|It is said that the visual field of human beings covers approximately up to 180 degrees in both horizontal and vertical way.
As regards 35mm camera, diagonal angle of view of 50mm lens is 47 degrees and even that of 15mm lens is no more than 111 degrees, and furthermore, as angle of view gets wider, subject gets smaller and overall view in the viewfinder gets distorted.
Only fish-eye lens has about as same angle of view which is 180 degrees as human sight. But, as those who use fish-eye lens know, that lens jams all the view in the viewfinder into the circle frame, which makes a picture unnaturally (at the same time, which is an attractive point of that lens, though).
|Like one of the inventors of photography, William H. F. TALBOT who made a photography by joining a series of two pictures taken by means of Kallo type way with one, Photographers had been seeking for the camera with which they could take a super wide-angle picture with natural perspective, that is to say a panoramic photography.
In 1844, a painter, Martense contrived Daguerreotype lens-rotating panoramic camera "Mega-Scope" which is now said to be one of the original panoramic camera.
Like I said in the previous sentence "one of the original...", several kinds of panoramic camera were invented. So, let's take a brief look at these structures for the next.
1. The lens unit moves and the film is fixed when the shutter is released.
2. The camera body itself rotates or the film is transported in order when the shutter is released.
There is also a minor type like the one whose lens is developed only for panoramic photography.
