    Correcting Perspective

    by Steve Lockyer » Sun Jul 26, 2009 1:37 pm

    Just wondering what is the easiest way to correct perspective in CS3? I have done some 6 shot panos of a building and they are a long way out as you can imagine.

    Any help, on or off topic would be awesome!!!!!!!!!

    CS3....... use the crop tool

    crop the whole image...... top of page tick the square PERSPECTIVE [only appears when crop tool is used] then move the corners as needed........

    What about the Lens Correction filter (Filters >> Distortion >> Lens Correction)?

    Will build websites for 'L' glass.

    My missus corrects my perspective with an appropriate look. Very effective too.

    That is the one I was looking for thanks Dale. Norm, I can't post this image as it's a paid shoot and the building has very distinguishing signage all over it :lol:

    Craig, very funny! :D

    I think the main problem was shooting 17mm wide over about 150 meter frontage and panning in one spot. Maybe I should have walked 10m or so per frame and stitched them together. After the job is done I should be able to post an image or two. I have a big scissor lift for next weekend to shoot the same building so I need to get my pano's sorted by then :D

    If it was me, I would be using a longer focal length, and incorporating more images, to help overcome lens distortion issues. As a bonus, the resulting 'merged' image should also have more pixels in it too.
    I've had a few issues with wide angle stitched panos in the past...
