I wanted to combine science and photography in a sensible, unemotional way. Some people’s ideas of scientific photography is just arty design, something pretty. That was not the idea. The idea was to interpret science sensibly, with good proportion, good balance and good lighting, so we could understand it.

I took to photography like a duck to water. I never wanted to do anything else. Excitement about the subject is the voltage which pushes me over the mountain of drudgery necessary to produce the final photograph.

The photograph may be presented as finely and artistically as you will; but to merit serious consideration, must be directly connected with the world we live in.

Actually, documentary pictures include every subject in the world - good, bad, indifferent. I have yet to see a fine photograph which is not a good document.

Pictures are wasted unless the motive power which impelled you to action is strong and stirring.

The camera is no more an instrument of preservation, the image is.
