If your tile images contain a certain background shading, you can correct this if you have acquired a reference image for the shading correction. This image has to be opened in the Center Screen Area.

  1. Select in the tile image for the stitching in the Input tool as first input.
  2. In the Parameters tool select the New Output button.
  3. This will keep the original image and create a new output image.
  4. Activate the Correct Shading checkbox.
  5. Select the Reference entry from the dropdown list.
  6. This will let you select your reference image which is opened in Center Screen Area.

  7. If you do not have any image available for the shading correction, you alternatively can calculate a background image from the input image via the second selection Automatic under Correct Shading. This will only work, if your input image does not include large dark regions.

  8. Now as a second input image select the reference image for the shading correction in the Input tool.
  9. Click on the Apply button to start the processing.
  1. As a result you will get a stitched panorama image without any shading influences. The next chapter will show you how to get rid of the edges which are still visible between the tiles.
