"Data means information which – (a) is being processed by means of equipment operating automatically in response to instructions given for that purpose, (b) is recorded with the intention that it should be processed by means of such equipment, (c) is recorded as part of a relevant filing system or with the intention that it should form part of a relevant filing system, (d) does not fall within paragraph (a), (b) or (c) but forms part of an accessible record as defined by section 68, or (e) is recorded information held by a public authority and does not fall within any of paragraphs (a) to (d). " IANAL, but my non-professional understanding is that constantly recording like this, if you're only going to be manually looking through the way his partner does, isn't covered as "data" under this law. (Section 68 is not relevant either in this case, http://www.legislation.gov.uk/ukpga/1998/29/section/68 http://www.legislation.gov.uk/ukpga/1998/29/section/68) edit: in reply to your edited in link, there's a big difference between filming to distribute (e.g. movies) vs. filming for personal record (e.g. tourists taking photos).
