My Nikon D3300 was working perfectly then today I started using it and it will only produce black photos on any mode. Yes, the lens cap is off. I've tried restoring the settings, restarting, removing and reinserting SD, doing a power interrupt start up and nothing works. The photos come up as black on my display, on the live view setting and on my laptop once downloaded. From what I can see the shutter is functioning normally and the mirror is not broken so I really have no idea what could suddenly be causing this. I'm in Marrakech and losing out on some great moments so any suggestions would be much appreciated. enter image description here

  • What exposure mode are you in? (Program, Aperture, Shutter, Manual)? Are you using Auto ISO? Has it been dropped, exposed to water, or any sort of extreme situation? What lens is on your camera?

  • @scotbb thanks for the help. I've tried it in all modes, Manual, Auto, Shutter etc. Both auto ISO and manually setting the ISO. It hasn't moved since the last time I used it, when it was working perfectly. I'm using a Sigma DC 18 -200 mm Lens Oct 28 '17 at 16:50
  • Are the photos pure black, or is it possible they're just really really dark?

What happens in manual mode, ISO 800, wide open lens, 1 second exposure time in an outdoors setting? My thought is that an exaggerated example may be useful for ruling out a few possibilities.


The same thing happened to me today during a meeting at a short circuit raceway (as you could imagine, there's a lot of dust being flung about). I switched over to my backup, a rather elderly D40, and carried on but when I got home, I ran through a number of things that could have been at fault. First of all I checked to see that the shutter was working normally, which it was. I then went into the menu and selected the "Clean Image Sensor" option. On the first attempt, I noticed that I was getting something, so I ran it again and all now appears to be working again.

I still intend to keep the D40 around as it's a nice camera but this appears to have sorted my D3100 for now.
