    Overall, the image has a slight lean to the left. In other words, the
    left side of the street is a tiny bit lower than the right. For an
    unsighted alignment, you did well in that regard.

    There is a slight bend upwards in the middle, because your camera was
    pointing down too much as you noted earlier.. It's pretty important to
    keep the camera level (in all directions) for this type of shot, unless
    you want those bends..

    Unfortunately, every stitch is obvious because of the lousy way Canon's
    software blends the images. The problems with this program are many -
    it doesn't seem to adjust exposure/vignetting issues, nor does it
    (un)distort the images in order to ensure all features match. Decent
    panorama software does both of those.

    I strongly suggest you download Autostitch:
    (download link near top) and give it a shot. The only problems I had
    with Autostitch were:

    - it would sometimes misalign features
    - you cannot intervene/control the program (probably a good feature in
    some ways!)
    - it choked on large panoramas on my system

    Hope that helps..

    That helps a lot, Mark, especially the info regarding the lens being down
    too far. I thought I had it fairly straight...

    I'll have to think about this and try to come up with some way to level the
    cam. A weighted string might work when I'm on level ground...

    I've done worse.... :)

    A couple of hints.

    1) Keeping the camera perfectly horizontal helps (in this case a wider
    lens and not tilting the camera slightly down could have made a difference).

    2) I don't know what stitching program you used, but most allow you to
    set various joining points manually (to sort out bad overlaps) and also
    have different levels of blending & color/density functions which can
    be activated or set (would avoid the banding caused by lighter & darker

    3) Manual exposure, to keep all frames exposed constantly (not true in
    *all* cases, but often is).

    Good luck & keep it up!

    Just a quick aside - Given we are probably only talking a couple of
    degrees, getting it level will be a bit of a challenge so perhaps it
    might be better to shoot in portrait mode? You'll end up with a few
    more images to stitch, but it will give you a bit of leeway in regard to
    getting everything in and not having to crop useful stuff off.

    Note that won't help with the 'bending' you get if the camera is
    pointing up or down. However, distortion in panoramas is sort of
    'expected', so it can be quite effective. Tell 'em it's the curvature
    of the earth...

    One last important tip. When shooting these wide panoramas, as with
    shooting with fish-eye lenses - make sure you keep your ears out of the
    Sorry. (O:

    Hope the training goes well,

    cheers, mt.

    Earlier (different thread) he said he used manual exposure for this
    image, so one would presume he left it the same for all shots. I think
    the effect is just mild vignetting from his kit lens - Canon's software
    doesn't even bother trying to correct this, hence my suggestion he move
    to something (anything!) else..

    Yep, the exposures were all the same. Since my daughter stitched them
    together using Canon's Photo Stitch (it was her first time using the
    program), no attempt was made to correct deficiencies. I just wanted to see
    how it looked "out of the [software] box.

    I'll have to sit down with my browser and see what I can find for tutorials
    on Canon's software, as well as the progs recommended by Mark, Jeff, and

    The next one will look better... How much? That remains to be seen... :)

    Good first go, Dudley.

    Now you're hooked.

    Since you've been good enough to share, I will take the opportunity to bore
    everyone rigid with some of my holiday snaps:

    These panos are all hand-held, and assembled in PS, manually.
    I do not suggest for a second that they are *perfect* (even "very good").
    Most have joins that can be spotted - some quite disgracefully so.

    They are all composed of about 5-7 images, usually taken at about "normal"
    (50mm/35 equiv) f.l.

    Exposure was auto - not manual (he shamefully admits) with adjustments done

    Every effort has been made to render the scenes faithfully - i.e. as an
    accurate rendition of the actual scene as viewed. No made-up bits and no
    cloned or copied bits.

    Yes - I know they are over-sharpened and show blown highlights - so sue me.
    I like 'em.

    Some file sizes are pretty big.
    I've included smaller versions, all with file size and pixel size indicated.

    Feel free to comment, but remember that these are holiday snaps, not
    competition entries. :)

    I felt I was driving into a textbook illustration of single vanishing point

    Do ya think? (O:
    I also noticed some of them are a bit foggy - did you clean your lens
    lately? (Sorry, I'm having a 'flippant' day..)

    Thanks for posting these, they are very good, and do a fine job of
    capturing the 'look' of the real Oz.

    I really like the first and last, and your perspective shot reminds me
    of an old SI submission of mine, (like you, any lame excuse to post

    I'd post more except for extreme laziness - plus I'm re-organising and
    moving my site to a new (cheaper!) provider so it's offline briefly.

    I'll second the AutoStitch recommendation. Just select the photos & push
    a button. Amazing.

    At that time of the day, I'm usually well in the land of nod, so the
    appearance of early morning fog was really something to me. Some of those
    valleys around Armidale are *really* pretty when filled with wet cotton
    Thx - although only one aspect, to be sure.
    You cheated!
    I took mine from eye height - no squatting!

    Its a difficult-to-resist tableau, yes?

    Well, I may have to move mine when the inventor of the internet shuts it
    down, but we'll see I guess.

    Sure thing, Alan.

    And, if anyone is interested in seeing how Adobe Elements and Canon Photo
    Stitch stack up against each other (no attempt to fix defects in either
    pic), here's a couple of links:

    That clinches it! AutoStitch it is for my next pano.

    Thanks, Paul, I need all the automation I can get...

    Has anyone else had a go at downloading these? I'm not getting the
    pano1-adobe.jpg example, but more importantly I'm getting corrupted
    areas in pano1-3 and pano1-6. Just wondering if it is me or my
    connection..? The rest seem fine. Reloading the bad images just gives
    me the same problems - the lower parts of the images seem to be tangled
    with others..

    I was going to run them through Autostitch, Hugin and PTGUI, all set to
    defaults, for some comparisons.

    Hmmm, not sure what happened there.

    I've re-uploaded panos 3 and 6, and I've reconverted the Adobe version /
    re-uploaded it.

    Let me know if that makes a difference.

    Sorry for the inconvenience...

    Me either, but I'm still only getting 1 of them - the adobe one seems to
    have worked, but these: give me a '404' (file not found). All the others are still there.

    Yes, but only a 33% difference... :O)
    No problemo. I enjoy challenges!
