Pushing Air- the art of acoustic design

Acoustics is usually regarded (or often disregarded) as a black art that is practiced with no discernable science involved, with a great reliance on ears for measurement and blind faith as a method statement. Nothing could be further from the truth in the professional study of sound, with many practitioners furnished with several degrees and a weal...

Double dip 2009

Well here we go again. Christmas is coming and, yes, given market reactions and the news that Dubai’s bubble has burst, it looks likely that we are heading for the classic W – two falls into recession, a double dip.

Lighting series

So far in this series, I have stressed some of my own preferences for good portrait lighting; using Fresnel lamps for key lights to enable accurate barn dooring, minimum spill light and an even ‘field’ of light. Open faced lamps, whilst cheaper, do not give the same control of light, they give rise to double shadows and are also prone to bubble fai...

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.
