Thirty years ago, television captions were routinely created by sticking white Letraset characters onto black card.

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


In my last article, I talked about some of the basic technical aspects that we need to think about when we start on the lighting trail.

Everything you ever wanted to know about lighting Part 1


Anyone starting on the long and winding road of lighting might well be baffled at the number of very different approaches that he or she might find in books and articles. I certainly did, and that was probably because my training in Television had been engineering based, where the very nature of engineering provides specific answers to specific pro...

A hidden beauty


The lifestyle of the Wildlife cameraman (and woman) you’d have thought, and I was hoping, was all exotic locations and beautiful scenery. Except for me the reality was a murky, water filled quarry during a very cold winter and early spring of 2006- 07.

The Benefits of Lens Add-ons


Zoom lenses on broadcast and professional video camcorders are wonderful tools for the videographer, allowing quick and easy focal length change. But ultimately, a zoom lens is limited on both the wide and telephoto end of its zoom range.

Quality Assurance for Digital Production Workflow


In every industry that I’ve had anything to do with the word ‘Quality’ gets backs up faster than just about anything else. Well, perhaps some parts of the automotive industry are amenable but then they largely invented the concept in the last century. Perhaps it would help to start off with a definition. After all, the word means many different thi...

One man and his boat


It all started when I decided to build a boat in the garage. A fifteen-foot gaff rigged pocket cruiser to be precise. I bought the plans from a naval architect in Wiltshire and had the hull planks computer cut by a specialist boat builder in Kirkcaldy.

Chromakey tips and tricks.


Chromakey is one of those slightly magical effects that can still bring out the child in all of us. Also childlike are the frustrated tantrums you throw when you have been trying for hours to get a decent key, and realise you will have to pay some compositing wizard to rescue the shot.
