Vibration is one of the photographer’s worst enemies. Slow shutter speeds and telephotos usually don’t mix well, often resulting in blurry shots. A stable tripod can help to ensure sharper photographs and videos destined for the Web. But what about situations where a tripod is not an option?
That’s where image stabilization comes in.
Once relegated to professional-level cameras, image stabilization technology has trickled down into consumer cameras and lenses. Image stabilized lenses and cameras use tiny gyroscopes to counteract camera motion for sharper shots. If you’re buying a new camera look to see if its got image stabilization inside, it could improve your keeper ratio dramatically. To illustrate how effective image stabilization can be, we’ll show you an extreme example of aerial photography from a vibrating plane.
What Is Image Stabilization?
Image stabilizers work to give you sharper pictures by counteracting camera shake. Image stabilized lenses and cameras use two tiny gyros that precess with camera movement and send a signal via a servomotor to move lens elements, a prism, or the sensor plane in the opposite direction of your camera’s movement. You shake one way, it shakes the other way. Larger gyroscopic stabilizers can steady your entire camera, whether it is optically stabilized or not. For handheld shots with slower shutter speeds or aerial photography, image stabilization is an invaluable tool for damping vibration to minimize motion blur.
Image Stabilization = Smaller Files
Sharper stills and steady videos mean higher quality originals and higher compression ratios. The fewer details per frame and fewer changes between frames, the smaller you can make the file. The sharper your original, the smaller it will be when you optimize it for the Web.
Gyro Stabilized = Sharper Pictures
Unlike optically stabilized lenses which are limited to the same manufacturer (Canon’s IS or Nikon’s VR series), gyroscopic stabilizers can be used with any camera or binocular (stabilized or otherwise) to ensure sharper pictures and smoother pans. Just hook up a gryo, and the entire mass of your camera and lens will be stabilized. Mass stabilization allows slower shutter speeds for special effects; a crisp car zooming along a blurred road for example.
What’s a Gyro Stabilizer?
Gyros consist of a gyroscope with two perpendicular spinning wheels and a battery pack. The gyro attaches to your tripod socket and acts like an “invisible tripod” (see Figure 1).
Figure 1: Ken-Lab’s KS6 Gyroscopic Stabilizer (used with permission)
Kenyon Laboratories offers precision gyros from 1.5 to over 15 pounds that typically stabilize rigs twice their weight. Unlike in-lens systems sold by Canon, Nikon, Panasonic and others, Ken-Lab gyros stabilize the entire camera and lens along two axes. With two precision wheels spinning at over 22,000 RPM, you can feel the steadying power when you hold one. Adriel Heisey used a custom-made plane and a gyroscopic stabilizer to shoot the images for his books on the Navajo Nation and Sonoran Desert. (see Figure 2).

I’ve found that for aerial shots even at 1/1000 of a second gyro stabilization can make a significant difference in sharpness. Figure 3 shows an example of an aerial shot I took with a Ken-Lab KS6 gyroscope.
Figure 3: Heart Island and Boldt Castle – Alexandria Bay, NY – Uncorrected Scan from a Provia 100/1000 slide, Pentax 67 90mm lens, Ken-lab KS6 Gyroscopic Stabilizer
This picture was taken from a Cessna flying over Boldt Castle near Alexandria Bay, New York. Boldt Castle is a popular tourist attraction in the Thousand Islands. Gyro stabilization made this shot possible. Without stabilization, the vibration from the motor and turbulence would blur this shot, even at high shutter speeds. Zooming in on the castle shows a closer look at the castle walls (see Figure 4).
Figure 4: Boldt Castle – Uncorrected Crop
Figure 5: Boldt Castle – Corrected and Sharpened (100%) Crop
Note in the uncorrected crop that the picture looks somewhat washed out, and needs some sharpening. This is typical behavior with PhotoCD scans. Tweaking the image’s levels and curves, and bumping up the saturation, contrast, and sharpening gives the image more punch (see Figure 5).
Drum scans give the highest image density for larger enlargements and higher quality images (150-200+ MB). This shot of one of the Thousand Islands shows what kind of results you can get with a gyroscope and a larger format (see Figure 6).

