Dynamic range refers to the range of which a camera can successfully capture the lightest and darkest areas of an image without losing detail. Once this range is exceeded, the highlights will wash out to white and the darks will turn to black blobs. So the higher the dynamic range, the better!
A higher ISO will decrease the total dynamic range of the image. And, in many cases (like astrophotography), a higher ISO will actually decrease the visible noise.
Put simply, dynamic range is the range of brightness your camera sensor is capable of recording. The higher the dynamic range, the more details will be retained in the shadows and highlights. If you want to recover the blown out highlights, good dynamic range allows you to bring back a lot of details.
The Dynamic Range is defined as the maximum possible signal level divided by the noise level, when there is no light entering the spectrometer. The Dynamic Range is then calculated as 2n-1 divided by the dark noise.
Dynamic range is measured in stops, where each stop equals double or half the amount of light. Increasing exposure by one stop means doubling the light. If you were shooting at shutter speed 1/100, one stop brighter would be 1/50, while one stop darker would be 1/200.
How To Extend The Dynamic Range
- Shoot Raw. Because Raw files give us only the pure data from the sensor, we are getting the full dynamic range capabilities from that sensor.
- Shoot Low ISO.
- Shoot HDR.
- Learn Your Histogram.
- Shoot To The Right.
- Use A Graduated Filter.
Dynamic Range of a Receiver= value of maximum signal power, in which the receiver is not overloaded. = value of minimum signal power, in which the receiver still issues an output signal. Thus the receiver needs a dynamic range of 78.5 dB.
Obviously, for the “best” experience, you should leave DRC set to “Off”, but for practical reasons (like late-night viewing, adjacent neighbors) you may want to turn it on. In theory, the DRC will make your loud scenes (commercials) less loud while making soft dialog louder.
That's where HDR video comes in. It removes the limitations presented by older video signals and provides information about brightness and color across a much wider range. HDR-capable displays can read that information and show an image built from a wider gamut of color and brightness.
A good lens does not increase dynamic range but a bad one does reduce dynamic range (e.g.: internal flare , Spherical aberration and etc) in certain situations.

The Samsung Galaxy Note 10+ packs a host of impressive specs, and produces images with great colour and dynamic range. It also features live focus video, so you can change the amount of blur in the background as you film. If you want the ultimate flagship smartphone the Galaxy Note 10+ is the phone for you.
The human eye can perceive about 20 stops of dynamic range in ideal circumstances. The best modern cameras like the Nikon D810 can achieve just under 15 stops of dynamic range in any one photo. Most digital cameras get somewhere between 12 and 14 while film negatives can get up to about 13.
Canon EOS 90D: Image QualitySensitivity extends up to ISO 25,600 for hand-held shooting in dark conditions, while a wide dynamic range allows detail to be retained in bright highlights and dark shadows.
The better the dynamic range of the camera, the more an exposure can be pushed without significantly increasing noise.
The Nikon and Sony both continue to offer around a one-stop advantage over the Canon for dynamic range between ISO 1600 and over the Canon 5DS's top sensitivity of ISO 12,800. So good dynamic range above or around 10 EV is possible on the Sony and Nikon up to ISO 3200, compared to ISO 1600 for the Canon.
The EOS 5D Mark IV with Canon Log records 4K and Full HD video files that feature an increased dynamic range of up to approx.800% or 12 stops (at ISO 400 or above), ideal for extensive post-production processing.
By some estimates, the human eye can distinguish up to 24 f-stops of dynamic range. Higher end DSLRs such as the Nikon D800 by comparison, can capture up to a theoretical max of 14.4 f-stops of dynamic range.
INFLUENCE OF LIGHT: ILLUMINANCE & REFLECTIVITYScenes with high variation in reflectivity, such as those containing black objects in addition to strong reflections, may actually have a greater dynamic range than scenes with large incident light variation.
In short, the greater the dynamic range the greater the difference between quiet and loud. This does not necessarily mean a recording of a dance track with a DNR of 4dB is a worse recording than a symphonic recording of a classical piece at 14dB, it just means the music is different.
Term: Dynamic rangeDynamic range is another way of stating the maximum signal-to-noise ratio. To use sound as the example, this is the ratio of the loudest (undistorted) signal to that of the quietest (discernible) signal in a system as expressed in decibels (dB).
