  • Struggling with getting a building straight

    I took the attached panorama in Athens just recently ( I wanted to photograph this old library before the looters got to it! ).

    Anyway I can't obtain an architecturally straight building. I've tried in CS5 and PTgui the latter software has great options to straighten the image but not enough for this one.

    I took the image as a multi row, a friend thinks it's possible that I didn't take a row of images exactly level with the ground. In other words I did a row for the sky facing up, a row for the ground facing down but the one which should have been at zero degrees was perhaps out a bit.

    So my question is:
    Is it essential when taking a multi row pano like this to take a row at exactly zero degrees?

    Or perhaps someone can offer another opinion.


    Many thanks

    No, it is not necessary to take a row of images exactly level with the ground. Indeed it is not actually nessary to take the shots in rows at all, though that's the usual way of course. You can easily level the panorama accurately during the stitching using t1 (vertical line ) control points. See http://www.johnhpanos.com/levtut.htm - it takes less than a minute.

      John,

      Thank you for what appears to be an excellent solution to my problem. I'm tied up with work right now but will get back to this in the morning. Once again thank you.
