 If you want to batch process some equally sized images with the same correction values (only possible if you shot them all from a tripod without moving the camera) you can simply add them to the project on '''Source Images''' tab.

 On '''Create Panorama''' tab page select '''Multi image TIFF''' for output. You get the images saved with the base name and a four digit number appended.

-Using a shift lens (provided you get one with a short enough [[focal length]]) this would have been shot with camera level and film or sensor parallel to the subject and the lens shifted diagonally. The respective parameters to simulate this in panotools are '''Yaw, Pitch''' and '''Roll'''.

 Sometimes you have to shoot in very tight spaces but would like to show the image in a frontal view.

 It is not often necessary to correct for a panned camera since we are used to horizontal perspective distortion. One use is to shoot a mirror without the camera beeing mirrored.
-If the camera was level to the horizon, one pair of [[horizontal control points]] is enough to correct for horizontal perspective distortion. Go to '''Control points''' tab and set one point to the left of something horizontal in your image in the left pane and one point at the rigth of the same horizontal structure in the rigth pane. This vertical structure must not go through or near the image center. Be sure to choose '''Horizontal line''' as control point type.
