Well, as has been said earlier, these types of photos are something of a holy grail of the ENF genre and there is a reason for this. If it's a posed professionally modelled picture then most will consider it inadmissable, otherwise it treads dangerously close to the HNF line instead. This only leaves a very fine spectrum of "slightly reluctant but not too bothered about the situation". I somewhat doubt that the ideal picture you're looking for will actually exist.
