How do I reduce the rolling shutter effect on the Nikon D800/D800E?The rolling shutter effect means that objects in the frame become skewed and ripple when either the camera or the objects move fast or jittery. Some people refer to the rolling shutter effect as skew, the jello effect or wobble(1). It is especially noticeable during panning shots or fast-moving lateral subjects like trains. The effect is illustrated in the following video. Don't watch it if you are prone to motion sickness. Otherwise, look at the jagged edges that appear at the right side of the tall building. All DSLR with CMOS sensors cameras suffer from the rolling shutter effect but not to the same degree. The pixels on CMOS sensors are read out sequentially, whereas pixels on CCD sensors are read globally. CMOS sensors have a rolling virtual shutter that exposes each pixel separately where CCD sensors expose all pixels in the image simultaneously. Any movement in the image between the first pixel is read and the last pixel is read causes the rolling shutter effect. In theory, that makes CMOS sensors not ideal for video, but the D800 proves it can be implemented very well. The rolling shutter effect is well controlled in the Nikon D800/D800E, compared to other DSLR cameras, by faster readout of the image sensor. General guidelines for reducing the rolling shutter effectReducing the rolling shutter effect all comes down to shooting technique. The D800 has no settings or features to reduce the effect for you. Consider the following general guidelines.
If a fast moving foreground is causing the rolling shutter effectIf you are panning with a fast moving subject, try to track the subject more precise. The requires a lot of practice however. You could shoot the scene more than once and pick out the version with the least rolling shutter effect. An advanced trick for fast action scenes is as follows(2). Test out the amount of skewing that occurs if you record the scene. Now rotate the camera slightly in the opposite direction and record the scene again. With some trial and error you must be able to counteract the effect. The rotated image will make the scene look more dynamic as an added bonus. If a static background is causing the rolling shutter effectIf you are panning a shot and the background is show a rolling shutter effect, you could try the following.
There are various software solutions to lessen the effect in post, some some more effective than others. It is always better to precent the effect form accoring by caryfully choosing the right technique.
