My "Stepped-out" Panorama

Discussion in '35mm Cameras' started by Annika1980, Jul 14, 2008.

  1. I think something like that was done with cameras used in photo
    reconnaissance aircraft in World War II (and probably later). As I recall,
    the film was moved past a slit at a speed that was synchronized with the
    airplane's speed over the terrain being photographed, such that the result
    was a photograph in one long strip. Sort of a super panorama, only taken
    vertically -- and linear too, of course.

    Ain't it the truth. . . . I've learned a great deal in the newsgroups
    myself.

  3. PTGui pro supports it.

    Mainly for adding in the nadir image of a 360 VR, this lets you shoot
    without the tripod for the straight down shot. But it also works well
    for linear pans, in fact it works for any flat surface.
    <<<<<<<<<<<<<<<<<

    That's a flat surface. Even ^V + move tool in Photoshop handles that.

    Assume you do the usual 1/3 overlap. Consider a 90-meter building at a
    distance such that you get 30 meters in each shot, probably with a medium
    tele sort of lens. So you start at the left, move 20 meters to the right
    each time, and take 7 shots. (Are those numbers right/sensible? It's 4:00am
    due to terminal jet lag.)

    But there are a few randomly placed trees and street lamps 1/3 of the way
    from the camera to the buiding. Will PTGui Pro get those trees and lamp
    posts placed correctly obsucuring what they ought to be obscuring were the
    shot taken with a moving-slit camera?

    Panavue Image Assembler has a mode for flat field mosaics.

  5. As I've mentioned before, the ^V plus the move tool in Photoshop supports
    flat field mosaics. See my other note for the nasty case. (Truth in
    advertising: as usual, I didn't describe what I was asking carefully
    enough.)

    And it is _not_ completely impossible that some stitching program supports
    this.

    Nope, it does not handle forground objects when the camera moves
    between shots.

    What does help, at bit, is smart blend, which will try to get the
    whole of a tree or lamp in one frame, adjusting the seams to avoid the
    object in the foreground.

    But PTGui does is far more then PhotoShop, with PTGui the photos can
    be taken at any angle to the flat surface, it works out the relative
    viewpoints for the shots.

    Photos of a flat surface from a rectilinear lens straight-on shouldn't
    need any transformation, they should just line right up perfectly.

    Well, I'm none of those esteemed handles you quoted, but I do use DxO
    for developing my raw images. One of its attributes is precise
    correction of lens distortion, which seems to aid normal stitching by
    correcting the image beforehand.

    DxO IMHO is also excellent at automatically developing raw images. Just
    point it at the images you want to process, set the parameters you
    want, including highlight recovery. and let 'er go. About 40 seconds
    per image on a 3 GHz P4.

  9. Provided you can position the camera and preserve its orientation to
    within pixel accuracy. Can be done in an optical lab. A bit harder to
    do in a car park with a tripod :)

    And how many real world subjects that you might take from that car park
    will be truly flat? Bret's scene certainly isn't.

    That's why it's better to just silently K/F.

    Publically telling the plonkee is like announcing to a criminal you're
    about to call the cops on them before they flee away in the night.

    BTW, that RitaTard can stick that "D3" up its ahole. If there's any reason
    to NOT buy a brand, he/she/it has given it....AMPLY.

    Nikon may be far from perfect, but you can't blame them for Rita.

  14. I'm not sure I see the connection, unless you mean that informing the
    plonkee leads him to change his newsgroup ID. Indeed it may do that, but if
    so it shows that he hated to be plonked, and therefore the public plonking
    was at least somewhat effective as a punishment -- which was the reason for
    doing it, of course.

    Some users constantly change their IDs anyway, without being plonked. Maybe
    they *think* they're being killfiled. Who knows, it's strange behavior.

    I'd like to know how he aligned the lines when he did his stitching.
    I still can't figure out how to do one like I tried and get the
    shingles on the roof to look right.

    There are two things that will help with this kind of panorama, a
    whole lot of shot, to reduce the parallax from shot to shot and
    subjects that simply don't have much depth to them.

    In the ideal case you would only shoot one column of pixels between
    moving the camera, the image would still have odd distortions but at
    least you would not have miss matches at the seams between images.

    The only time this kind of shooting make sense is if you have a pretty
    near on flat surface that you are photographing, like the front of a
    building.

    Here is a tutorial on linear panoramas
    http://www.dojoe.net/tutorials/linear-pano/
    In his case the surface was very flat indeed.

    The trick is not to use Photoslop. It is probably the single worst
    program you could use to create a steppend out or liniar panorama.

    I did a quick and dirty example for the idiots over in Aus.photo who
    even today still try to badger me into posting a complete, highly
    profitable qand regularly selling picture of the hint I gave them.

    http://www.d-mac.info/examples/4theidiots.htm

    I used Corel Photo Paint X4 to blend the images and only used Photoshop
    for the "save to web" feature. No rocket science, just a bloody big
    monitor and visual alignment... Not a program in the world can do it.

    The real problem with creating a "stepped out" Panorama is not doing it
    but having the balls to experiment until you discover that only a small
    part of each image is ever used and you cannot use wide angle lenses -
    unless you shell out for a Leica F1.0 or similar. Even using an 80mm
    prime lens the images still need to be run through DxO Pro to "fix" the
    distortion in the images before you can expect really good results.

    Alan's latest "Rulz" alteration (#89 is it?) guarantee you can't make a
    liniar panorama that conforms to his idea of how they're made. Shit
    mate... 3 images = about 2x2 aspect ratio!

    Yes, Photoshop does have a steep learning curve.
    I can understand how you would have difficulties with it.

    But - persevere!

    Heck! One day you might even learn to spell.

    You are such a poor liar, Doug.
    That link, absurd and deficient as it is, has nothing to do with the
    "profitable qand regularly selling picture" (sic) you brag about.
    Remember this? http://www.mendosus.com/photography/doug.html
    Is that the "profitable qand regularly selling picture" to which you refer?

    Liar!

    You have never completed that panorama, let alone *sold* it to anyone.
    You haven't because you cannot.

    If you could, you would have displayed it here, if for no other reason than
    to shut us up.

    Not MS Paint?
    Nor can you, Doug.
    "Hey! Where'd my concrete path go? That grass wasn't there a minute ago!"

    Actually Doug, as a *ratio* that would be 1x1. Look it up. Along with
    "linear", "stepped", "and" and countless other simple terms. Not rocket
    science indeed.

    Doug, you're a fool, a blowhard and a liar.

    You probably can't help the first two, except by shutting up, but you can
    dismiss the last accusation by simply posting the fictitious Manly
    stepped-out panorama.

    Go on.

    Do the Manly thing.

    Post the pic.

    Idiot.
    Don't think for a single moment your bullshit and taunts are going to
    force me to post a photo I sell profitably just so piece of white trash
    like you can steal it.

    You are a copyright thief, a liar and fuckwit as well. Did I mention
    you're an idiot too? Get my property off your web site or suffer the
    consequences. Thief.
