The Canon EOS R5 Takes on Extreme Dynamic Range During Intense Denali National Park Sunset

Direct sun on snow delivers an extremely bright subject. Evergreen trees in the shade are an extremely dark subject. This scene provided both.

While an overhead sun is a bit brighter than a setting sun, this a very intense sunset scene. Bracketing exposures for potential HDR use is the safe way to photograph such a scene, but I was shooting handheld with the Canon RF 100-500mm F4.5-7.1 L IS USM Lens and relied on the Canon EOS R5's capabilities to capture all of the brightness levels in this scene in a single exposure.

When photographing landscape at sunrise and sunset, the red channel is usually the one to watch. The light is strongly warm-toned, and the directly lit portion of the scene will push the red channel high on the histogram.

In Canon Digital Photo Professional (DPP), this image's exposure was reduced by 1 stop, bringing the red channel in the brightest pixels to at or just below 255, with detail remaining in this channel. The foreground was then processed at a brighter setting and combined in Photoshop.

The setting sun hitting the tops of the Alaska Range and the clouds whisping over it in Denali National Park was breathtaking. Or, maybe I was just holding my breath too much while shooting furiously.
