I followed the argumentation on nodal points etc when shooting panoramas.
Somebody mentioned that actually it is not THAT important to use a specialized panorama head, or at least I did understand that.
I tried it myself.
Now first I used my ball head with the camera in portrait position. Keeping the head horizontal was no problem but when I tilted it upwards keeping the camera vertical was not easy, the ball is free in all directions. I had only horizontal levels.
Then I tried with a movie pano head.
It allows both movements in the horizontal and vertical planes.
But the camera is positioned only horizontally.
Now: For a given panorama I need the same number of photos, be it H or V.
Is there any disadvantage using this or that option? I mean positioning the camera H or V?
The results of my experiment with the movie head were satisfactory. No noticeable parallax errors, at least for what I do.
Any opinions?
