Quoted By:
My father was a laboratory worker in a concrete plant in the 90's. I don't remember which cameras he used, there were many, but the ones I was able to recover were an Olympus Pen F, a YASHICA Electro 35 and a Nikon F-401x. In this photo is a sample of the quality result of one of the concrete extractions. Can it be "deduced" which camera was used?
