30+ second exposures

Here are a few shots with 3200 speed film using a flash at different points during the exposure. Hey Marshall, thanks for being my muse. blog3.jpgblog1.jpgblog2.jpg

I am an Aunt!

Slow Shutter Speeds and Long Exposure Photography- Photo Tip

Many new cameras will come with built-in shutter speeds of up to 30 seconds or longer, which is enough for most long-exposure photography. Other cameras will have a B (bulb) setting that will keep the shutter open as long as you keep your finger on the shutter release button or a T (time) exposure setting that will keep the shutter open until you press the shutter release button a second time. Cameras with bulb settings can also be fitted with a locking cable release so that it isn’t necessary to keep your finger on the shutter for long exposures. If you camera doesn’t have a cable release, you can use the self-timer option found on most cameras. This will eliminate camera vibration from your hands.

A tripod, or something to rest your camera on, is essential because the camera must be completely still during the time that the shutter is open. If you want to make a fast-moving car blur as it speeds by you, a relatively fast shutter speed of 1/20 of a second may give you the results you are after, however, if you want to make the stars in the nighttime sky look like glowing rings as the earth rotates, you exposure may last all night.

The light meter on your camera may not be able to accurately judge the best aperture setting for longer shutter speeds, especially in low-light situations, so your best bet is probably to “bracket.” This means taking up to six pictures of the same subject, but doubling the shutter speed each time. This will give you a variety of effects and exposures and allow you to choose the best shot. In general, slow shutter speeds will allow a lot of light into the camera, which means that you will want to use a small aperture (ie. f/22) to avoid over-exposing the shot. In bright daylight it will be necessary to use the lowest ISO available and a neutral density filter to cut the light down.

Some great effects and shutter speeds to try are:

Moving stars: several hours

Moving cars at night: 10 seconds

Waterfalls: 4 seconds +

Amusement park rides: 1 second

Fair

December 8, 2007

forblog4.jpgforblog31.jpgforblog23.jpgforblog11.jpg

Here are some images shot at this years South Carolina State Fair. These were all shot with a Holga using 120 Fuji Provia slide film and scanned with a Nikon scanner. These were hand held exposures ranging from 20 seconds to 2 minutes. The fair has a ride similar to a ski lift that takes you over all of the rides. This was a great opportunity to gain an unusually high vantage point, not to mention it was a lot of fun. The only thing that made me nervous was that I have no strap for my Holga, so I was really making a big effort not to drop it. But if disaster did strike, I would definitely shell out another 20 bucks for a new one.
