I had good use of almost all of these tips last night. I photographed a 100 year old man's birthday party, along with family portraits. You can imagine how large his family was!
I had to run back and forth to get the 9 month old laughing, I had to "slap me five" after almost every shot to get the little 3 year old to keep her hands off her face. And I had to remind thirty people on a regular basis to stop "helping" me. LOL!
