Step H -- Rotate the fully stitched image 90 degrees counter-clockwise

At this point each image has a horizontal angular resolution of about 10 pixels per degree because we resized each 380 degree image to 3800 pixels.

In this step, we rotate the fully stitched image back to its correct orientation.

NOTE: It is probably best to make manual adjustments to the stitched row images and the fully stitched image before starting this step.  If you see ghosts (faint double images), you can often correct them using the Fine tune command (Image menu) and/or with manual fine tuning.  For more information, refer to the section "Fine tuning the image alignment" in Chapter 6 of the online help, "Correcting stitching problems".  Sometimes ghost images cannot be eliminated with fine tuning, for example if an object (e.g. person or car) moved between the times you made two photographs.  You can sometimes remove these ghosts by adjusting the boundaries of the blending region.  For more information, refer to the section Adjust blending region boundaries in Chapter 4 of the online help, "Using the Classic interface, step by step".

  1. Double-click thumbnail of the fully stitched image to make it the current image shown in the lower pane.

    NOTE: You'll also see a cropped thumbnail in the upper pane, but we don't want to use this image.  The Wizard always crops the stitched image, but sometimes the cropping can introduce a small amount of image rotation.  This is usually the right thing in normal stitching (and, in fact, for the initial row stitches) because it corrects for small rotations that are left over after stitching.  However, in this multi-row procedure, we want to avoid any new rotation after the initial row stitches.

    So we double-click the stitched thumbnail.  The stitched image will display in the lower pane, with outlines superimposed on the image to indicate the image overlap regions.

  2. Choose the Rotate command (New image menu).

  3. Under Image rotation, enter 90 degrees and select Counter clockwise.

  4. Select Fit rotated image.

  5. Click OK.  This adds the rotated thumbnail to the upper pane and shows it in the lower pane.

Advance to Step I -- Crop the rotated image to exactly 360 degrees

Back to Step G -- Stitch the rotated rows together
