Re: [Rollei] Panorama head question

[Rich Lahrson <tripspud >]

Hi!

     I'm in favor of presenting the Rollei pano images printed each
full frame and maybe tightly separated by a black line of a sixteenth
of an inch or so.  The eye can see it but it's not a bother.  Trying to
line up camera lens images in pano is pitb, been there.  Rich
