Most of you all know my story, I just take pics of my kids, I have a nikon d3100 with 18-55. My question is though, I want to take pics of family members over Thanksgiving since we all are going to be in one place. I want to take one of my husbands parents and the 4 boys, parents and the 11 grandchildren. Could you all give me any tips in taking these group pics. I have read it is always good to put a group in a circle. I was thinking of taking ones outside by a windmill, we live in the country and was thinking 200 shutter speed, f10 on a tripod. I am thinking of buying a new lens, any suggestions on one I can use for my kids and taking group pics. I would appreciate any advice.
