For centuries, capturing people's likenesses was the privilege of painters. If in this day and age we are fortunate enough to be able to put faces to historical names, we have those great artists to thank for.
But it was also expensive and time consuming to get a portrait made - a privilege only afforded to the rich and famous.
And then some clever people discovered the process of capturing light using mechanical contraptions. All of a sudden, a faster, more affordable and more faithful way of recording faces was created, bringing artistic portraiture to the reach of the common person who can now be made immortal through Photography.
But faster and more faithful does not necessarily mean better - the challenge of capturing a glimpse of another human being's soul remains the same.
