Those few hours will be remembered by one’s children and grandchildren in those photographs that they’ll cherish for generations.
In some families, it doesn’t happen very often that family from around the country, world, community comes together in their finest clothing to celebrate a day when photographs can be taken.
NonJews may be able to take photos whenever. They can have family reunions and before anyone eats and looks tired, they can snap photographs. OTOH, for frum Jews, many of these family reunions happen on Yom Tovim and Shabbat.
Recently I went to a family member’s home and saw pictures of my grandparents that I have never seen before. I took pictures of the pictures. Seeing family that I have never met is seeing a part of myself for the first time.
Photographs are very special.
