ZSL London Zoo Am I understanding this correctly?

[Pertinax]

I imagine this photography business has come about because ZSL is the capital's Zoo and so more tourist-orientated than elsewhere, certainly a high proportion of their visitors are tourists, often foreign.

Bristol Zoo and the National Marine Aquarium at Plymouth do it too. I'll bet that there are other places doing it already or considering it - it doesn't cost much and I'm sure it's a nice little earner.
