A
B
Banding Visible steps in smooth gradients. Early versions of Panorama Tools software could introduce obvious banding, for example during radial luminance correction as discussed by John Houghton. This problem is largely corrected in current versions of the software.
C
Cylindrical Projection A projection capable of mapping 360 degrees horizontally by roughly 120 degrees vertically with acceptable distortion. See Cylindrical Projection for more information.
D
E
Entrance Pupil The special point that you have to rotate your camera around, to avoid parallax errors. Commonly referred to as the Nodal Point, which see for more information.
Equirectangular Projection A projection capable of mapping the entire sphere to a rectangle with 2:1 aspect ratio. See Equirectangular Projection for more information.

Pitch Angle up-and-down (above and below horizon). See also "Roll" and "Yaw".

Rectilinear Projection A projection in which every straight line in the world stays straight in the image. See Rectilinear Projection for more information.
