“I have often thought that if photography were difficult in the true sense of the term — meaning that the creation of a simple photograph would entail as much time and effort as the production of a good watercolor or etching — there would be a vast improvement in total output. The sheer ease with which we can produce a superficial image often leads to creative disaster.”

Ich vermeinte, man verlange physische Determinationen und nicht abstracte integrationes. Es fängt sich ein verderblicher goût an einzuschleichen, durch welchen die wahren Wissenschaften viel mehr leiden, als sie avancirt werden, und wäre es oft besser für die realem physicam, wenn keine Mathematik auf der Welt wäre.
