A little publication abour panoramic 360º photography thecnics and virtual tour productions.
Citation preview
What is Panoramic Photography? Is a techinique of photography using especialized equipment and / or software to create images with:. 2:1 aspect ratio or more. Field of View elongated then a normal picture.
Panoramic Images
Panorama of Along the River During Qingming Festival, an 18th century remake of the 12th century original
Panorama
360 degrees panoramic painting of Edinburgh – Robert Barker 1796
San Francisco from Rincon Hill. Daguerreotypes by Martin Behrmanx c.1851
Panorama
Downtown Philadelphia 1913
View from the top of Lookout Mountain, Tennessee, Albumen prints, February, 1864, by George N. Barnard
CycloramaCyclorama is a panoramic image on the inside of a cylindrical building to create an illusion for the viewer, surronded by the entire picture, feel as if they standing in the middle of a famous place or event.

A 360 view of Husband Hill Summit – Mars 2005
Leme Panoramic Camera
Brazilian Photographer Sebastião Carvalho Leme (1918-2007) invented the first 360 degrees photo in a single negative.This camera was monted in a small tomato purée can with a manual rotation lens and a internal device (his principal invention) to fix the film.
360 degree view of Marília City Council.

Parallax and No Parallax Point
Parallax is the apparent shifting of a foreground object relative to a background object when viewed at different angles or perspectives. With panoramic photography, multi-shot images create an issues know as parallax.
This is because each image shot is actually different from the one before it due to the minor shifting of objects in the field of view. The foreground objects will tend to shift from the back ground objects if the camera is rotated outside the no parallax point, the entrance pupil or nodal point of the lens.

The foreground objects will tend to shift from the back ground objects if the camera is rotated outside the no parallax point, the entrance pupil or nodal point of the lens.
No Parallax Point (also called Nodal Point) is the entrance pupil, a floating point located inside the lens at the point where the light refracts or reverses itself, at before continuing to the image sensor or film plane.
The geometric location of the entrance pupil is the vertex of the camera's angle of view being different on each lens and changes at different focal lengths.
Depending on the lens design, the entrance pupil location on the optical axis may be behind, within or in front of the lens system.
Using a special head and adjusting it properly so it rotates about the “entrance pupil” or nodal point of a lens will eliminate virtually any parallax.

No Parallax Point = Nodal Point or Entrance Pupil Nodal Point – IS NOT correctly but the most Common term.
No Parallax Point – Nodal PointHow to Find?
● Use a tripod with Panoramic (Spherical) Head;● Decide which focal lengths of lens to calibrate for;
No Parallax Point – Nodal PointHow to Find?
● Use a tripod with Panoramic (Spherical) Head;● Decide which focal lengths of lens to calibrate for;● Set up your camera as far back on the upper rail as
possible, pointing the lens towards the horizon and parallel with the ground;
No Parallax Point – Nodal PointHow to Find?
● Use a tripod with Panoramic (Spherical) Head;● Decide which focal lengths of lens to calibrate for;● Set up your camera as far back on the upper rail as
possible, pointing the lens towards the horizon and parallel with the ground;
● Position in front of the camera two objects – one nearer than the other, one about 6 feet and the other about 10 feet, creating two vertical lines working as only one line, positioning one behind the other;
No Parallax Point – Nodal PointHow to Find?
● With the camera in portrait mode and
looking inside the viewfinder, or LCD
screen, position the camera so the
two objects are towards the left side
of the frame.● Note the exact position of the two
objects. Ideally place the objects so
They are not directly behind each
other.
No Parallax Point – Nodal PointHow to Find?
● Rotate the camera so the two objects
are now in the right side of the frame.● Go back and forth a few times and
watch to see if the apparent distance
between the objects changes.● If the distance changes, even slightly
then you have parallax
No Parallax Point – Nodal PointHow to Find?
● Loose your camera mounting knob.
● Move the camera slightly forward (2mm)
● Repeat the steps until there is no more apparent movement between objects.