Zooming in on the photo above shows the effects of the gyroscope. You can see individual leaves on the water, and the planks in the dock below (see Figure 7).

Image Stabilized Lenses
First introduced by Canon in 1993, image stabilized lenses are now appearing in consumer-level cameras. Nikon followed soon after with its “VR” series of lenses, and Panasonic and others now offer image-stabilized digital cameras with high quality lenses (Lumix, etc.). Minolta takes a different tack by moving the image sensor to counteract camera shake. Using these cameras and lenses will improve your photographs, and reduce the number of rejects. The newest models of IS lenses from Canon can even be used on a tripod or atop a gyroscopic stabilizer.
Image stabilization can yield beautifully sharp images at slower shutter speeds. For example, Yann Arthus-Bertrands’ “Earth From Above” was shot using Canon IS lenses and Pentax cameras with Velvia ISO 50 film (see Figure 8).
Yann’s Earth from Above: 365 Days cover shot of a colorful Yellowstone spring was shot from a helicopter using a Canon image stabilized lens (see Figure 9).
Figure 9: Grand Prismatic Spring, Yellowstone National Park, Wyoming, United States (44Â°26Â¹ N, 110Â°39Â¹ W). Situated on a volcanic plateau that straddles the states of Montana, Idaho, and Wyoming, Yellowstone is the oldest national park in the world. Created in 1872, it covers 3,500 square miles (9,000 km2) and contains the world’s largest concentration of geothermic sites, with more than 10,000 geysers, smoking cavities, and hot springs. Grand Prismatic Spring, 370 feet (112 m) in diameter, is the park’s largest hot pool in area and third-highest in the world. The color spectrum for which it is named is caused by the presence of cyanobacteria, which grow faster in the hot water at the center of the basin than at the periphery where the temperature is lower. Declared a Biosphere Reserve in 1976 and a UNESCO world heritage site in 1978, Yellowstone National Park receives an average of 3 million visitors per year. The continent of North America, which contains the five most visited natural sites in the world, is visited by more than 80 million tourists per year â€¹ 11% of world tourism in numbers, but 18% of world tourism in revenues.

If you get the urge to take some aerial photographs, here are some tips for sharper shots:
Aerial Photography Tips
- Isolate yourself from contacting the aircraft, the only thing that should touch the aircraft is your rear end. Sitting on a pillow or other soft object can help isolate your body from motor and wind vibrations.
- Avoid shooting perpendicular to the aircraft’s motion. Shooting forward or rearward minimizes the lateral motion.
- Use the highest shutter speed you can. 1/500 and above is the rule. The lower in altitude, and the longer your lens the faster your shutter speed.
- Use a gyroscopic stabilizer or an image stabilized lens. Even better, combine them for sharper photographs and videos.
- Stay loose. Tensing up will transmit more of the aircraft’s motion to the camera. Use your arms to isolate your camera from the motion of your body.
- Stay out of the slipstream. Keep your camera inside the plane, turbulent air can grab lens shades and shake your shots.
- Have the pilot slow down or fly around a fixed point, once you’ve reached your target. Even better, rent a helicopter for low and slow precision or use a blimp or balloon for a more leisurely flight.
- Use a wide angle lens. Wide angle lenses aren’t as susceptible to motion blur as telephoto lenses are. However, a stabilized lens (like Canon’s 28-135mm IS lens) or a gyro lets you use longer focal lengths to zoom in on your subject.
- Use high contrast film. Some aerial photographers use Velvia (now available in 100 ASA) pushed a stop with fast prime lenses, while others use faster slide or print film for higher shutter speeds.
- Filter haze aggressively. The higher you go and the more oblique the angle, the more air you must shoot through. Haze is a big problem aloft. Use aggressive haze filtering or warming polarizers for color photography.
Wherever your photography takes you image stabilization can improve your shots dramatically. From street-level to aerial photography image stabilization has become a popular feature for photographers. By adding stabilization to the mix, you’ll create smaller and higher quality graphics and videos for the Web.

