This Photopia colour slide is one from a series that I've had a very long time, and occasionally I scan another and publish it. The colour is very washed out, but any colour that is present had to be coaxed out of the scan with the histogram controls on Silverfast, because when you look at the slide in daylight it's basically red.
The location is on the rocks below the Royal Citadel in Plymouth, and although I don't know the date I would guess from the fashions that these photos were taken in the 1950s.
