Well that's a pretty sweet deal. 2008/9/11 Paul Stenquist [EMAIL PROTECTED]: I can't use a fisheye. The company that produces these virtual tours has very specific guidelines. I have to shoot vertical with a 17mm rectilinear lens and 30% overlap. (I'll use the DA* 16-50 or the DA 12-24.)

I applied for a gig shooting virtual reality tours of houses. The job should generate about ten assignments a month. To get a shot at it, I had to say I had a panorama head. Shortly after sending an e-mail application I received a call asking me to shoot a test by Friday. So I had to order

Does the new geared pano head have a bubble level to assist in finding the rotation center? If so, the manual will doubtless have instructions for use. Jack --- On Wed, 9/10/08, Paul Stenquist [EMAIL PROTECTED] wrote: From: Paul Stenquist [EMAIL PROTECTED] Subject: virtual reality panoramas

Paul, You really need Dave Savage to chime in here. He's done some fine panos. My experience is limited to 3 shots with the 31mm strung together. I just guessed that the nodal point was somewhere inside the glass. Regards, Bob S. On Wed, Sep 10, 2008 at 4:45 PM, Paul Stenquist [EMAIL PROTECTED]

Hello Paul, I did some Virtual Tour work a few years back. I finally ended up getting one of those special mirror lens attachments that shoot 360 degrees. There is special software that changes the circular image to something usable by the tour software. I even bought all the tour software and
