What Is Camera Dynamic Range
You've probably heard the term Dynamic Range (DR) used a lot in photography manufactures and camera reviews, but what exactly is it, and how does it relate to your photography and camera skills?
When I get-go got into photography, the concept of dynamic range confused me for ages, and I was also embarrassed to inquire for help or acknowledge I didn't know.
That's why we created this beginner-friendly guide – soon you'll understand the primal points about dynamic range and have the conviction to apply information technology to your advantage in creating awesome images in 2022.
We've as well included half dozen helpful tips to assist you maximise the dynamic range of your current camera.
Let's swoop right in!
What is Dynamic Range in Photography?
In a nutshell, dynamic range is the departure betwixt the lightest and darkest tones in a photograph – from pure white to pure black.
DR is essential every bit every camera has a sensor that records epitome data in tones or gray shades. Some sensors can only see the detail from dark grey tones to light grey tones – but non quite pure white and blackness.
More importantly, a photographic camera's dynamic range refers to how many increments the prototype sensor can detect between pure blackness and white – plus the tones in between.
Those increments are known equally stops, f-stops, stops of light or EV (Exposure Value) – let'south refer to them as stops from here on to go along it elementary.
Stops are the unit of measurement of measurement used in photography for reading and controlling how much light a photographic camera tin see.
If each increment in the dynamic range is a unmarried terminate, and then how many increments a camera tin can read determines how many stops of dynamic range information technology can capture.
Keep in mind that a camera sensor's ability to observe a greater dynamic range depends on the quality of the image sensor.
What are the camera sensor sizes? Cheque our guide to learn all virtually them.
How We See Dynamic Range
When you lot run across a camera advertised, they commonly say how many stops of dynamic range the camera has. Just this needs to be expanded a little beyond the sales pitch.
On average, a high-quality digital camera captures between 12 and xv stops of dynamic range at the base of operations level ISO, which is typically around 100. However, perfect lighting weather must exist for measuring the chapters – no night shadows and no highlights.
If the lighting atmospheric condition increase or decrease, and then the camera'south ability to read 15 stops of dynamic range diminishes.
What's more than, if you increase the camera's ISO value, the dynamic range will drop considerably – more on that later.
While loftier-quality digital cameras can see up to fifteen stops of dynamic range, the human being centre can encounter nigh twenty stops. But as with the cameras, that's nether perfect lighting conditions.
Think most situations where you walk into a dark room. Information technology takes some time for your eyes to adjust before you can brand out the details. Your optics are adapting to the changed conditions to detect details in the darkness – your eyes are working with a lower DR.
Pop the lights on, and your dynamic range increases a lot with the scene brightening.
Why Does Dynamic Range Affair?
A sensor with greater dynamic range would allow the photographer to 'pull dorsum' lost highlight detail in the sky using editing software.
Consider a scene on a bright sunny day where y'all can make out the details in the clouds and the landscape. Information technology looks gorgeous, and you elevator your camera to capture the pretty scene.
But when you lot look at your photograph, virtually of the landscape is well lit, just some of the shadows accept lost detail, and the sky is just pure white. That'southward because our optics take a greater dynamic range than cameras.
In other words, our optics can make out the level of details in the shadows and the highlights meliorate than our cameras can.
The never-ending pursuit of camera companies is to bridge the gap in the dynamic range seen by our eyes and their cameras. Whoever cracks that lawmaking wins the prize!
That'due south why dynamic range matters in photography – then that cameras can capture close to what the human middle can run across.
Plus, the more particular pulled from shadows and highlights, the greater the upshot.
How is Dynamic Range Measured?
In some circles, measurements of dynamic range include terribly complicated and notoriously dull mathematics.
In simple terms, DR in photography is the ratio between the lightest element and the darkest – as well known equally contrast ratio.
Measured by stops (f-stops, stops of light, EV), a stop refers to a single unit of measurement of light. Each stop upward or down in the dynamic range doubles or halves the value of light required to accomplish right exposure.
Do Megapixels Matter?
No incertitude yous've heard 'photographic camera talk' discussing the number of megapixels a photographic camera has. These are the light-sensitive receptors that cover the photographic camera sensor.
A megapixel (MP) equates to one meg pixels and indicates the amount and quality of detail a camera can capture. Traditionally, the higher the megapixels, the improve the image quality.
For instance, a typical Fujifilm X-series mirrorless camera has a 26-megapixel sensor – 26 million pixels. Nonetheless, a Fujifilm GFX100S, a larger medium format camera with a larger sensor, has 102 megapixels – 102 million pixels.
Cameras with college megapixel sensors tend to have a greater dynamic range – but not ever.
Aside from the size of the photographic camera sensor and the number of megapixels, the quality of the actual individual pixels is also critical to DR. It's the individual pixel size and ability to discover light that's most important.
Fewer, larger pixels are far better for dynamic range than more, smaller pixels.
How to Maximise your Photographic camera'south Dynamic Range
Retrieve the example we talked about earlier where your middle saw more than of the landscape than the camera? What if I told y'all that several hacks could help you bridge the gap?
There are several ways to improve and maximise your photographic camera'south dynamic range. What'south more, yous tin can practice then while out in the field with your photographic camera in mitt, or later on in editing apps.
Permit'southward take a await at the most common means of improving DR in your photos and elevating your shooting experience.
