Wedding Vow Visitor

I married my lovely wife on January 12th of this year. We chose the date based on the fact that she had always wanted her grandfather to walk her down the aisle. However, her grandfather passed away before we even met each other. January 12th is his birthday. We decided that we wanted to acknowledge him being there with us in spirit at the reception, but nothing had been mentioned at the wedding. The morning of the wedding I told my wife how I knew her grandfather would be with us.

Just like all weddings, ours was full of flashbulbs. People took digital and traditional pictures, and many of the cameras were old. Hundreds of photos were taken during the wedding and reception. I am a skeptic, but I have trouble believing that this is just dust. Here's why:

1. Literally hundreds of photos were taken at the wedding and during our vows, twelve people took photos. If this were dust from the heat turning on or someone kicking the dust up, wouldn't all the photos have this in them?
2. These photos were each taken by two different people. They were sitting aisles apart. One had a traditional camera. The other had a digital camera.
3. Of the more than 400 photos that were taken of us, only these two have anything in them. If it were indeed dust, many more photos would contain dusty prints. We were there for hours, both before and after the wedding.
4. The spots show up on the photos during the exact time when my wife was saying her vows and when I was saying mine.
   

Is it not possible these are my wife's grandfather showing himself to us, letting us know he was there? I think perhaps it is.
