SLOW RESPONSE
The slow response function allows you to lengthen the automatic exposure response speed
from 1 up to 32 times. For example, with the normal setting (about 1 second), if the
headlights of a car are caught by the camera, the camera automatically adjusts the exposure
so that it can shoot a high-intensity subject (in this case, the headlights). As a result, images
around the headlights, that is, the rest of the subject, except the headlights, becomes
relatively dark, and poorly distinguished. However, using the slow response function can still
easily distinguish the portions of the image surrounding the headlights.
DN THRESHOLD 5, … 18 (default),…, 28
Adjusts the level of light at which the camera automatically switches
out of night mode (B/W) operation.
