# Hugin Images tab

The Images tab is used to manage the images in a hugin project. Additionally the positions of the images in the final panorama can be edited here.

# Adding images

Images can either be added with the Add individual images... and Add time series of images... button or 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 images tab they can be manipulated together.

Automatic creation of control points can be done by pressing the Create Ctrl Points button (if you select just some images, then control points will only be found for those selected). hugin will then launch autopano or autopano-sift and add the detected control points to the project. The Hugin Preferences determine which of these autopano programs should be used and set further autopano options. Remove Points does exactly what its name suggests, it removes control points between the selected images, or all control points if no image is selected.

Often a project has many control points attached to clouds in the sky, this is usually unwanted as clouds move between photos. Clicking Run Celeste will attempt to identify 'sky' control points using the celeste tool and delete them.

# Image orientation

In the Image Orientation section, the position of the selected images in the final panorama can be specified by yaw, pitch and roll angle (in degrees). The Reset button will reset all angles to zero. This is useful if the optimizer could not determine the image orientation well 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

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.
