Its not every day that you have the opportunity to get together 4 generations (some have 5!) but if in your lifetime the opportunity is there, then what better to get a magical memory of everyone all together. For future generations and memory boxes as well as pictures for our wall right now.
A shot like this may take precious time to co-ordinate with everyone in the family, but when the little ones are in their 20's and maybe they are having their little ones they can show the future a little bit about the past.
So for a little bit of your family time this will take around 15 minutes to capture, a forever memory for a forever changing generation.
