BBC One Show – Alex Jones – Mother of All Challenges
We were hired to film aerials for the BBC One Show’s Mother of All Challenges with Alex Jones for Sports Relief at Dorny Lake which was the venue for the 2012 Olympic Rowing.
The shots were used for the event promotion and general advertising, One Show and Sports Relief social media campaigns. Full details about the challenge can be viewed on the Sports Relief website here: www.sportrelief.com/news-and-tv/mother-of-all-challenges

Hot Spot, Bypass Diode or PID: Reading Solar Panel Thermal Signatures
A thermal image of a photovoltaic array records surface temperature, and surface temperature is a symptom rather than a diagnosis. This post sets out how the signatures are actually read on an operating array: what a single hot cell suggests, why a uniformly warm third of a module points somewhere entirely different, how potential-induced degradation gives itself away by geometry, and why severity under IEC 62446-3:2017 is framed with caution rather than asserted from one temperature figure.
Following the Water: Gutters, Valleys and Where a Roof Sheds Rain
A roof moves rainwater along a designed path, from slope to valley to gutter to outlet. Autumn is when that path is loaded for the first time in months, and when anything silted, sagging or split begins to show. Almost none of it is visible from ground level. This is what an aerial inspection records about roof drainage, why standing water is such a useful signal, and how observations are marked on the imagery so a contractor can quote from them.
Radiometric Thermal Imaging: Why a Thermal Image Is Not a Temperature
A thermal camera does not measure temperature, it infers one from the radiation reaching its lens. That inference depends on emissivity, reflected apparent temperature, distance and the state of the air in between, all of which the thermographer supplies. Get them wrong and the camera still reports a confident figure. This piece sets out what has to be controlled to make a thermogram measurable, why it matters more on some surfaces than others, and what to ask a supplier.
