Mr. Calvin Soo and his 1989 Toyota firetruck.

Yes, it’s backwards. All lenses project an image that’s upside and backwards. Modern cameras use mirrors to correct the image vertically and laterally so this is a quirk that takes some people by surprise. The ambrotype images I make are positive images created in the camera and there is no facility for correcting the image laterally after the fact. So, every image you see in my collection is backwards!
