I got asked to take pictures at my nephews birthday party (7 years old), more specifically portrait pictures of him and each family member. So this would be him and one adult (or one of his child cousins) per picture.
I am very unsure how to composite the picture. We will be doing it in front of a tree, and because many of the family members are quite old and the other are rather larger than the boy, I was thinking about the adult sitting on a chair and the boy standing next to it (sitting on the lap is probably not going to work out at his age anymore). But I am not really sure and can only find composition advice for single person portraits. I would appreciate some pointers as to how to composite the portraits.
If it is relevant, I got hold of a Canon EOS 500D, but my qualification to take the pictures at the party is that I have the camera :-(
