Of course the final calculation does it right. What I mean is that there is only one parameter in the pto, and that's the horizontal field of view. Of course, if you have the pixel dimensions you can arrive at a correct calculation, but if you mix landscape and portrait shots of the same lens in a panorama, you have images with two different hfov values. That's why Jeffrey Matin says: > why is it HFOV and not FOV "in the narrow image dimension" ? wouldn't this > be better? And, having thought about it some more, I agree with him for two reasons: - with true fisheye images, the diagonal isn't inside the image. It may even be silly to calculate a dfov for a fisheye - it might be nominally more than 360 degrees. The narrow edge will be about 180 degrees in a fisheye, so no problem. - the (current) lens correction polynomial is, if I'm not mistaken, based on the small side of the image as well (taking half the diameter there as unit radius), so hugin already uses this standard.

I'd say - not really a problem, but if the first six are portrait and the up shot landscape, if it's a manual lens (like my Samyang) I have to tell hugin every time it's the same, even if the image dimensions are the same to the other shots. More a nuisance. I have to have two lens.ini files handy, or go through the dialog every time of 'do I want to accept the parameters even though the image dimensions are different'.
