Panorama

Here you can set the output Projection of your project, there are lots to choose from, each with different advantages and disadvantages:

• Rectilinear, this is the same projection as a photo taken with a 'normal' camera and lens. Use this if you are just stitching a handful of photographs together with a narrow Field of View or correcting perspective in a single shot.
• Panorama, actually a simple Cylindrical Projection as used by traditional rotating panoramic cameras. A good projection for printing a 360 degree panorama, though you may prefer Mercator Projection.
• Equirectangular, the all purpose format for representing an entire spherical scene. It covers 360 degrees horizontally as well as the zenith and nadir.
• Fisheye, the same projection as a photo taken with a fisheye lens. Better for representing a wide Field of View than rectilinear, but in many cases Stereographic Projection gives less distortion than simple fisheye.
• Stereographic, a conformal fisheye image. Objects in a stereographic image keep the same shape and show less distortion than simple fisheye.
• Mercator, a conformal cylindrical image. A good projection for printing a 360 degree panorama.
• Trans Mercator, a mercator image rotated 90 degrees, suitable for displaying tall or overhead objects.
• Sinusoidal, an equal area projection of an entire spherical scene.
• Lambert Equal Area Conical
• Lambert Equal Area Azimuthal
• Albers Equal Area Conic
• Miller Cylindrical

Field of View

This is the horizontal and vertical angle of view of the output image, clicking Calculate Field of View will shrink or enlarge the field of view of the output to fit the arrangement of the input images - The Fit button in the Hugin Preview window does the same thing.

Note that some Projections have a limited field of view, notably:

• Rectilinear has to be less than 180 degrees both vertically and horizontally.
• Panoramic (cylindrical) has to be less than 180 degrees vertically.
• Stereographic has to be less than 360 degrees both vertically and horizontally.
• Mercator has to be less than 180 degrees vertically.
• Transverse Mercator has to be less than 180 degrees horizontally.
