People love photos and love to take photos! One of the photos I like to take is other people taking pictures. It could be a selfie or someone with a high end DSLR. Sometimes the bride (attempts) to restrict obtrusive photography during the ceremony but it’s always fair game everywhere else! I love it. The more cameras, the better. I can’t be everywhere all at once. So I welcome others taking pictures to catch that sweet moment that I might miss. I carry an extra backup camera in case I see a child interested in what I’m doing. I set the camera on automatic and give it to the kiddo. They often get some great shots!
