Quoting wikipedia (https://en.wikipedia.org/wiki/Lewis_Carroll):
> Several other writers and scholars have challenged the evidential basis for Cohen's and others' views about Dodgson's sexual interests. Hugues Lebailly has endeavoured to set Dodgson's child photography within the "Victorian Child Cult", which perceived child nudity as essentially an expression of innocence.[88] Lebailly claims that studies of child nudes were mainstream and fashionable in Dodgson's time and that most photographers made them as a matter of course, including Oscar Gustave Rejlander and Julia Margaret Cameron. Lebailly continues that child nudes even appeared on Victorian Christmas cards, implying a very different social and aesthetic assessment of such material. Lebailly concludes that it has been an error of Dodgson's biographers to view his child-photography with 20th- or 21st-century eyes, and to have presented it as some form of personal idiosyncrasy, when it was a response to a prevalent aesthetic and philosophical movement of the time.
