Brace Yourself (and Your Camera):
Steadying You and Your Gear for Sharper Photos
Most of today's cameras and films/digital sensors produce superbly sharp photographs. If photographs are fuzzy, that problem is usually due to operator error. Fuzzy photos happen because of incorrect focusing and camera shake. You can generally take a handheld photo that's sharp if you use a shutter speed that's faster than the focal length of the lens. For example, if you are using a 50mm lens you can select a shutter speed of 1/60th of a second (which on most cameras is closest to the number 50), or 1/125th, 1/250th, etc., and generally get a crisp, sharp image. If you use a shutter speed of 1/30 or longer, you may get some blurry photos unless you use some of the techniques listed here for bracing a camera. With a 500mm telephoto lens, you must use a shutter speed of 1/500 of a second or faster. In summary, you will generally get sharper handheld photos with a wide-angle lens as opposed to a telephoto lens.
If you're traveling by boat, airplane or automobile, you'll need to use high shutter speeds such as 1/250 or faster because of movement/vibration of your means of conveyance. Tripods are useless in such situations, because of the shake of the vehicle. (Some camera manufacturers manufacture telephoto lenses with built-in gyro-stabilizers for extra stability in these situations. If you're a serious photographer, the investment is well worth the extra cost.)
Here are some techniques for reducing camera shake, from minimum to maximum "hassle."
Handholding a Camera
- · Be conscious of your breathing. Rather than holding your breath, which creates tension and hence body shake, take an easy, relaxed breath, and let it out slowly. At the end of the breath, snap your photograph.
- Keep your body loose, with knees slightly flexed and feet spread slightly apart.
- Elbows should be in. When taking a vertical (up and down) photo, this is especially important.
- You can use your body as a camera brace. Try kneeling on your right knee, and use your left knee as a brace for your left elbow of your arm that's holding the camera. Also, you can sit, with both knees up, using your knees as a brace. Or, for maximum stability, try getting in a prone position, with your body flat and both elbows on the ground.
- If you have a camera with a motor drive and don't mind "burning up" film, you can click off a quick series of photos. Your first several frames will be throwaways, but you may get a sharper photo by the fourth or fifth frame because of your breathing/body position. This is an expensive and marginal technique, but sometimes works when you have no other options. Fortunately with digital this option is more financially viable.
External Supports
- Brace a lens using existing supports. Lean against a wall or tree. Rest your camera on a log, rock or railing (use a jacket or camera bag to protect your camera from the abrasive effects of rocks). When you're using a "spongey" support such as a jacket or camera bag, push the camera down onto the support.
- Professional sports photographers sometimes use a "monopod," which is like a tripod, but with one leg. This system combines some stability with ability to move your camera.
- A small "tabletop" tripod is inexpensive, portable and great for small lenses and macro photography. Such tripods won't work with big telephoto lenses.
- Use a cable release when making long exposures with a tripod. This is a cord or wire that attaches to your camera, enabling you to trip the shutter without touching the camera.
- The larger and heavier your tripod, the more stability you have. Of course, If your tripod is too large, you won't have it with you in situations such as backpacking. So evaluate your needs and buy a tripod accordingly. You may want to get several tripods.
- In extremely challenging situations, such as using a tripod in windy conditions with a long telephoto lens, you may want to weight the tripod down with your camera bag, a bag of sand, rocks or snow. Also, with long telephoto lenses, use the tripod mount on the lens (if available) rather than the one on the camera.
- Getting sharp images when using shutter speeds of 1/8 to1/30 of a second can be especially challenging. Why? Even with a tripod and cable release, there's enough motion from the cable release/shutter action/mirror motion to cause a tiny bit of camera shake. There are several solutions to this: Use a faster shutter speed if you have enough light. Or you can use a longer shutter speed, such as 1/2 or 1 second-or even longer, so that the release of the camera shutter and mirro has less over-all effect. During long time exposures such as 30-second or one-minute exposures, you can quickly place a dark card, wallet or other object in front of the lens at the moment you trip the shutter, and again at the end ofthe exposure, thus negating the effects of shake from the camera shutter/mirror. Finally, some high-end cameras feature mirror lock-up, so that before you make your exposure, you lock the mirror.
