There is a center parameter in lensfun, it seems to work OK to just create a
version of the lens that I had previously calibrated the distortion parameters
then add a y value.
Hugin lens calibration will also calculate the parameter eg "d", however you
have to give it a starting point that is
Yeah, I get the sense that hugin et al comes from the school of thought that
you should digitally shift the images.
Though the answers in thread don't really make sense, because the lens
distortion model is still circular, it's not like it was tilted.
I wonder if tca_correct can deal with it.
