I made a timelapse of the sunset with my 7 black, and some of the photos are much darker than the others. This happen several times, so the video made from the photos have slight flickering.
So i've searched for a dark photo, and compared its exif to the brighter next to it (15 sec lapse). The only difference is 2 in iso, but sometimes the iso even the same! No other differences, only the gps coordinates as the accuraccy is changing a bit.
Same ISO, same shutter time, same exposure.
Then why one is darker than the other? Nothing happened at the photo site, no lightnings or lights there.
