A larger From Day to Nightvalue will result in a switching to Night mode in lighter conditions, a lower valuerequires darker conditions to switch.Back to Day also provides a range (+2-+12) which adjusts the sensitivity of theswitch from night to day. This value relates to the From Day to Night; the switchto day mode is based on the From Day to Night + Back to Day values.NOTE: Auto Mode (AE) doesn’t differentiate between IR light and visible light.Subsequently, IR light can cause the IR-Cut filter to switch back to Day mode.While in night mode, if an object is close the image will appear bright from the IRlight and result in the Luminance Metering to register a high value which canswitch the camera back to Day mode. This is due to Auto Mode (AE) using imagebrightness.So, the camera shouldn’t use this setting in environments where objects are closecreating a “bright” image. Alternatively, set the Back to Day to a high value tocounteract this behavior.25