Use Graduated ND Filters

Landscape photography is a genre that has a lot of problem optimising dynamic range with current sensor technology.
A mural limerick splits to roughly half the frame filled with a brilliant sky and the other one-half with darker land and shadows.
Equally we discussed earlier, digital bodies take trouble achieving a suitable balance where the sky and the land are both correctly exposed.
The easiest way to manage this is with a Graduated Neutral Density filter.
GND filters are bachelor in a range of sizes to suit almost standard lens diameters. They screw to the front end of the lens and, depending on their level of 'density', will reduce the amount of light by several stops.
Grad ND filters have the density applied to one half of the filter that transitions to a transparent section in the other one-half.
You frame your limerick with the darker density half of the filter covering the heaven. By exposing your shot for the land, you'll ensure that the whole photo is exposed correctly.
The sky will evidence its actual colour and you'll go greater definition in the clouds – without unwanted highlights.
You tin acquire more about lens filters hither, and work out how many stop ND filter y'all should buy.
Understand Your Histogram
Nigh digital cameras have a histogram that appears on the screen – it's a graphical representation of the scene's pixel density.
Getting to know your histogram is a corking way to sympathize and manage the dynamic range.
The histogram shows greater density to the left of the graph if your photo is too dark. It will also show pixel density to the right if the scene is besides intense on a sunny day or has too many highlights.
Too much pixel density at either end asks your camera to work beyond its dynamic range – and y'all'll lose highlight or shadow item.
Keeping your pixel density within the histogram's boundaries ensures you're optimising the camera's dynamic range.
Cheque out our guide to understanding the histogram here .
Expose to the Right
I know that I just said to continue the histogram pixel density from straying to the right or left besides much. If shooting with a circuitous dynamic range and y'all take to cull between likewise vivid and besides dark, opt for too brilliant.
In doing so, your histogram will show greater pixel density to the right – without it all pushing upward against the boundary.
Exposing to the correct ('ETTR') is a term used to depict this technique.
Cameras are better at dealing with an overexposed or brighter dynamic range than with a darker one. Plus, highlights are oft easier to recover in editing software.

Shoot in RAW Format
Digital cameras give yous the choice to shoot in JPEG and RAW format. JPEG files are much smaller in size equally they only incorporate the surface layer of photograph data and detail.
Mostly, JPEGs are much harder to edit and correct in editing software.
RAW files are much bigger and incorporate all the uncompressed epitome data direct from the sensor. All that extra data means that you're more than likely to recover lost details in shadows and push button back some of the highlights.
RAW files comprise all of the photographic camera'southward dynamic range, and, using editing apps, we can brand a photograph pop.
Y'all can read more most the other differences betwixt RAWs and JPEGs hither.
Proceed ISO Depression
When optimising the dynamic range of your camera, continue your ISO as low as possible. It's easier to do when shooting in bright conditions as we don't rely on ISO to expose the photograph correctly.
Increasing the ISO may brand the whole photo look brighter, simply the camera'southward range decreases in exchange. Each increase in ISO adds light but reduces the dynamic range.
Instead of increasing ISO, consider using a wider aperture or a slower shutter speed.
Learn more than about ISO here.
Create HDR Images
Creating a High Dynamic Range (HDR) photograph effectively overcomes dynamic range limitations when done right.
If you're having trouble getting your photographic camera to expose the light and dark areas of an image correctly, consider taking several photos with unlike exposures. Some cameras accept bracketing functions to automate HDR photography.
By taking several photos of the same scene with varying degrees of exposure, you lot tin afterwards blend them in editing software to course a High Dynamic Range photo.
The blending procedure results in every expanse of the image correctly exposed, thus increasing the photo's DR.
Overdoing HDR photography oft results in photos that wait incorrect and overcooked. With the right balance and practice with HDR, you'll have correct exposure and details in the shadows and highlights.
Here's a more than in-depth guide to HDR photography, as well as a review of Aurora HDR, a software tool that helps simplify the editing process.
What Camera Has the All-time Dynamic Range?
If you're searching for digital cameras with the best dynamic range, there's a lot to cull from.
All the height photographic camera brands strive to push the ceiling of dynamic range higher and higher with each generation of digital bodies.
As a result, virtually current-gen cameras from the leading brands have exceptional dynamic range averaging anywhere between 12 and 15 stops at varying ISOs.
The Nikon D850 tops the charts as the camera with the all-time Dynamic Range although several other models are close behind.
The next step for you lot is to make up one's mind what other features you're looking for in a pro-form digital camera to trim down your list of possible choices.
Hither's our pick of the currently available cameras with the best dynamic range (we've linked to the Shotkit reviews where bachelor):
- Nikon D850 – xiv.8 stops at ISO 64
- Leica Q2 – fourteen.5 stops at ISO 400
- Canon EOS R – xiv.1 stops at ISO 800.
- Leica CL – thirteen.6 stops at ISO 100.
- Canon EOS M50 – thirteen.iv stops at ISO 100.
- Olympus OM-D Eastward-M10 Mark III – 12.iii stops at ISO 800.
- Canon 5D Mark IV – thirteen.half-dozen stops at ISO 100.
- Sony α7R Four – 14.seven stops at ISO 50
- Sony a7 III – 14.seven stops at ISO 50
- Nikon Z7 – fourteen.6 stops at ISO 64
- Panasonic Lumix DC-GH5 – thirteen stops at ISO 200
