In the previous example the image was corrected to maintain parallel lines in rendering the final output.

Speaking of control lines, the software can also be used to generate lens correction parameters as well. The view on the right is possible without modification using a view camera, but can be approximated using a few extra control lines in the panorama software. This produces an “architectural view” (really axonometric, or really really planometric). From the same panorama, the right image was generated, but in this case the vertical lines of the image were identified in the software. On the left is the rectilinear projection after correcting for lens distortions. The image above is stitched from 3 images. This allows all of the parallel lines to remain parallel in an image: View cameras have the option of shifting the lens up vertically to include the top of a building without having to tilt the film plane. Doing so will lead to converging parallel lines. Shooting a building from ground level for instance will often require the photographer to pan the view up in order to include the top of the building. This comes in particularly handy for shooting architectural subjects where you want to maintain parallel lines in the image. One of the really great capabilities of having the lens plane adjustable relative to the film plane is that the image can be shifted while maintaining orthogonality with the subject. The file contains the averaged image as layer 0 and all input images as additional layers with the mask as described above.This effect is produced in view cameras by modifying the front plane with the lens relative to the film plane on the back plate. Or with the option -multi-layer-output you can output a layered TIFF with the name specified with -output. Set the suffix with -mask-suffix=STRING (default is _mask). You can output a separate mask image for each input image. The sigma parameter for this step can be changed with -mask-sigma=NUMBER (default is 2). If it is in the mentioned range the pixel is masked out. Then each pixel in each image is checked: if the value of this pixel differs more then mask sigma * standard deviation from the mean/median, this pixel is made visible. In this case the stacked image is calculated first. For tiff files valid values are: PACKBITS, DEFLATE, LZWīeside the stacked output hugin_stacker can also mask the input images (available only for stacking modes median|winsor|clip).For jpeg files use values between 0 and 100.-compression=value: Set the compression of the output files.-output=FILE: Set the filename for the output file (if not given final.tif is used).

There are several stack modes (switch -mode) available: Hugin_stacker stacks overlapping images to a single image.
