cameras nowadays have a maximum dynamic range of 15 stops. That doesn’t even come close to what our eyes can see. And this is mere with the most expensive cameras.

The dynamic range of most conventional digital cameras is only about 12 stops. The problem with this is that when you take a picture on a sunny day or in bright light, your images typically appear bleached or overly bright. Your camera is attempting to decide between lights and darks, which frequently results in whitened photographs with completely black shadows. The sky will be incredibly blue in the background, but the shadows, even the smallest shadows, will be pitch black.

However, there is another difficulty with the dynamic range. Even though your camera is capable of handling 15 stops, most screens can only display 10. As a result, when you have your images professionally printed, they might occasionally seem even worse.

How to Improve Dynamic Range in Photos?

There are a few terrific techniques for increasing the dynamic range in your images to make them look immensely better. Much of it is in post-processing, but you can change your camera settings, use artificial light, or apply a particular filter.

Graduated Neutral Density Filter:

A graded neutral density filter reduces the quantity of light that enters your camera’s sensor. The filter is a unique piece of glass with a gradation from light to dark. It’s used to keep too much light from overexposing the image’s brightest parts. You’ll get bright backgrounds with properly illuminated foregrounds if you use one of these unique filters; no more black shadows.

To properly employ a neutral density filter, take a light meter reading of the foreground and background and calculate the difference in exposures. The filter must then be set to within one stop of the light difference.

After you’ve chosen your filter, place it in front of the lens, check that everything in your scene is properly exposed, and then take the photo. If anything doesn’t look quite right, simply make some little tweaks and retake the photograph.

Artificial Lighting:

Using artificial light instead of natural light is one of the best strategies to avoid taking photos with too much exposure. You can cover the darker sections of the scene with artificial light by using the camera flash or other lights in your photograph. This reduces the amount of light that your camera is attempting to catch. Instead of forcing your camera to distinguish between the dark and the light, you just fill the darkest region with your own light.

Of course, artificial light doesn’t assist much with landscape photography or anything that requires a long exposure. This is preferable for portraits and close-ups.

Exposure Settings in Your Camera:

Adjust your camera’s settings to try to compensate for poor dynamic range. Most current cameras include exposure compensation settings. Some cameras have night photography modes, bright daytime modes, and similar features. You can also experiment with a very low ISO to broaden your camera’s dynamic range and better capture the great contrast in varied scenarios.

Photo Editing:

You may need to modify your photos at times. Assuming you shoot in RAW mode, your images will have enough information to allow you to edit them appropriately to bring out the full dynamic range.

It’s actually fairly simple to improve the brightness of your photos. All you have to do is launch the highlights and shadows tool. Use the highlights menu’s sliding bar to restore the brightest sections of the image, and then use the shadows menu’s sliding bar to lessen the darkness of the shadows to bring the contrast into focus.

If you still need to make some changes to the image, you can use the brush tool to lighten or darken troublesome spots. You’ll need a fairly trustworthy editing application for this, however, you can still make modest edits with simple phone apps.

Shoot in a Different Environment:

If you don’t want to fiddle with retouching photos or utilizing artificial light, the simplest approach to boost the dynamic range of your shots is to simply wait for better weather, shoot your photos at a specified time of day when the lighting is more favorable, or simply move into the shade.

The problem with photography on a sunny day is that there is far too much contrast between the brightness of the sun and whatever is in the background. It can make a big difference to shoot on an overcast day or when the sun isn’t directly overhead.

Also, avoid pointing your camera directly at the sun. The sun will bleach the image and make even the smallest shadow too dark to see. Keep the sun behind you to properly illuminate the scene and create an appealing dynamic range that your camera can capture.

HDR Photography

HDR photography, also known as high dynamic range photography, is a unique technique for capturing images with a wide dynamic range. The problem is that it is a little difficult. To generate a quality HDR photograph, you’ll need to take anything from two to ten photos. The technique is to take many photos of the same item at varying exposures. You then use software to combine the several images to create a final image that is substantially better than any photo taken with that same camera.

A tripod is obviously required for this. You don’t want to touch your camera at all, and you don’t want even the least amount of camera wobble. Then, using different shutter speed combinations, you may create a sequence of images with variable brightness. You want to start dark and eventually brighten up. In the end, you’ll have a series of photographs that are all the same but cover the entire spectrum of light.

Once you get all your images shot, be sure that you double-check to make sure they are the same. You don’t want a bird flying in front of the camera or anything else moving that could alter the final image.

Then, using computer processing tools, combine the photographs to create a single image. Unfortunately, this software can be quite costly. Packages can cost as little as $40 and as much as $100. But if you genuinely want to take some outstanding HDR shots with amazing dynamic range, this software is vital.


So, what exactly is dynamic range? It is the distinction between the dark and light areas of your photographs. Even the best cameras have limitations when it comes to capturing darkness and brightness in the same image, making dynamic range challenging to control.

Even if you have a camera with a low dynamic range, there are ways to boost the contrast in your photos. You can experiment with HDR photography, shoot in the shade, use your own artificial light to highlight the dark regions, and edit your shots after they’ve been taken to illuminate the darkest sections for smooth tones.
