![]() ![]() ![]() The simultaneous dynamic range or steady-state dynamic range on the other hand is basically the dynamic range that can be perceived at any one time without any adaptation. However, part of that range consists of dark scenes can that only be sensed by the rods which are not sensitive to color. Over time, the human eye can actually adapt to different brightness levels in the range of about 46.5 stops. In effect, the brain continuously reads the signals from the eye, and it integrates this information into a single cohesive whole.īy looking at different areas of a scene, you can perceive a fairly large dynamic range. Instead, the brain also performs complex and powerful processing that ends up as what we consciously perceive. Unlike a camera, the eye does not simply take a snapshot of the image projected on the retina and store it in the brain for viewing. The dynamic range of the human eye is a bit more complex. The dynamic range of a scene may be any value, and it could even be larger than the dynamic range of the device with which you are trying to record the scene. Think of the projected image onto a sensor, rather than what is recorded by the sensor itself. One way to define it more precisely would be to say the dynamic range of a scene is the dynamic range of the scene projected onto a surface through an optical system. Of course, using the term “the scene” is a bit vague. The dynamic range of a scene is the ratio between the brightest and the dimmest parts of a scene. What You Should Know About Dynamic Range.
