"Photographers deal in things which are continually vanishing and when they have vanished there is no contrivance on earth which can make them come back again."

Henri Cartier Bresson

"First you imitate, then you innovate." Miles David

'The theory of photography can be learned in an hour and the elements of practising it in a day … What cannot be learned is the sense of light, an artistic feeling for the effects of varying luminosity and combinations of it, the application of this or the effect to the features which confront the artist in you. What can be learnt even less is the moral grasp of the subject – the instant understanding which pus you in touch with the model, helps you to sum him up, guides you to his habits, his ideas and his character and enables you to produce, not on indifferent reproduction, a matter of routine or accident such as any laboratory assistant could achieve, but a really convincing and sympathetic likeness, an intimate portrait.'

1856, Nadar
