Some pretty good retouching, too. I recognise the Darwin one as being taken by Julia Margaret Cameron while he was visiting Dimbola Lodge at Freshwater, IOW. For those interested, the artist who did the recolouring is Sally Dullaway.

Perhaps she doesn't? ~ but the colours & tones do look pretty accurate! hahaha.
