From a Letter to Edward Weston from his Father

You'll not have to change anything about the Kodak. Always have the sun behind you or to the side - never so it shines into the instrument. Don't be too far from the object you wish to take or it will be very small. See what you are going to take in the mirror. You can only take twelve pictures so don't waste any on things of no interest.
