Exposure offset value (EV). A value is mapped to an exposure offset. 2 = 0.3EV, 3 = 0.7EV, 4 = 1.0EV, 5 = 1.3EV, 6 = 1.7EV, 7 = 2.0EV, 8 = 2.3EV, 9 = 2.7EV, 10 = 3.0ev. The default value is 2.3ev. When captureCount is 3, the valid range for exposureOffset is [2, 10]. When captureCount is 5, the valid range for exposureOffset is [2, 5].

Auto exposure bracketing (AEB) will take captureCount pictures with each exposure offset by exposureOffset from the previous. If exposureOffest is larger than 5, captureCount can only be 3. If exposureOffset is less than or equal to 5, then captureCount can be greater than 3. For X4S, X5S and Phantom 4 Pro cameras, valid values of captureCount are 3, 5 and 7. For all other cameras, valid values are 3 and 5. The default value is 3.
