Stitching Process - 1

 

 

My stitching process depends entirely on the number of "nadir" images that was possible to shoot a particular location. 

 

Two nadir shots if I'm unable to shoot the ground for any reason(s).

 

Three nadir shots; two with the VR head and one hand held; if lighting is good enough for a hand held.

 

One hand held nadir shot if the lighting is good.

 

One nadir shot on the tripod. (Under Nadir Shooting Techniques)

 

I will explain them all...

 

Two nadir shots...

Take six pan shots at every 60°, one upward (zenith), and two downward shots (nadir).

 

 

 

Photoshop

 

In Photoshop, layer the two nadirs and add a layer mask.

 

Understand how to work with layers here.

 

 

PTGUI

 

In PTGUI, add the edited nadir, generate control points and create panorama.

PANO2QTVR

 

 

In PANO2QTVR, convert the stitched image (equirectangular) to a cubical projection.

Photoshop

 

In Photoshop, there are various ways of filling in the hole.  For this particular nadir, I used the vanishing point tool.

 

Other tools to use: Clone tool.

 

Read up on this technique here.

 

Once finished editing, in PANO2QTVR, re-convert the six cubical images back to an equirectangular image.
