Exploding bombs frequently caused so much vibration of photo enlargers that prints blurred and had to be remade
The Pacific War Photographs of Pfc Glenn W. Eve — "In the summer of 1942, the U.S. Army called up a skinny California boy barely out of his teens. But at 5’9’’ and 125 pounds, Private Glenn W. Eve was deemed unfit for combat. He might have spent the duration of World War II at a desk, except that he had field skills the Army needed – he was a gifted artist, draftsman and photographer who'd spent the previous four years working for the Walt Disney Co. In July 1944, they promoted him to private first class (Pfc) and assigned him to the Signal Photo Corps, bound for the Pacific to document the war. This is his collection, never before published. All comments in quotes are Pfc Eve's, written on the back of the photo."
Japan Air Raids "is an ongoing project to build a digital archive dedicated to the international dissemination of information about the World War II air raids against Japan." They have seeded it with quite a bit of material (e.g. Target Tokyo, narrated by Ronald Reagan in the documentary and propaganda section) and promise there is much more to come.
