Edit The Image : How To Convert Source Images Into Panoramas
Did you know it is no longer necessary to edit your panoramas to create Virtual Tours?
The editing of a panorama is the transformation of the original photographs into a panoramic image that will serve as the basis for the creation of interactive Virtual Tour.
While editing, in general, is a necessary step in the creation of the Virtual Tour, there are cases in which these can be created directly out of the source image as it comes out of the camera: these are the single shot panoramas, namely 360 degree donut shots and simple fisheye shots.
Sequences of photographs taken partially overlapping by rotating a camera around an axis, instead, necessarily require this step: the images are combined with each other to form a single panoramic image, which may or may not Span 360 degree.
Depending on the equipment and the system used to photograph, the resulting picture may be of different types :
The cylindrical panoramas are those that when navigated interactively show two empty spaces, one in the top of the sphere (zenith), another one at the bottom (nadir). They are defined as the projection of a panoramic image on the inner wall of a virtual cylinder. Not spanning the high and low ends, these panoramas cover always less than 180 vertical degree. They can come from the stitching of multiple photographs as well as from the remapping of a single image, for example, a 360 degree donut shot.
The spherical panoramas, instead, are the projection of a complete image of 360 x 180 degree in the inner wall of a virtual sphere. These are necessarily are photographed in several shots and therefore it is inevitable some editing job to combine them.
A cylindrical panorama can not become spherical because the sphere have parts that are not photographed. However, it is a common resource to cover the empty sectors with other images such as companies's or photographer's logos. It is an usual resource to try to photograph the top of the sphere (zenith) to concentrate all the empty area in the opposite sector (nadir). With the help of a nodal rotator this can be achieved easily.
A special case of combination of images is the combination of fisheye shots. Since each shot covers over 180 degree not only in width but also on high, creating a panorama all around the horizon is equivalent to creating a complete sphere. Just two fisheye shots, if they are properly aligned, are enough to make a complete sphere, although some equipment will be visible in the final product. In these cases it is usual to edit this area covering it with another image, or stopping the navigation in that direction.
Finally partial panoramas are those that do not cover the entire horizon in its horizontal expansion. The simple Fisheye Shots are a specific type of partial panorama, although most of these come from the combination of images aligned horizontally. Ultimately, almost any image wider than high can be considered a partial panorama.
