Step A -- Stitch the central row

In this step, you stitch the central row of images into a 360 degree panorama.  This central row is used as the starting point for the full sphere panorama.  It establishes the focal length and the horizontal axis of the panorama.

  1. Start a new project and immediately Cancel the Wizard.

  2. Use the Import images... command (File menu) to import the images images for all rows into the project file and make sure they are arranged left to right in each row, one row after the other.  Here are the images we'll be using in this example:

  3. Select the thumbnails in the central row (tilt angle zero) row and choose the Stitch with the Wizard command (New image menu).

  4. Choose Semi-automatic photo stitching on Wizard 2/9.

  5. Select Automatically detect focal length and Correct barrel distortion on Wizard 3/9.

  6. I recommend not selecting any checkboxes on Wizard 4/9.

    • You should disable automatic fine tuning of the image alignment because stitching is a lengthy process and may require some back-and-forth in the program. Fine tuning in the Wizard will slow things down. You can apply the Fine tune command (Image menu) after stitching is finished, so itís often best to postpone this step until everything else is just right.

    • If you have used your camera in manual exposure mode, exposure matching and exposure correction should be unnecessary.  If you decide later you want to try these options after you're done stitching, you can use the Blending properties dialog box (Tools menu) to change the settings.

    • Sharpening is best applied to the final image, not to each stitched row individually. so we disable it for the individual rows.

  7. Select 360 degree panorama and Spherical projection on Wizard 5/9.

  8. Place stitching points on Wizard 6/9 to stitch the first row of the panorama.  I recommend this procedure for plsacing stitching points:

    • Place stitching points on one image pair. I recommend using distant points and/or points all in the same plane.

    • After placing 5 points, you should get a dot in the Images list.

    • Once you have the image dot, go back to each stitching point in turn and examine them at large zoom scale (400% or 500%).  Adjust the stitching points so that they match well on the two images.

    • It is probably sufficient to place stitching points on just one image pair because you are using Semi-automatic photo stitching.

  9. Advance to Wizard 7/9.

    Examine the preview image to be sure the stitch is accurate.  If it is not accurate, return to Wizard 6/9 to adjust stitching points or add new stitching points to other image pairs.

  10. Advance to Wizard 8/9 and select Prepare for internet display and Maximum size.

  11. Advance to Wizard 9/9 to complete the stitch and click Done to exit the Wizard.

  12. At this point, you should see a stitched and cropped thumbnail in the upper pane and the cropped image in the lower pane.

Advance to Step B -- Stitch the upper row
