When I started clearing my loft, I discovered a box of old photos in APS format. No, I don't mean they were taken with a camera with an APS-C-sized sensor. I mean that they were taken on an APS camera. Onto APS film.
It struck me that some folk might not remember the last hurrah of the film era, because it never really got close to unseating 35mm before digital cameras came along and did that instead. Now we remember APS and its three different sizes more through reference to image sensor size than we do the film itself.
