Troops advance in the teeth of a barrage of white phosphorus during a demonstration of chemical warfare at an eastern arsenal. White phosphorus is a deadly incendiary, but it also produces clouds of white smoke when it reacts chemically with oxygen in the air. Our chemical warfare experts work quietly without fanfare to keep two jumps ahead of the enemy in this type warfare. So far, the enemy has refrained from using poison gas, but if he provokes use of that weapon we are better prepared than he to fight it, November 1943.

Ferrotyped prints are processed in such a way that they are shiny. The print has a sensitive surface, usually thinner, because it was put through a press while still wet.

Ferrotyped prints have a sensitive surface, usually shiny and thinner, because they are put through a press while still wet. Ferrotyping makes the surface of the photograph smoother. Light does not scatter as much on a smoother surface, so this increases contrast. That makes ferrotyped images better for press photography.
