I have some old negs from early 1900's that were taken in Finland. This is large film, something like a Kodak 616 type. This neg is very thin and when I viewed it in bright indoor light looked normal but when I view it in subdued light at just the right angle it looks like a B&W neg. I can actually see the positive of the image. Has anyone seen anything like this before, really kind of strange.(posted 8050 days ago)Richard
