I still think it is logical to start with establishing a photography interest group, with a series of open knowledge projects supported by Wikimedia UK, and then have the interest group advising as to budget and propose kit we might have an a (WMDE style) loaner library.
At the moment we have yet to even fork out 15 quid on a cheap but effective portable light box; as nobody has actually followed through and proposed it.
