Although there are many other uses, hugin is primarily a tool for assembling multiple photos and creating a 'seamless' result.

This process is completely automatic if you use the hugin Assistant tab, but hugin also allows full manual control of every stage. So hugin divides up the various stages and presents them as tabs in the main window. These tabs are roughly in the order of panorama creation from left to right, though in practice fine-tuning a project can involve some jumping around between tabs.

This is a quick overview of this tab system, it isn't a step by step tutorial, you can find these on the hugin website.


The hugin Assistant tab is the fully automatic part of hugin, here you can load images, align them and stitch them into a panorama without having to use any of the other tabs.

Alternatively, you can use this Assistant as the first step in creating a project that will involve the use some or all of the other tabs:


In the hugin Images tab you can add or remove photos to and from your project. The table in the middle also shows the positions in the final scene for each the images, these positions are actually angles for roll, pitch and yaw.

Although you could enter these positions manually here, you are more likely to create control points in the hugin Control Points tab and then use the optimiser in the hugin Optimizer tab to position your images for you.

Camera and Lens

Photos have properties that need to be known in order to assemble them seamlessly, notably geometric properties such as field of view or barrel distortion, plus photometric properties such as vignetting or exposure.

Again, although you could enter parameters for these properties here in the hugin Camera and Lens tab; hugin can estimate the field of view from data stored in the photo by the camera, it can also use the optimisers in the hugin Optimizer tab to calculate the geometric distortion, and in the hugin Exposure tab to calculate photometric corrections.


Often photos contain parts that you don't want to be used. Typically fisheye Projection images have a circular area in the middle with a useless black area outside. Scanned images have edges that need to be cropped away.

The hugin Crop tab allows you to apply simple masks to ignore these areas from your photos.

Control Points









TODO describe menus


  • New, discard the current project and start a new empty project.
  • Open an existing hugin, PTGUI, PTAssembler, autopano or autopano-sift project file.
  • Save the current project as a hugin pto file.
  • Save as a pto file with a different name.
  • Write PTStitcher script, saves a simplified project file suitable for batch stitching with PTStitcher, nona or PTmender. Note that nona can stitch a hugin project file directly, so this step is unnecessary when using nona.
  • Apply Template, assigns parameters from an existing pto project to the current set of photos. Only position and lens parameters are transferred, control points are ignored.
  • Quit hugin.


  • Undo, undoes the most recent change to the current project.
  • Redo, redoes an undo.
  • Optimize, re-optimises the current project. This has exactly the same effect as clicking Optimize Now! in the hugin Optimizer tab.
  • Add Image to the current project.
