Hugin Photos tab
The Photos tab is a combination of the "old" Images tab and the "old" Camera and Lens tab as being used in Hugin versions untill 2012.0.0.
The Photos tab is used to:
- Manage the images in a hugin project.
- Edit the positions of the images in the final panorama.
- Edit the lens settings.
Multi-selection can be used to change the parameters for multiple images.
User interface modes
The User interface modes, being Simple, Advanced and Expert determine the layout and (number of) options in this tab.
The Display radio buttons on the right side determine the layout and what is displayed in the images table. What is displayed in the table, e.g. the number and kind of columns, per Display option is again user interface mode dependent. For example: In the Display option General the column Stack no. in the images table (see above (enlarged) screen capture) is only visible (and available) in Advanced and Expert mode.
On the right side of the screen you will find the Group by: drop down box with immediately above it the label showing in which user interface mode the screen is currently being used. The available options are displayed in the table below.
Simple | Advanced | Expert |
---|---|---|
None | None | None |

This tab contains a "Context menu", sometimes better known as a "right-click menu" which is accessible in the images table.
There are three possibilities:
- A "right-click" in the table without any image(s) selected
- A "right-click" in the table with one image selected
- A "right-click" in the table with multiple images selected.
No image selected | One image selected | Multiple images selected |

Adding images
Images can either be added with:
- the button Add individual images...
- via the context menu (Add individual images... and Add time series of images...)
- via drag and drop.
Add time series of images... adds all images with a similar file modification time as the selected image; if the the project is empty then a file dialogue opens to allow you to pick this initial file.
Control points
Individual control points can be created and edited in the Hugin Control Points tab, here in the Photos tab they can be manipulated together.
Automatic creation of control points can be done by pressing the Create control Points button (if you select just some images, then control points will only be found for those selected). with the dropdown selector in front of the Create control Points button, you select which control point generator (feature matcher) to use for detecting the control points and adding them to the project. These control point generators (feature matchers) need to be configured in Preferences->Control Point Detectors. Hugin comes standard with cpfind configured for a few situations. The Hugin Preferences can be used to set further options and to add new tools to the list or another instance of the same Control Point Detector with other settings (like for rectilinear images or for (full) frame fisheye for example.
The Remove control Points option from the context menu option Control Points does exactly what its name suggests, it removes control points between the selected images, or all control points if no image is selected.
Image Position
In the Image Position section, the orientation of the selected images in the final panorama can be specified by yaw, pitch and roll angle (in degrees); and the X, Y, and Z translation parameters. The Reset button will reset all angles and translations to zero. This is useful if the optimizer could not determine the image orientation entirely correct and got stuck with a suboptimal result. It is possible to select multiple images at the same time. Changes in orientation will be applied to all selected images.
Note that it is also possible to reset Image Orientation along with other parameters using the Reset... button on the Hugin Camera and Lens tab.
Select Anchor this image for position to indicate that a particular image shouldn't move when optimising with the hugin Optimizer tab. Only one image can be the anchor, and by default this is the first image in the project.
Exposure
Selecting Anchor this image for exposure will indicate that a particular image should be used as an unchanging reference anchor when optimising Exposure or White balance in the hugin Exposure tab. Usually this should be the image with the least under or over-exposure or the image with the most typical White balance.
Stacks
Image orientation can be linked between a group of images if they are already aligned. For example, if they form a bracketed (exposure) set shot on a sturdy tripod. To do this, select all the images in the stack, and press the New stack button. You can also move images into an existing stack without selecting all the other images in the stack: press Change stack... and enter the stack number you want the selected images to join. The stack number of each image is given in the table.
If your images form approximately aligned stacks, you can create stacks as usual, select all the images and then uncheck Link by the image position. Approximately aligned stacks are common when you shoot bracketed sets handheld, or in windy conditions with a light tripod. Hugin will remember that the images form a stack, but does not force the image orientation and translation to be the same across the stack. This is useful for specifying stacks when you have a Panorama with Stacks control point detector configuration before control point generation. You do not have to manually mark approximately aligned stacks in other circumstances, however.
