Stitching when shadows are present

[prateek prasanna]

Hi all,

Recently, in the images I have taken, the shadow of the camera appears in each shot. This results in pretty bad stitching. Any suggestions as to how to improve stitching in presence of shadows?

Thanks,

The stitching ought to be very good, albeit with the shadows of camera
and tripod faithfully recorded. Additional shots should be taken with
the tripod moved away to capture the areas formerly occupied by the
shadows and tripod. These shots are then included in the project and
aligned with viewpoint correction (provided you have the Pro version
of PTGui). Masks are applied to remove the tripod and shadows and the
net blended result is a complete panorama without shadows. It's best
to mask away the shadows and tripod/panorama head from all the input
images before control points are generated so that they cannot
compromise the image alignment process.

Alternatively, it may well be practical to simply edit the stitched
image in Photoshop to remove the shadows using cloning tools and
content aware fill. To do this it's more convenient to work on
rectilinear views extracted from the equirectangular image - e.g. by
generating 6 cube faces, which can be edited and then reassembled to
form the final panorama image.

Use Advanced interface. On Control Points tab delete all control points
in and around the shadow. Use Shift+drag to select an area of control
points.
