Photographs capture a moment in time.
They freeze it, and preserve it long after it has passed.
Photographs can bring back that which no longer exists.
They can bring back that which the world has forgotten.
They allow us to travel back to a moment in time after it has long gone.
They capture the dreams and hopes of the past, even if they have faded in the present.
Photographs allow us to travel back in them.
The world and people in photographs may change, but photographs themselves never do.
A photograph can take you back to a sunny picnic between close friends, a wedding, a birthday, or a flash of lightning.
