Creek Panorama

Cedar Creek,

Queensland,

Australia.

This is the fourth bridge over the creek and the spot the kidlets swim in when it's hot. Five 10mm shots stitched together using Hugin for a roughly 180 degree panorama.

    ooohhh nice.
    It's a shame about the car and the drain but a nice photo nonetheless.
  • David de Groot said:
    Well the drain is the bridge, as such, but yes, it's not very exciting. As for the car, that's my truck. I don't usually park there for these shots but didn't expect to get anything worthwhile anyway.

    Nice one Dave, I think the panorama has worked well in this shot.

    I need to get some panorama practice myself seeing as I screwed up pretty much every one I tried when I was on holiday :(
  • David de Groot said:
    Thanks Kenny. I'd suggest a tripod for starters, but it's not entirely necessary if you have a steady pan motion. Aim for at least 30% overlap between shots (sometimes more for wide angle lenses), and then spend some time with software like Hugin + Autopano + Enblend, or AutoStitch or AutoPano Pro. Such software works far better than photoshop or the Canon PhotoStitch software when it comes to putting these things together seamlessly.

    Nice job! And I've also read your pano advice with interest - ta!

    Seen on your photo stream. (?)

    nice one dave... The para really suits this shot. Pity about the truck! however, and thanks for the info re: pano software, might have to give this is a go! :-)
  • David de Groot said:
    Thanks :) Stitching with the 10mm is always interesting as although I could get the same perspective with just two shots, the distortion is usually too much for the stitching program to handle, thus the need for five shots to get this (four might have done it really).

    Oh I dunno, the truck adds context, shows it's a country bridge.

    Thanks for the tips Dave, I did use a tripod with levellers in both the legs and head. However for quite awhile I wasn't levelling the legs just the head or sometimes just going off sight and that seems to have screwed around with the perspective of the shots. Then even the ones I did with the legs levelled are still kinda screwed up so I am not sure what I have done wrong. When I say screwed up I mean that in one photo the distance between 2 objects will be greater than in another photo so they don't match when put together. But perhaps if I try the software you have said I will get better results, as I was just using photoshop. You'll know if I am successful :P

    I don't mind the truck being in the picture either, although it is hard to say if I would prefer it without the truck, without seeing a picture without the truck :)
  • David de Groot said:
    Ah yes, the joys of perspective and a rotated viewpoint. The stitching software handles that by distorting the images such that they all match up nicely. You usually don't end up with a nice rectangle image, it's more bulbous in places but then you just crop accordingly.

    Groovy shot David.

    KennyWP, what you're experiencing is parallax, and it is due to your lens not being perfectly centred at its entrance pupil. Achieving perfect alignment is pretty much impossible to do without a slide mount or a panoramic head, and even then you will need to perform an alignment process based on trial and error.



    Check out the comments on this photo for a bit more information about achieving a true parallax free panorama.
  • Shaun Johnston said:
    David is right - Hugin uses an external piece of software called SmartBlend that basically 'averages' the difference between the edges of two images and tries to make the blend as smooth as possible. Sometimes it will mask Parallax problems nicely (normally if they are insignificant), but other times it may even exacerbate them.

    A nice piece of work David. Like the truck. It adds realism.

    Thanks Keith :)

    lovely work. good to finally see some pics taken with the 10-20. Gives me a better idea of what to expect.

    Have yourself a very merry! Enjoy the studio lights. I'm lovin' mine.
  • David de Groot said:
    Lots of 10-20 pics on here (pretty much a mix of Sigma 10-20 and Canon 50mm f/1.8, with forays into other borrowed lenses when Johnno is in town). :)
