I'm really comfortable making corrections with horizontal lines. Based on Torsten's tutorial I translated to the new version of Hugin and where the image jumps after you make a control point. In a horizontal image you just know that you can click on both sides of the image just at the inside edges and continue. That's where he says "you can just turn your brain off" in the tutorial video. In an image where the subject is vertical or angled lines, I'm not sure how that would work. The corrections I get from multiple horizontal lines seem to work fine for everything, but I want to understand how to use vertical or oblique lines.
Torsten, I emailed you a couple times. I'm looking to contribute by making corrections for user submissions. Thanks everyone for the assistance.
