New page

As explained on the [[Hugin Photos tab#Geometric_.28Simple_and_Advanced_User_interface.29|Hugin Photos tab]], [[hugin]] uses a photo alignment scheme where it adjusts image orientation and lens settings of source photos
until the [[control points]] line-up. This process is called ''optimisation''. Normally you will use the [[Hugin Assistant tab]] where [[control points]] are automatically generated, or use the '''Feature matching''' option from the [[Hugin Photos tab]] to generate [[control points]].

You can '''manually''' create individual '''control points''' in the [[hugin Control Points tab|Control Points tab]], and you can ''manage'' them in both the [[Hugin Photos tab|Photos tab]] and [[hugin Control Points table|Control Points table]].

 Similarly, the translation parameters could be used to correct a wonky shot. However, they were meant for linear panoramas which expand to infinite distance at 180 degrees field of view, so you must make sure any images with non-zero translation (X, Y, or Z parameters) are in the middle of the panorama (y and p should all be around zero, and the field of view shouldn't be large enough to make them expand more than 180 degrees). This can be used to patch in the floor after you have removed the tripod that was obscuring it. You can take a shot of the floor where the tripod was at an angle (therefore you can avoid casting a shadow on the image in most cases). You can then optimise X,Y,Z on only this image. However, the floor must be flat for this to work, and this shot must be in the middle of the panorama. You can make down the middle by rotating the panorama on either of the previews.
