When you come home with a file where the sky is blown out and the shadows are empty, the real culprit is usually dynamic range. Understanding how much brightness your camera can actually record is what lets you keep a bird sitting in both sun and shade looking believable.
Coming to you from Mario Kilian Photography, this insightful video walks through dynamic range in clear, real-world terms instead of abstract theory. Kilian starts by defining dynamic range as the number of “steps” between deep shadow and bright highlight that your sensor can separate before detail disappears. Using a modern mirrorless body like the Nikon Z7, he explains how 13 to 14 stops at base ISO give you far more flexibility than older cameras that topped out around 10 or 11 stops. You see what happens if the camera had only 2, 4, 8, and finally 14 stops, all applied to the same landscape, so you can feel how extra stops translate to smoother tonal transitions. The comparison to the human eye, which adapts through pupil changes and brain processing, makes it very clear why a scene that looks balanced in person can still clip highlights or crush shadows on the sensor.
Kilian then connects that theory directly to typical wildlife situations where contrast gets brutal very quickly. Think of a bird half in sunlight and half in shade, with water reflections and a bright sky behind it, and you are already beyond what many cameras can handle in a single exposure. The video explains how raising ISO quietly eats into your usable dynamic range, so that the 14 stops you enjoy at ISO 100 can drop to something closer to 7 or 8 stops at ISO 6,400 as noise fills the shadows. You get a simple explanation of why the histogram hitting the right edge means highlight detail is gone, not just hidden, and why backing off slightly can save a shot. When Kilian compares JPEG’s 256 tonal levels to a typical raw file with over 16,000 levels, it becomes obvious why shooting raw gives you more room to adjust exposure without the image falling apart.
From there, the video shifts into practical choices instead of pure specs. Kilian lays out when to expose to protect highlights in hard light by nudging exposure down so important bright areas do not clip, and when to expose to the right in soft light to keep shadows as clean as possible. You hear when it makes sense to drop ISO using a tripod or slower shutter, and when freezing motion matters more than squeezing out an extra stop of dynamic range. He touches on simple field tactics like recomposing a little to tuck your subject into open shade or using a tree or cloud to reduce contrast instead of relying only on sliders later. Exposure bracketing and HDR get framed as tools that can work even in wildlife scenarios when the subject holds still, rather than as tricks reserved only for landscapes.
What stands out is how much emphasis Kilian puts on deciding what to sacrifice on purpose rather than chasing a “perfect” histogram. You are encouraged to protect the subject first, even if that means letting the sky clip or letting deep shadows fall to near black when the scene simply exceeds what the sensor can record. The idea of knowing your limits by checking dynamic range tests on sites like Photons to Photos gives you a clear way to understand where your camera starts to struggle instead of guessing in the field. Kilian also reminds you that many favorite wildlife images have blown highlights or heavy shadows baked in, and that contrast itself can carry emotion when handled with intent. The technical pieces are there to support that judgment, not to replace it. Check out the video above for the full rundown from Kilian.

I have tried the , Photons to Photos site. Seems they typically show the dynamic range about 2 stops lower than generally reported from other sites or accepted specs. But far beyond my area of knowledge to explain further. Still works well enought if you are comparing one camera to another.
The picture accompanying this article doesn't instill confidence that the content creator knows what qualifies as good or bad. It has that fake HDR look. The article and video are a great discussion about dynamic range for first time camera users though.
