A day in the life of a TV lecturer

0830The Dorset country lanes give way to the flood of traffic into Poole and Bournemouth as I negotiate the rush hour streaming into the seaside town. Driving past Poole Harbour, home of Sunseeker Yachts and the RNLI reminds me that yacht I once dreamed of is still a dream. However, the job I once dreamed of became a reality when I became a televis...

NAB 2009 report

By general consensus, this year's NAB Spring Convention, or 'NABshow' as it styles itself, was one of the best ever. Wider aisles and a respectable rather than manic level of attendance made the event, in the words of one exhibitor, 'Business Class'. NAB was always the prototype show where you could sense the directions in which manufacturers were...

From little acorns....

So what do we do? We have done little for television – our market place is much more modest. Parafotos has its origins in the early sixties when I started filming free fall parachuting– having to cope with a Bolex H16 strapped to the side of my helmet during the opening of the parachute was an interesting experience which no doubt accounted for an...

Red One Hit or Myth

So – after having arrived a year ago to these shores the Red is starting to settle into everyday living here in the UK. Possibly being American and designed by an iconic trendy sunglasses designer, we shouldn’t be surprised by its many foibles.

Fibre Optics......the past, present and future

The future of Audio

Total audio has been around for 12 years now and I worked for the BBC for 13 years prior to that, I resigned in 1996 as a senior sound supervisor based at Pebble Mill. I firmly believe that sound is only noticed twice, the first time it was distorted and the second time it wasn’t there. When it all goes swimmingly it’s rarely mentioned. In the last...

Camera rigs and lighting

The biggest single story at IBC this year, apart from the usual company-eats-company rumours, was the continuing progress of stereoscopy or '3D' as it is currently undersold. A stereoscopic snapshot may well be 3D (displaying length, width and height) but a stereoscopic movie is in fact 4D as it includes a timeline. John Logie Baird set the stereos...

Everything you ever wanted to know about TV lighting Part...

Back in time in the days of monochrome TV, portrait lighting was used to try and compensate for the lack of colour in those days of flickering 405 line pictures on tiny screens. The other consideration was to compensate for the lack of depth; the missing dimension from our TV screens. When colour TV came along in the 1960’s, pictures looked more re...

How we lit Mick

Shine a lightLets start at the beginning with the most fundamental, basic of questions – what’s the point of lighting anything, let alone a living legend like Sir Mick Jagger? The answer is simple – because lighting is the most important part of the whole process. Not the filming. Not the fiddly edit. Not the chin-scratching pre-production. The lig...

When trouble looms phoenix your company

So, the US Federal Reserve (broadly equivalent to the Bank of England – it influences the availability and cost of money and credit in the US economy) is about to bail out Fanny Mae and Freddie Mac, the two largest US mortgage providers. This comes on the back of the Bank of England helping, in no small way, Northern Rock. One rule for them, anothe...
