I am an engineer with a great interest in most aspects of photography and generally I use a Sony Full Frame A99V SLT camera on a Manfrotto stand with a <a href='http://jam.nodalninja.com/affiliates/jrox.php?id=27_1_tlid_1_ut' target='_blank'>Nodal Ninja</a> 4 panoramic head for my panoramic photographs. I have a photo website at http://www.pbase.com/junglegeorge/ with some 23,714 phots and growing. I am new to spherical panoramas and working towards mastering the technique. I find the sky zenith the hardest to get right.
