This is a series shot at 10 second intervals, and played back at 20 frames per second, its is a thousand frames over  almost 3 hours…

The lens flares are because I did not have the right filter with me, actually my 72mm Circular Polarizer has  big crack in it…

I went to the Delaware State Fair on Friday, and i had my Nikon D5000 with me, shot a lot of pictures or so I thought, because today I upload the pictures to my computer, and there is at least an hour of pictures missing. I know I took them, I have witnesses, and every-time I hit the button I could hear and see the shutter go. I wasn’t using the screen, and I was getting glare off of it so I had it turned around, so I don’t really know if the pictures were actually ever there.  It problem occurred shortly after I mentioned to my wife that the camera and lens felt a bit warm, and I started hanging out in the shade, and I thought that if there was an overheat problem the camera would shut itself off, so I felt I was good to go. The weather was sunny and 82, so the temperature wasn’t overly hot (and well within the D5000′s specs of 102), but it was sunny, and we were on concrete, so there was not a lot of relief from the heat or sun.

While I was searching for the a possible cause to the problem, I found several references that mentioned that the camera would shutoff the sensor if it overheated and you were shooting video in live view, but not reference to shooting stills. I honestly feel that this may be a related issue.

So a word of warning, if you are out on a sunny day with your D5000, and it feels warm, check and see if it is actually recording the data.

If you have experienced this particular problem shooting stills, please let me know….
