Keystone correction

Discussion in 'Digital Cameras' started by Jeffrey Kaplan, Sep 1, 2006.

  1. I'm finding that I'm taking pictures that need keystone corrections
    (album covers as I convert my LPs to CD). One of my digital cameras
    can do keystone corrections, but it doesn't always detect the correct
    edges which leads to distorted images. So I'm wondering what, if any,
    photo editors can do this on my computer (WinXP Pro).

    I currently have ACDSee 8 and an older version of Paint Shop Pro, v7,
    if it can be done in what I already have and just haven't found how.

  3. For geometric distortions, including pincushion and/or barrel
    distortions, you could learn to use a utility also used for panoramic
    stitching purposes.

    Hugin is one of those, it's free, and it's getting better all the
    time:
    <http://hugin.sourceforge.net/>
    You'll only use a small subset of it's capabilities for just
    keystoning correction, but it does work quite well for that too.

  8. It is alleged that Roy G claimed:
    Do that, and I need to use the flash. Use the flash, and all I see is
    reflected flash flare. I know, I've tried. In order to not get flash
    flare and/or use ambient light, I +need+ to take the pictures at an
    angle.

    My choice of locations to take the pictures are extremely limited.

    Thanks for the suggestion, though.

    Guidelines for Legion of Doom Troops: 10. Test your armor's ability to
    stop a minimum of one sword thrust or laser blast, and if it does not
    give at least this much protection, respectfully inquire after
    something better.

    Photoshop Elements 4.0 has that feature, much cheaper.

    Can you fire the flash through a diffuser or bounce off a white card? I
    use a large (A3) sheet of white cartridge paper with the flash pointing
    into it.

  11. It is alleged that Prometheus claimed:
    Nope. I have three digicams of various vintages. None of them have
    positional flashes. I have two Sony Cybershots, an S-85
    (http://www.dpreview.com/reviews/specs/Sony/sony_dscs85.asp) and a U30
    (http://www.dpreview.com/reviews/specs/Sony/sony_dscu30.asp) and a
    Casio EX-Z500
    (http://www.dpreview.com/reviews/specs/Casio/casio_exz500.asp). The
    Casio's the one with the built-in Keystone correction ability.

    I will exchange the labels on my folder of top-secret plans and my
    folder of family recipes. Imagine the hero's surprise when he decodes
    the stolen plans and finds instructions for Grandma's Potato Salad.

    Perhaps a mirror to deflect the flash; I did that with the first flash I
    had for my SLR many, many years ago.
