Wants and Needs...

When I posted about making good purchases 2 weeks ago, I touched on the point that you don't always need to buy what you're considering. Time to explain.

Let's begin with a question: How much stuff do you have lying around the house that you never used, but thought it essential for whatever you're planning? What made you buy it? A television advert? Probably. Maybe you deduced that all this stuff is needed because they always have all this stuff in the movies. You're falling into exactly the trap the marketers want.

Companies want to sell their gear. Gear that is functionally identical to the next company's product. And who will be the softest victim? A layman. "Trust me, you're going to need this." This is usually a lie. Most hobbies or sporting activities can be gotten into without expensive equipment. And if special equipment is needed, such as climbing gear, ice skates, ten pin bowling shoes and balls, there is most likely a company or venue that lets you rent it for a few hours. It makes business sense. They want more people involved so they make the expense of starting out as little as possible.

When it comes to confusing the general public into buying stuff geeks are the biggest offenders. When you walk into a computer store you're bombarded by reasons why your computer isn't good enough and what you can buy to make it better. The truth is most of it does nothing special and you would only notice the difference when you're a semi-professional. You don't need a laser gaming mouse with a specially designed mouse pad and a gazillion buttons if you're only going to play Bejewelled with it. You don't need the fastest graphics card on earth if you just want to play the occasional game. Granted, it won't run as fast or as prettily as the top-of-the-range machines, but with casual games you won't even see a difference.

I have a bad habit. When I discover a new hobby I get into it head-long. I buy everything I could possibly need thinking that this hobby will be my time-filler for the next few years. The remote control car(above) is a perfect example. Buying the car, its controller, batteries and charger, the paint and assembling it wasn't good enough. I had to buy all the modifications needed to make the car competitive on the track. I knew there was an amateur division but I didn't care. I wanted it all! A few weeks of going to the track to practice and subsequently being chased off by professionals, and the novelty had worn off. The car now does what most RC cars do: Race around small traffic cones in the driveway.

So what I do now is ask around. Find out if any of my friends have tried it and if they have the equipment for me to borrow, or know where I can rent it for a few days. Many times my friends say I don't even need all that stuff. Just get the cheapest {name item here} and you'll do fine. The rest can come later.

Most product ranges also have an amateur item in its range. For instance, in the digital photography (I still think that's an oxymoron) industry Canon has the Rebel XT, which costs less than some compact digital cameras and provides all the features needed by even professionals, the main disadvantage being the rate and number of photos that can be taken in succession in a single go. I think 8 megapixel is more than enough for a good photo.

So the moral of the story is as follows: If there's something you want to try but you think it will be expensive, ask around first. See if you can rent what you need, or buy second hand, or borrow from a friend. And most of all, do you even need it all?

Analog to Digital

I've kept the faith for so long, but I knew at some point technology would overtake nostalgia and my beloved SLR camera would be replaced by a digital equivalent.

As with all technology, eventually it will be replaced by something more suitable to our everyday life. The reason I stuck with a film-based camera for so long is called brightness latitude. It's the amount that you can overexpose or underexpose a shot and still be able to recover a good shot from it. The easiest example would be a photo of a candle-lit dinner. If you overexpose the shot your subjects would be well lit, but the candles and the immediate surroundings would "white out", appearing as a bright blob. If you underexpose the shot the candles look great but the table and faces of the people would be in darkness. When working with film, you're transferring light onto a medium. You could then in post-production over- or underexpose certain areas to fix the problem.

An increasingly trendy technique in digital photography known as HDRI has solved this problem. You take 2 identical shots, one under- and the other overexposed. You then overlay the 2 images and select the correctly lit areas from each to create the final image. It's a great trick and can produce some stunning shots, but it usually requires your subject to remain motionless between shots.

Don't get me wrong, digital has its place. You wouldn't want to go all happy snappy at a party with your film camera, simply because it's easier to use a small digital camera. Usually people want to see the picture you just took aswell, and with film you can't show them.

Cheaper digital cameras also don't have a proper viewfinder. You're forced to use the little LCD screen on the back. Any photographer worth their salt will perhaps use the LCD for composition, but will always refer to the proper viewfinder before taking the actual shot. This is why I originally bought an SLR camera, because what you see in the viewfinder is what comes out. With cheaper cameras the viewfinder is slightly offset from the photo lens and can be very annoyingly uncalibrated.

Yesterday I spent about an hour messing with one of the latest dSLR cameras and for the first time I felt like this camera was capable of expressing my ideas the way I want, without holding me back. This notion, coupled with the faster turn-around time and generally digital methodology of almost everything these days, convinced me that the time has come.

Like video killed the radio star, so has digital cameras reshaped our notions of photography.