We are trying to stabilize a digital image using matlab.Any links which would help our cause.
Looking for a large gyro stabilize system for shooting with 1000mm or larger lenses. Possibly remotely operated with joystick and screen. Would like something durable, weatherproof and maneuverable. Cost not a factor.
Hi, recommend you look at the Ken Lab stabilizers at Kenyon Laboratories Gyroscopic Stabilizers. A 1000 mm lens is pretty extreme for aerial photography, so you’ll need a heavier duty gyro stabilizer, like a KS-8 or larger for really steady and sharp images from a moving plane or helicopter.
I’ve used the KS-6 mainly for my medium format work with mid-wide to mid-telephotos. I find that shooting longer telephotos tends to blur the image, and shooting too wide tends to include plane struts in the image so I stick with fast moderate wide to telephoto lenses. The sharper the lens wide open the better, no need for depth of field in aerials, I usually stop down a notch or two to clean up the corners and boost the contrast a bit.
A polarizer cuts the haze and glare and you can push your film or chip to use a higher shutter speed. You want at least 1/500th of a second, ideally 1/1000 of a second or faster.

Can anyone tell me the origins of digital image stabilizer technology? I’m guessing it originated in large telescopes (maybe NASA) and eventually got small and cheap enough to include in mass-market cameras, but I can’t find any information.
“Yann Arthus-Bertrand with Canon IS Lens” that is incorrect, if you look closely it is the 2.8 Non-IS as there is a lack of extra buttons, check this image for comparison http://www.the-digital-picture.com/Images/Other/Canon-70-200mm-L-Lenses-With-Hoods.jpg
Screenworks is a video company that supplies video and large screens for rock concerts. We have two tours out right now (Justin Timberlake and Kenny Chesney) that are using the Sony BRC-300 POV cameras. We are getting vibration that is making the cameras unusable. Can we use your stabilizers to fix this problem? The cameras weighs less than 6 pounds.
I am interested in using a gyro stabilizer for a Panasonic HVX200 HD video camera. Any suggestions on size/manufacturers?
Does anybody know if it possible to use the a gyroscopic stabilizer on an SLR while shooting verticals? All shots I have seen using these products have been strictly horizontals.
In other words, does the gyroscopic stabilizer have to be at the bottom of the camera for it to work or can you turn it sideways as well?
Any comments on this matter will be a big help.
Yes, a gyro will work in verticals as well. Attach the gyro to the bottom of your camera (either directly or with a mounting plate) and
turn your camera sideways. The gyro stabilizes two axes. For still photography this is adequate,
I can shoot at much slower shutter speeds and
still get sharp pictures. You can feel the resistance to motion when you try to pan, it
really is amazing.
I’ve heard that some movie cameraman use two gyros, mounted perpendicular to each other for
even more stability.
Hope this helps.
When using a IS or VR lens I understand if you mount the camera with either of these lenses on a tripod when the stabilization is turned on this can actually increase the vibration and cause the image to be worse than if no IS or VR was employed. Is this correct?
You asked about mounting an IS or VR lens on a tripod and the resulting vibration. This used to be true, but newer Canon lenses have compensated for this and have a couple stabilization modes. They now work on or off tripods.
The ultimate for aerials of course is to use both and IS/VR lens AND a gyro. You could use a much slower shutter speed with this combination and still have sharp shots.
i need some help on the following if possible i have 4 canon xh g1 on a ceiling track we have a large bass sound which is causing vibration in the cameras any ideas or help. also these units have a pan and tilt head attached.
