Family pictures are complete when the entire family is there in the picture right?
Go to any tourist place or some little family gathering at a restaurant - you will surely find a family excited about getting a family picture done. You will always find a single member clicking who would remain out of the frame.
According to me a very basic act of kindness we all photographers can offer is to extend our help in creating that one magical moment for the family - friendly offer your help to click that picture. It will add a huge amount of happiness to the bunch of people and I'm sure you definitely are getting loads of blessings from the elders :) A simple act that can make their gathering memorable.
How many of you have already extended just gesture to families or bunch of friends group?
