Improve your photography The last few years has seen an explosion of star photographs, made possible by ever-improving DSLR cameras able to operate at high ISOs; but capturing an eye-catching image requires the right equipment, a good deal of preparation and the ideal location, as well as the correct technique. What do I need? A tripod is essential, as is a cable release – just the action of pressing the shutter button will be enough movement to render the shot useless. You can buy a cheap generic cable which plugs into your camera, or splash out on a fancy remote…

Words and pictures by James Gifford. Landscapes Patience is a Virtue Perhaps more than any other genre, landscape photography requires an artistic eye to create the best composition; but having the technical knowledge at your fingertips is equally vital, as is having the patience to wait for the perfect light. Some professional landscape photographers might spend several days at one location, waiting for the optimum combination of soft light and dramatic sky which can elevate a good composition into an award-winning photograph. But, for enthusiasts with less time on their hands, there are several tips worth bearing in mind. Think…

Words and pictures by James Gifford. Take control Probably one of the least understood and under-used aspects of a DSLR camera is its metering ability; but it’s not as complicated as it sounds. Grasping how to use it can ensure that your photographs come out exactly as you intended. If you read my column on Aperture and Shutter Speeds in the April issue, you’ll remember that if you switch to Aperture Priority shooting mode (A or Av), once you’ve chosen the aperture, the camera selects the appropriate shutter speed to ensure that the picture is correctly exposed – and similarly…

Words by Keith Duffield. A guide to licence-free 2-way radios Until the mid 70s, private radios weren’t available to the general public. Then CB (citizen band) radios became legal, and SA went crazy – we now had CB radios just like in the movies. If you didn’t have a 3 m stainless steel whip on your vehicle, you weren’t part of the scene. But it wasn’t long before the novelty wore off; and as the years went by, CB radios all but died out as a means of private communication and as a hobby. Fast forward nearly forty years, and…

Words and pictures by Dave Miles. I drive an ’07 Hilux DC. After years of deliberation, I still couldn’t decide how best to kit out my Hilux. The problem was that every arrangement had its pros and cons, but I was stuck on the most basic question: Where should I sleep? At first, I thought a canopy with a rooftop tent would be a good idea, but then I got to thinking that a ground tent might be best, or perhaps the tent should be mounted on the Hilux’s roof. Fortunately, my uncertainty came to an end when I joined…

Words and pictures by Grant Spolander. Why turbochargers fail, and how to prevent this from happening to your engine. In this final part of our two-part turbo feature, our Technical Editor, Grant Spolander, investigates common causes of turbo failure and how to prevent them, and what to look out for when purchasing a used turbo-diesel vehicle. In last month’s issue we dealt with the basic principles of turbocharger operation. We also touched on the subject of reliability, highlighting the fact that these high-speed units demand optimal running conditions. Generally speaking, turbochargers are dependent on two lifelines: lubrication and cooling. The…

Words and pictures by James Gifford. Black and white photography. It’s a familiar scenario for every aspiring photographer: you’re sitting in front of the monitor, wading through the thousand-odd images you took on your last trip and trying to cull them to a more manageable number. You know that the image in front of you shouldn’t make the cut, but instead of deleting it, you think, ‘Maybe I can rescue it by converting it into black and white.’ Don’t fall into the trap! Although a quality monochrome image will look better in black and white than it would in colour,…

James Gifford On Your Doorstep! With the bounty of big game opportunities spread across southern Africa, it’s easy for wildlife photography enthusiasts to forget that there’s a fascinating miniature world, with an infinite supply of photogenic subjects, right on their doorstep. Not only is staying home cheaper than travelling to a national park or private concession, but you also don’t have to spend hours traipsing around in search of a suitable subject, only to find that it’s sleeping or in terrible light. Animal, Vegetable or Mineral It‘s amazing how many eligible subjects you find lurking around every corner as soon…

Words by Grant Spolander Pictures by Grant Spolander and Jess Fogarty.On its release in 2010, the Amarok pioneered several technological developments within the double-cab market. As the climax of this evolution, VW has now launched an Amarok in automatic guise; a vehicle that will once again stir the pot of progression. Our Technical Editor pitted this model against the highly acclaimed Ranger 3.2 AT. When we first heard of the new Amarok and its 8-speed automatic transmission, we had a sneaking suspicion that it would make a great tow vehicle. But the only way to know for sure was to…

Words and pictures by James Gifford. Confused? When you buy your first DSLR camera, all its functions can seem pretty daunting; a fact which is not helped by an instruction manual which appears to be written in a different language. The temptation is to switch everything to automatic or – if you’re feeling really adventurous – choose the ‘stick-figure’ running man on your mode dial. While you might end up with some reasonable images, an understanding of the concepts of aperture and shutter speed will allow you to choose how to portray the scene, and dramatically improve your photographs. It’s…
