Method Focus: Shutter Speed

'The Pier'..1/2..f/4.0..24mm..iso100..0.00exp

Today's photo of the day got me thinking about shutter speed. Extending the time your shutter stays open is a fairly easy trick that can be used to achieve that smooth 'milky' water effect. It can also come in handy for other types of shots, it need not only be used for waterfalls and such.


'Spillover 1'..1/500..f/4.0..50mm..iso100..0.00exp


Moving water is a great subject for extended shutter times. The above picture was taken with the fast shutter speed of 1/500th of a second, notice how it 'freezes' the water, you can see individual droplets suspended in air. Personally, I feel this makes the photo image too busy.




'Spillover 2'..1/5..f/22.0..50mm..iso100..0.00exp

Here is virtually the same picture with a slowed shutter speed, notice how the water is smoothed, and you can no longer see the individual droplets. I feel the smoother water effect has a large impact on the overall feel of the picture. One thing to bare in mind when extending your shutter opening times is lighting, the longer the shutter is open, the more light is allowed in, and the brighter your shot will be. In bright daylight, this can quickly become a problem and wash out your photos.

This little trick can be used for more than just water photography, it can be very useful at night, or in other low-light conditions. I switched over to bulb mode to catch these fireworks pictures. When using bulb mode, you have complete control over the shutter, it will stay open for as long as you hold down the button. Any movement here will effect the photo, so I highly recommend not only the use of a tripod, but also the use of a remote to help avoid any movement which may ruin your shot.

So try extending your shutter times, you can get some cool effects that way. Night shots, low light, smoothing water, fireworks, car light-trails, and many more. Experiment, and see if you can discover any new uses or effects.

All images were shot with the flash off

The Pier and both Spillover shots were shot handheld, both Celebration shots were supported by tripod

All images had their size reduced for web posting
