Ironically, even if the camera is rock solid and doesn’t move, the IS system may go into something called a feedback loop, in which the camera’s IS system essentially detects its own vibrations and starts moving around. If not, the system will constantly try to correct for movement and can actually soften images. If you put your camera on a sturdy tripod, you’ll want to turn IS off. There is a time and place to use IS and a time to turn it off. Image stabilization is a wonderful tool that can really improve the sharpness of your images but be careful. Some of the newer lenses are now smart enough to detect whether the camera is being held horizontally or vertically and will automatically disable IS for the axis that’s parallel to the direction of the pan. This is an important distinction when you want to pan your camera while shooting a moving subject like a runner, sports car or anything moving horizontally across the frame. (Vertical movement is called “pitch” while horizontal movement is called “yaw”) Another mode corrects only vertical movement. In the Canon world, if you have two modes, you’ll find that in one mode the IS system will correct for motion both horizontally and vertically. Read your user manual for your specific lens to understand what your IS system does. ![]() With some lenses you can only select On or Off, while others offer various modes of operation. ![]() The problem is that, while setting up a new camera for the first time, many shooters turn the camera or lens. Image Stabilization systems vary greatly, not just between manufacturers but also between individual lens models. Complementing close-up shooting, an Image Stabilizer is featured that minimizes camera shake by two stops at full 1:1 magnification, or up to four stops at. Add image stabilization into the mix and suddenly you can capture sharp images of still objects with a 500mm lens at speeds down to 1/60-second, a 300mm lens at speeds down to 1/30-second, and a 20mm lens at speeds down to 1/2-second. But remember, this only corrects camera motion, not the motion of your subject. Blendshape: This is the name of the blend shape in a 3D model that we want to map with the current expression’s blend shape. Scale Parameter: Is used to multiply a facial expression’s weight. Today’s IS lenses can detect and correct for camera motion well enough to allow you to use shutter speed two to four stops slower that you might otherwise. Source: Lens Studio This is how you can change custom settings by modifying Scale and Blendshape parameters. ![]() A microprocessor in the lens analyses the data and moves the IS lens group at a speed and direction to counteract the camera movement. Two gyro sensors - one sensitive to horizontal movement and one sensitive to vertical movement - detect the speed and angle of any camera movement. The IS technology instead introduces motion into the camera using a special IS lens group. But with this technology they accepted the fact that this is often easier said than done. It was always thought that the only way to reduce or eliminate camera shake was to stop all camera motion. Pentax K200D 10.2MP Digital SLR Camera with Shake Reduction 18-55mm f/3.5-5.6 Lens in the Digital SLR category was listed for R2,250.00 on 9 Jan at 10:01 by. We’re Canon shooters so for this article we’ll us IS but the concepts are the same.) (In the Canon world it’s called Image Stabilization in the Nikon world it’s Vibration Reduction. Photography is a specialised skill and you need to follow some rules.
