Adendum (sobre los experimentos)

Hay algo que olvidé. Un aspecto que creo importante a tener en cuenta con cada experimento es el saber perderse en él, dejándose llevar por lo que éste va ofreciendo a cada paso. Pero teniendo cuidado en dejar un trazo de la ruta seguida, para luego poder salir cuando sea necesario.

Con los experimentos, como en la vida, hay que ser precavido pero algo irresponsable. Ningún extremo es bueno. Ni malo.

"Again accident came to his aid. One evening Daguerre placed in a cupboard one of his silver iodine plates that had been exposed, and left it overnight. In the morning, on taking it out he was amazed to find that a picture had been developed on this plate. That day he exposed another plate, and, leaving it in the same cupboard, beheld next morning again a picture. How or why this had happened was beyond Daguerre’s imagination, but he set himself methodically to find out. In the cupboard were a quantity of chemicals of one kind and another, and Daguerre believed it was the vapor from one of these which was responsible for the seeming miracle. At last it became certain that it was a dish of mercury which had wrought the change, and so Daguerre discovered that he could develop an exposed plate by placing it in the dark, face down, over a dish of warmed mercury."
