Does the no parallax point need to be discovered for ever scene?


(Mica) #1

I acquired a panorama tripod head and have been trying to figure out how to stitch a 360 single row panorama.

I had thought I’d done an adequate job of finding the no parallax point, but I can’t get a good stitch using hugin. The power lines in the background do not line up.

From what I’ve read, it seems you’d calculate the no parallax point once per lens/body combination. Is that correct?

That is correct. Unless you’re using a zoom lens, in which case the NPP (or LPP - Least Parallax Point) will drift.

The easy way to find the no parallax point is to stop down using DOF preview and look at where the iris appears to be.

Thanks! No zooms here, primes only. :slight_smile:

The first link on the panotools wiki has a good description of a couple of methods for finding it:
