Great explanation, Thank you for taking the time to reply.The AEB setting stands for Auto Exposure Bracketing which will take three of the same shot at differing exposure/brightness levels. You'll have one that's darker, one that matches what you see in the preview screen, and one that's brighter.
This can be very useful since you can pick the one that looks best later without having to worry about getting your exposure/brightness settings perfect while in the air.
That is actually one of the first prototypes of the X-Star, I guess several of them have made their way into some of the Chinese vendors stock.Is this question in reference to the X-Star 3 Cam? It is a different model from the X-Star Premium or WiFi.
