Originally posted by SirTomster I have found that if I am shooting a distant scene all is well. Introduce something nearby and everything goes out the window.
Below is the image I was trying to take. I can assure you that the train tracks do not go in that direction. I could have done some Warping in PS to fix but that was quite hard to keep the tracks straight. I did not try in ICE or PTGui though.
Instead, I figured I could just get my rig setup where I reduce the cause for this issue. It can only improve my shots. 1 L Bracket, 1 Nodal Slide, 1 Leveling Base and I hope it work out better. But I wonder if I will want to get a RRS Panorama setup to take a multi-row panorama. Or a knockoff that is a LOT cheaper.
This is a very slippery slope and I am already down the rabbit hole. I am doomed.
Warp doesn't look like a solution; barrel distortion, OTOH, might.
However, the issue is better resolved at the root, by choosing the right projection from the start, as @mee suggested.
Edit: a coarse example, which incidentally demonstrates that the kind of deformation is not barrel proper, but rather moustache distortion.
Using a piece of software that allows you to select the kind of projection
before stitching will spare you from this massive loss of quality, and get things "straight" the first time around.
