Double tap the AE slider to reset the AE value back to 0. Note: The AE value does not reset back to 0 when auto mode is initiated as it is already in auto mode. The default value is 0, which means that no changed were made to ISO or shutter speed. The camera will automatically and continuously adjusts ISO and shutter speed to achieve the selected exposure value. Note: While in auto mode, the exposure (AE) value can be set between -8 and 8+. Alternatively, double tap the camera view to reset all parameters back to auto. The exposure button will change to a yellow AE, indicating it is in auto mode. To reset exposure back to auto mode, press the AE-L button. When either shutter speed or ISO are manually adjusted, the exposure button changes from a yellow AE to a white AE-L, indicating that exposure is locked and no longer in auto mode. Note: While shutter speed and ISO can be manually adjusted on iPhone, the aperture is fixed.

Aperture controls the amount of light allowed to reach the sensor. Aperture: refers to the diameter of the opening of the camera lens.The higher the ISO the more noise is introduced into the shot. ISO: determines how sensitive the camera sensor is to light.However, longer exposure times may result in what is referred to camera shake or blurry photos if the camera is not held perfectly still. The slower the shutter speed, the more time light is allowed in to be captured by the camera sensor. Shutter Speed: controls the duration of exposure or in other words how long the shutter remains open.Exposure has three components which are commonly referred to as the exposure triangle.
