How To Stop Camera Shake

Camera Shake

The phenomenon known equally camera shake is caused by motility of the photographic camera (hence the proper name :-)), which becomes noticeable as blur when using a slow shutter speed. The resulting blur is not quite the same as the blur acquired past wrong focusing.

How tin we tell the deviation between blurred focus and camera milkshake?

Accept a expect at the picture on the correct. Hither nosotros have a mixture of mistiness caused by the subject moving, blur acquired by the camera moving and the mistiness of the background which is out of focus. The focus is really precipitous on the main subject, but you'll have to take my word for that :-). Y'all can meet the difference between the ii types of mistiness if yous expect closely, rather than a full general fuzziness, movement blur looks more than like a double exposure or a serial of exposures. If you expect at the back wall in this first picture yous can encounter both types of blur. The wall is 'soft' due to being out of focus but also there is a double, or triple, image which is caused past photographic camera movement.

Motion mistiness, whether it is acquired past movement of the subject or movement of the photographic camera, looks the same. Although some of the movement is caused by the guitarist moving, the microphone, which wasn't moving, is blurred too, as is the background, this is due to camera shake.

Have a wait a this 2nd photo, The photo is now generally sharp because I have used a flash, and therefore a much faster shutter speed, merely the wall is still blurred because information technology is out of focus. I recall if you look at the green tiles in both pictures you can see the dissimilar types of mistiness quite clearly.

Whereas blur caused past motion of the bailiwick can be desirable, sometimes, to assist create 'atmosphere' in a movie, camera milkshake should be avoided in all simply the most 'arty' type of photos.

Why do we get camera shake?

No thing how conscientious we are, when we press the shutter push there is ever some movement of the camera. At faster shutter speeds at that place is no noticeable effect on the picture but at slower speeds the blur becomes credible. The manner we stand, the way we agree the camera and how vigorously we press the shutter button all take an effect on the amount of move we get.

How can we avert movement blur from camera shake?

To eliminate the mistiness nosotros tin can exercise several things:-

1. Apply a faster shutter speed and/or a shorter lens.
2. Use a tripod with or without a remote release.
3. Brace ourselves every bit best we can confronting a wall or other object to minimize movement.

1) Faster Shutter Speeds

The virtually obvious mode of eliminating shake is to utilise a faster shutter speed. Either by opening the aperture wider or introducing more light by using a flash gun for instance.

The dominion of thumb for a precipitous picture, free from the furnishings of camera shake, is to apply a shutter speed which is at least equally fast as 1 divided past the focal length of the lens. So if you are using your zoom set at 100mm y'all should use a shutter speed of at least 1/100 of a 2nd. If y'all are using a 50mm lens you will become a sharp pic at 1/50th of a second.

The reason why the focal length of the lens is of import is that photographic camera milkshake becomes more than credible equally the bending of view gets narrower, the narrower the bending of view the more the shake is magnified. Y'all will know this if you take always tried to agree a telescope or a loftier powered pair of binoculars still.

ii) Sturdy Tripod

Putting the photographic camera on a sturdy tripod is the best way to keep it nonetheless and this is the way to go, especially when you want to get some motility blur from the subject like in the waterfall picture here. Even ameliorate is to get a remote release for the photographic camera so yous don't have to touch it at all.

three) Brace Yourself

If, like me, you didn't bring your tripod with you and you even so want to have pictures in the dark, you can stretch the dominion of pollex (above) by a few stops by bracing yourself and/or the camera against a tree or wall or lamppost. Also controlling your breathing can help quite a bit too. Here'south a picture shot at a slow shutter speed using this technique.

Finally I just want to say that an inherent problem with a lot of today'southward smaller cameras, specially phone cameras, is that, considering they have no viewfinder, nosotros are obliged to hold them at arm'due south length to view the screen, frequently holding them simply with our fingertips. This makes them infinitely more difficult to hold still and makes them much more than prone to show the effects of photographic camera shake. So even more care needs to be taken to get a sharp picture. If you are taking a movie with a phone camera (if you really must!), try to rest it on something, a table or wall, to help keep it even so.
