I think Norman Lockyer’s son Jim was more of a photographer than himself. The NLO were recently given his 1898 Kodak portrait camera (bellows camera with roll film) which he used to take meticulous photos all mounted and dated in his albums. We now have six or seven of these which are a magnificent record of the social life of an astronomer of the day! There is a whole album devoted to the 1927 NLO Solar Eclipse trip to Richmond, Yorkshire where they set up their campsite at the Oliver Duckett mound:
