Perhaps your iPhone is the "iPhone 11 Series"? If you try to shoot in a dark place, the internal sensor will automatically measure the surrounding light and "Night mode (night view (night view))"The number of seconds (exposed seconds) required for shooting in "mode) is displayed.
In general, you have to open a shutter for a long time to take a clear photo in a dark place, but the longer you open, the more likely it is to shake and blur.It is also necessary to adjust the color so that the color looks natural so that the bright part does not become colored.Night mode is a new feature used in the iPhone 11 series to solve this problem.
If you cut the shutter with a camera application in night mode, you will analyze multiple images taken to correct the movement, destroy the blurred parts, adjust the contrast and color, and perform synthetic processing.Furthermore, the AI function mounted on the iPhone removes noise and emphasizes the fine parts to make the final photo.This series of processing allows you to take relatively clear photos in dark places without lighting.
Night mode is automatically enabled when the camera app is launched in a certain dark place, so you do not need to be aware of its existence.Whether it is valid can be determined by the appearance of the yellow button, and when the iPhone is vertical, it is displayed on the upper left of the screen, when it is horizontal, and it disappears by moving to a bright place.
Tap the yellow button to adjust the exposure time, automatically, and adjust at the maximum.However, since the maximum value is determined by the amount of light that the sensor is automatically detected, the maximum value is 3 seconds if the button is displayed as "3 seconds".
If the iPhone is attached to the tripod, it is detected in a fixed state, the night mode can be set up to 28 seconds.If you use a small tripod, the shooting target of the iPhone 11's camera should be greatly expanded.
