While doing my MA in Photography we discussed these issues with Roger Taylor (then a visiting lecturer):

Roger Taylor the Photo historian edited and wrote text for a definitive book on the work of Charles Dodgson around 2002/3, published by Princeton University Press. The research was extremely thorough based on the Dodgson archives held at Princeton and for the first time photographs/negatives were cross matched to the entries in Dodgsons diaries and other papers.

The images of Alice Liddell were made over a short period of time and her mother was always present, every sitting was deatiled in the diaries. What hadn't been realised was at that point there was craze in Britain for cards of paintings of young girls similarly posed, and Dodgson is thought to have seen the commercial possibilities. We think of the Victorian era in Britain as being moral and puritanical but that wasn't always the case.

So Dodgson may well have been stupid in his actions in hind-sight but there was no evidence of anything else, his meticulous cataloguing of his negatives and his diaries showed clearly these images were only made in a few sessions and not over an extensive period of time.

That's well put in light of what researchers found.
