Conversion form Cubic to Sph~ No -Good
The location was a open plot of land. I took 4 images landscape ( not in potrait mode)
Did not take Nadir & Zenith .
I made a panorama (spherical) using easypano (4/Nikon D80+Sigma8mm/ Smartblend).
Then blending was good, no vignette arcs in the sky or on the ground, except for big black hole in sky & on the land.
To touch up Nadir & Zenith I converted it to panorama (cube) using easypano
I saved the file as TIF.
Then i did the touch up in PS using heal tool/ copy past and saved as TIF
Then i loaded the images back to easypano to make into spherical.
When the conversion took place there were light vignette of ARC on the sky and on the ground.
What could have possible gone wrong??? Is there a bug in software??
