Some of the newly-manufactured cinema cameras, like the Red Weapon, are beginning to push above 16 stops and closer to the 18-stop range. In fact, the human eye can see about 20 stops (EV) of dark/light difference, whereas the best modern digital SLR camera CMOS sensors currently on the market can see around 14-16 (such as the Nikon D810 at base ISO 32 or the Sony a7SII/ a7RII).
When facing a vivid, colorful sunset, humans can easily see both pretty colors in the clouds as well as details in the backlit shadowy foreground – a very wide dynamic range. The limited dynamic range of cameras compared to our own vision can be extremely frustrating to landscape photographers, many of whom (myself included) strive to capture a natural scene with as much fidelity to reality as possible – we want to create photographs that match what we see in our mind’s eye. This limitation is a factor of an imaging device’s “dynamic range”, which refers to the gap in luminosity between the lightest and darkest parts of an image. Have you ever noticed when photographing a sunrise or a sunset that your DSLR camera can’t capture the brightest and darkest part of the scene at the same time in one exposure? That you’re forced to choose a single exposure that’s correct for one but not the other?
