You haven't left any markings attached in the side-car of your file!
So no way to see anything from the shooting data
never mind.
However Samsung lets this data appear in general (
...>) such as ISO sensitivity, speed, aperture, possible exposure compensation, preset white balance, etc.
On the other hand, the size of the image at 100% fully confirms what I said:
1) the upper part of the image is slightly underexposed because there is not yet lightning, which appears - by observing well - only on portion of the lower part (we see it very well now in comparing the facade of what looks like a steeple on the right ... The over-ex portion is clearly predominantly bluish and covers only 1 / 5th of the image, as evidenced by ° Kelvins corresponding to the cold color temperature d 'a lightning).
2) if we now look at the second part at the bottom, there is the 1 / 5th over-ex, followed by a second underexposed area to the bottom, and which begins in a horizontal line passing below the channel of the roof, towards the upper limit of the small windows on the yellow facade (top floor).
It is as if we had the mark of a first curtain at the opening followed by the curtain mark corresponding to the closing ... And between the two, the lightning that prevailed.
I don't see it as a scanning limit of an electronic shutter, on the one hand since in this case, nothing would prevent seeing the continuation of the lightning (while it is clearly interrupted), and in the Another case we would eventually have the typical CMOS scanning trace, but we would only have a separation delimiting two zones, whereas here we have two, for three zones! So I'm tempted to stick with what I said (but that's just my feeling.)
