I have suddenly faced a frustrating problem with Nikon d5500. That is, while taking photos on automode, and with flash on the photos have dark band on the upper third of every photos. I would like to mention only when the flash is turned on and the problem persists irrespective of whichever mode I use auto mode or program mode with flash on. With no flash everything is fine. The shutter speed is 1/60-1/200 usually in automode when i have observed the band, never outside that range. I have also tried resetting factory settings, turning on off , fomatting the memory card BUT to no avail. I can understand this problem in Manual mode but whats the solution if the problem is in AUTO mode. Plesase get me out of this.
