Using Shutter Speed to Control the Look of Your Photo
by: Patty Hankins

Using Shutter Speed to Control the Look of Your Photo
By Patty Hankins & Bill Lawrence

In the last newsletter, we talked a bit about changing the aperture to control depth of field. This time, we thought we would look at the other method of controlling exposure (for a given ASA): controlling the shutter speed.

For any particular level of light and ASA, either film or digital, proper exposure is a function of both the aperture (how much light is let into the camera), and shutter speed (how long the shutter is open to let light shine on the sensor or film). For every f-stop increase in aperture number (i.e. making the aperture smaller), the shutter speed has to be halved, i.e. the shutter remains open twice as long, to maintain the same exposure. So if you've determined that, say, a shutter speed of 1/100 of a second at an f-stop of 8 is a proper exposure, then a shutter speed of 1/50 of a second at f 11 would also give a proper exposure.

So as long as we're maintaining proper exposure, why do we
care about shutter speed? The major reason to think about shutter speed is because of motion, either yours or your subjects. Often, we worry about shutter speed going too low, which could result in "camera shake" if you are hand-holding your camera, and could result in motion blur if your subject is moving - essentially your camera's shutter is open too long to freeze the subject of the photograph. So, if you want to freeze the action of, say, sports or a fast moving animal, you want to have a very fast shutter speed. Also, if you are hand-holding a long telephoto lens, you will want a fast shutter speed since the magnification of the lens will magnify any accidental movements you make.

Other times, a slow shutter speed is desirable to convey a sense of motion in a still photograph. A common use of purposely setting a low shutter speed is to give a sense of flowing water - see the next article about photographing waterfalls for a good example of using this effect. We've also seen some impressive photos of palm trees in hurricanes where a slow shutter speed was used to blur the palm fronds and convey the sense of them whipping in the wind in a still photograph (sorry, we don't have examples of these to show you - we try to avoid hurricanes). A slower shutter speed can also be used for a technique known as panning, where the photographer moves the camera to track a moving subject, which (if done well) results in a sharp subject but a background blurred by motion (this is a common technique for those photographing birds in flight and for those photographing racing cars).

To experiment with shutter speed, you will need a camera
that can go off of full automatic, and let you set the
shutter speed, either in full manual mode (you set both the aperture and the shutter speed), or in "shutter-priority" mode, which is an automatic mode where you restrict the camera to one shutter speed. A word of caution about shutter
priority: most camera lenses have less flexibility with the amount they can vary apertures (remember, this is the other part of getting a correct exposure) than your camera has with setting shutter speeds, so you have to make sure that you can get a correct exposure with the shutter speed you set. For example, if you try to take a photo on a dark night in shutter priority mode with a shutter speed of 1/1000 of a second, your camera will be unable to open the aperture enough to let in enough light for this shutter speed, resulting in an underexposure.

To experiment, simply find a subject that is moving, and try some exposures at different shutter speeds to see the results. Remember, for low shutter speeds, you will want a tripod to steady the camera. Visit our website for an article thatshows how different shutter speeds give different results for water flowing over waterfalls.

 Skateboarding - One of the Most Exciting and Skilled Board Sports
 by: Ben Ruhland

If you’re looking to get into a board sport why not try out skateboarding? Let me guess you and your friends go out on weekends looking for something to do but you’re bored stiff. Well I can guarantee you skateboarding is a sport you’ll never be able to give up on once you get into it. It’s a board sport that can have a steep learning curve depending on the person but most people can pretty much master the basics within a couple of months.

Skateboarding has developed quite a bit in recent years. For decades when skateboarding was in its infancy, it was seen as an activity performed by youngsters, mainly rebel kids. In these earlier years skateboarders were perceived as outcasts who went around vandalizing other people’s property by skating on it. It is becoming more understood these days but it still has a long way to go before people will fully understand the skill and dedication that goes into this sport.

The basics of skateboarding like pushing yourself along the street are easy to learn but once you get into the tricks and manoeuvres such as the most basic trick, the ollie, it takes quite a bit more practice to master. You need to learn the ollie as it’s a fundamental move that is combined into the majority of tricks where the board leaves the ground. The ollie is what could be considered a “jump” where the skateboard and the rider leave the ground with the board under their feet. To really master this basic move it can take a natural skater up to a year to really get it down.

When learning to skateboard some protective gear can go a long way to ensuring your safety as you can expect to take many falls when first starting out. A decent helmet, some elbow pads and knee pads will give you the safety you’re looking for and a little extra confidence knowing you won’t get too hurt when you fall. You can buy this protective gear fairly cheap from most skate shops and even some general purpose stores.

It’s easy to get nervous when first starting out on a skateboard because your balance will most likely be very out of tune. But don’t worry, every single skater you see out there on the skate park doing all those big moves, grinding rails, doing big grabs on the half pipe, they were all just like you when they started out. It’s a sport that takes a lot of dedication, and it relies on practice. If you put in the hours you’ll be popping kick flips in a matter of months. So go out there and get practicing, it’ll keep you busy for many years to come.
