Hello folks, I have been using Johns tutorial (Thanks again) on adding
a nadir to an image. It has helped me a lot and the idea of using 2
shots straight down at 45 degrees apart has been great. It leaves a
very small hole to fill. The question I have today is on the zenith.
Would it be wise to use the same technique, 2 straight up 45 degees
apart ? I am having problems with power lines not aligning when adding
a handheld zenith shot. Most of the Zenith is perfect through control
points but the matching of wires, in mid air, are almost always off. I
was using photoshop to distort a zenith image and then patch after
placing the zenith in the center as a circle. I would like to use the
photoshop fill as little as possible. Any help is appreciated on
adding the zenith. Lens is a 8mm sam yang on a D7000. Usual is 5 shots
around @ 0 degrees, 2 down @ 90 degrees (each 45 degrees apart), 2
hand held, zenith and nadir. Thanks in advance. Any feedback is
appreciated.
