Description

The present invention relates to a device for levelling a support, particularly a support for cameras and cinecameras.
More specifically, the invention relates to a device of the above kind permitting obtaining levelling of the support, particularly for cameras used to take those photos usually known as “panoramic photos”.
During recent years, panoramic photos have had a remarkable evolution, particularly with development of digital photos.
Substantially, it is a photographic technique based on taking sequential photos, moving camera about a vertical axis, so as to place all images according a sequence along 360° rotation.
Obviously, in order to professionally realise this kind of photo it is necessary placing camera on a tripod, and thus obtaining perfect levelling of camera with respect to horizon, so as to have a perfect correspondence of side by side photos, thus being possible obtaining a perfect panoramic image.
Technical conditions exist to take a perfect panoramic photo that must be absolutely respected, among which precision of levelling and matching of focal point with rotation the head.
In order to obtain the levelling precision, devices are available on the market, to be placed on the camera tripod, in order to obtain levelling precision, both on the horizontal plane, or rotation plane, and on the vertical plane, or plane perpendicular to the rotation plane.
At present, it is not available on the market a device permitting obtaining both adjustments in a simple and functional way.
Object of the present invention is therefore that of providing a device for levelling a support, particularly for cameras for panoramic photos, permitting obtaining levelling both on the horizontal and on the vertical plane, and that further permits rotating camera on tripod to take the panoramic photo.
