The location tends to plan the activity itself. Do what you always do as a family and then everyone will have a good time and great photos will be the outcome. This gives the children a chance to get used to me and the camera.
I will just hang out with you and if you have fun with your family, the photos will reflect that. The posed shots are not painful, they are natural photos of you all enjoying the moment. I tend to work them into the overall fun of the outing or home activity.
