Estimating a lens
1 Click Estimate in the Edit Lenses window.
The Lens Estimator window opens. The first two images of your series appear. If you want to
use another pair of images for the estimation, click Previous or Next until you reach the pair
you want to use. You should choose images that have detail, but do not contain repeating
patterns. The pictures of the Company Store below have enough detail to be aligned
properly. A poor example would be two images of window blinds. The blinds consist of a
repeating pattern of horizontal slats, so the estimator could align the wrong slats.
2 Enter estimated values for the beginning and end vertical angle of view; then enter a step
value in the Step box.
The Panorama Stitcher uses the values you enter to establish a search range. Within that
range, it searches for similar areas between the two images. The beginning vertical angle of
view is the starting value. For each search, the Lens Estimator advances the number of
degrees specified in the Step box.
3 Click Estimate.
A progress window appears. When the calculation is complete, the Lens Estimator window
closes. The estimated vertical angle of view appears in the Edit Lenses window.
4 Click Done in the Edit Lenses window.
The Edit Lenses window closes. Your lens appears as a choice in the Lens pop-up menu.
