Automatic detection of brightness
falloff does not always work properly
Automatic detection of brightness falloff sometimes gives poor results,
especially when the camera is tilted or rotated a large amount..
When the automatic detection results in a
poor correction of brightness falloff, you can adjust the falloff
correction manually. You'll have to do this after stitching is
completed and after you exit the Wizard.
For step by step instructions, read the
sections Opening an overlap region and Correcting brightness
falloff on the help page
Adjusting exposure matching and brightness falloff.
