TechTip: Adjusting the black level
The key to contrast and detail
There is white in your image but the image looks flat? Though you have darken your camera completely you do not get black? Or is there too much black in the image and details disappear?
Besides gain, gamma and color saturation also the black level plays a role in image reproduction. A poor black level affects the dynamic range and therefore the image impression. Only if a camera reproduces black and white the full dynamic range is ensured.
