Ask the Experts on the Topic of Distribution and Delivery

NAB 2009 was fascinating with respect to how many customers were looking for solutions and insisting that manufacturers work together to provide solutions, as opposed to just supplying products. File-based workflows were the talk of the town (well, at least the talk of NAB) and there certainly continues to be significant discussion and implementati...

The filming of Lands End to John OGroats

I’ve been here for several minutes now. Standing in the pouring rain with a camera pointing at the road sign for Somerset, the drops of rain tapping on the camera rain cover add a certain atmosphere to the wild track. I stood trying to work out who was the madder, the two cyclists I was waiting for, or me. Here they come, 10 seconds on the tape, ba...

Polecam on Safari

Safaricam"No, you can’t get out of the car", the voice replied. "Why not?’ I asked. "Because you might get eaten by a lion."I put the phone down and contemplated what it was I had just agreed to do.

Its A Bigger DAM Picture

There’s a lot of fuss these days about “Digital Asset Management.” Why? Because organizations (and their hard drives) are busting at the seams with digital assets that are multiplying faster than hamsters at a rave. Many of these organizations already have enterprise management software solutions in place, so DAM often becomes a new, isolated plane...

SRW-5800 Training

“Hi Dave, how was the course?” This is the sort of greeting you come to expect from fellow engineers when you have recently attended a training course. Engineers are notorious for having no “small talk”, probably because our minds are usually concerned with things like volts, amps and ohms… and why that VTR always works on the bench, but fails as s...

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...

Lighting. Back or rim light part 4

In my last article, I discussed modelling of the ‘talent’ by choice of lamp, and careful choice of the horizontal and vertical angle of the ‘key’ light. Having made those choices my next priority would be to choose a ‘back’ light. It is also sometimes known as a ‘hair’ light which gives a pretty good clue as to its function. Just to say that we are...

From the moment we touched down on the rough dirt & asphalt landing strip in the middle of the Masai Mara...

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...

The morality of meltdown

Apologies for breaking away from my usual broadcast-orientated comments but, when looking at the micro of our own world, sometimes big macro economic tsunamis crash in – and can have hugely damaging effects on our own small, flat, micro economic island. I’m writing this over the weekend when the US Congress is deciding whether it should bail out th...
