This dialog box controls the parameters used by the Korrigiere Tonnenverformung / Correct barrel distortion command (Neues Bild / New image menu).  As you change the parameters, The Panorama Factory shows you the effect interactively within the preview rectangle.

Stärke / Amount — Enter the amount of correction.  Barrel and pincushion distortion are characterized by the percentage change in magnification from the center to the nearest edge of the image.  With barrel distortion, the magnification is smaller at the edges than at the center of the image, so you use small negative numbers (‑10% is a large correction) to correct barrel distortion.  With pincushion distortion, the magnification is larger at the edges than at the center of the image, so you use small positive numbers (10% is a large correction) to correct pincushion distortion.
