    Hello Kirk,

    15 meter, that's impressive !
    Except for the huge footprint of the panohead+remote control the results looks really fine.
    If there is an option to reduce the size of the footprint in such a way that it only covers the truck then that would be great.

    I can see that you rotated the mast by hand and shot 7 images round and because the yaw between the images is not equal I guess that for each image you had to lower the pressure and perhaps even have to collapse the mast to rotate it, am I right ?
    Can you tell something more about the workflow ?

    Best,

    Wim

    Wim,

    I didn't rotate by hand, I used a Bescor MP-360 motorized pan/tilt head with a wireless remote.

    The footprint is large because I put the receiver box on the side w/velcro. I didn't realize it would block that much of the shot, so I'll have to readjust where I put the box before I do my next tests.

    The images are not equal, because it's rotating remotely and there's no set rotation, so I just rotated until I felt it was far enough over with a bit of overlap.

    I used the WFT-E3A wireless grip attached to the Canon 40D to send the images down via 802.11g wifi. Since the 40D has a "live view" function, I could watch in almost realtime (3 frames per second or less usually) as the camera rotated, and then when I saw a good shot, I'd take one and then continue.

    It's also not equal on each shot because the wind was blowing, so the pole was moving a bit (I didn't have guy wires on it, which I really need to install)

    Hello Kirk,

    Thanks for sharing the details of your gear.

    I looked at the specs and the price of the Bescor MP-360 and it seems to me that the device is very usefull as soon as you find a solution to mount the remote controller behind/besides the camera.
    Perhaps you can place some kind of spacer device between camera and the drive, than the footprint of the bulky drive will be reduced a lot as well.
    And if you can make a visual aid, some small pointers ( 4 or 5) that are attached to the fixed and (1) to the rotating part of the base rotator than you can get a more precise position for each shot and than you also have to shot much less images.

    It seems to me that the WFT-E3A wireless data transfer device is pretty expensive but I guess that the live view support makes it worth.
    Personally I think of buying a EyeFi-Home wireless SD card + SD>CF card adapter + small pocket router to make a wireless connection to my MacBook Pro, the price of this combination will be under 200 euro.

    If you managed to get a smaller footprint I hope you can post the results and the info about the gear again.

    Best,
    Wim


    EDIT:
    This is totally off-topic. When I tried to order the Eye-Fi card @ Amazon.com I got a message that due to restrictions mandated by the manufacturer they could not delver the card outside the US.
    Customer service of Eye-Fi confirmed that this restriction is mandated to all US vendors :-(
    Despite the restriction I could order a Eye-Fi card @ Photojojo (no warranty/support outside the US).
    The setup wasn't easy but after I managed to get a reliable connection with the portable router it is working fine in a Canon 5D, 350D (both with a CF>SD card adapter) and a Panasonic FX30 compact camera.
    Negative issues: the wifi range is limited to approx. 8 meter outside in all camera's and the writing speed of the memory is terrible slow, compared to my Sandisk Extreme IV cards it is 7x slower !
    So the Eye-Fi wifi memory card is basicly a fun card (great fun :-) and not suited for Pro purposes.

    Great shots spyboy

    I have just started trying to use my fiberglass pole for panoramics. My original system was too complicated and I felt like my energy was sapped after trying to get an HDR still with my architectural mount and then shooting a spherical panorama. With the reduced complexity of my setup I can probably manage not to run out of energy The Bescor seems like a pretty good option to me for getting panoramas from a higher pole height. The cost is reasonable as well. Which model do you recommend? A real product opportunity exists for someone who develops a pole that is more rigid and can be extended in the vertical position as well. My pole easily fits inside of my car when I slide the passenger side seat back a bit and lower the seat a bit.

    Reduced complexity of setup
    I reduced the complexity of my pole setup and strapped the center pole from my manfrotto tripod with my NN5L attached and Canon 40D with quick ties. I use a wireless shutter release and try and set the ISO and fstop where I use a higher shutter speed to compensate for rotating the pole by hand. I do not extend my fiberglass pole the full 50 feet / 15 meters because it flexes / bends too much. I loosen the center knob on my NN5L so that it will not rotate.

    Don't see need to use wireless flash card
    I don't see any need to capture the images on the ground unless you want to see them real time. I already have USB cables with repeaters that I can daisy chain and connect to my laptop with timelapse software that will display the image from the camera (Canon distributes software that does the remote capture, but it does not work as well as my timelapse software that I can use to make adjustments to the camera such as ISO, fstop, shutterspeed, etc.

    Here is my attempt at a low tech pole panoramic. The light was changing and my photographs were shot at 1/100 to 1/80 of a second. I was planning 1/500 of a second. So my stitch in ptgui has problems. Autopano pro wouldn't stitch it well and It is much more trouble and time consuming to change control points in autopano pro.

    I did not expect this pole panorama to work because I started taking the photos at sunset and I could not realize fast enough shutter speeds. I used ISO 1600 @ f10 in aperture priority mode because the light conditions were changing so quickly.

    http://www.stoneyphoto.com/examples/...eld/index.html

    This panorama is a krpano multi-resolution panorama that will give a few errors about certian non existant tiles not loading.
    The largest resolution 1k tiles from an up sampled 24000x12000 image and does not contribute to increasing the quality as you zoom in.

    Hello Castillonis,

    Despite the difficult light situation the last pole isn't so bad at all.
    But shooting in automatic mode isn't the best solution to tackle the difficult dynamic range issue of the scene.
    If you can't get the results you want from a single exposure (please use RAW not JPEG) then you should consider shooting bracketed and fuse the results.
    Is it possible that the KRpano layer is set to fisheye mode ? I am sure it is a matter of taste but I don't think everybody will like it to see curved flagpoles that should/could be straight.
    The same for the corners of the building.

    Best,
    Wim

    Wim,

    Thank you for your constructive advice, I need it

    I always shoot in a mode that gives me both a RAW and jpeg image. The reason why I have been shooting the pole panoramas in aperture priority mode for sunsets is that I usually arrive with not much time to set up and I have not shot many of these. So, I feel like a dog chasing his tail in regards to the shutter speed when the sun is setting. Though, now that John Houghton pointed out that I need to take off the cylinder part on my fisheye lens, I might be able to get away with shooting one row, a nadir, and a sometimes optional zenith.

    In the few panoramas that I have shot, I took the pole down to change the pitch of the upper arm -30, +20, -90, 90 which takes some time to do safely. I stitched this together with the six -30 degree images and a nadir. I copied a section of sky to patch the zenith. So, I might be able to reduce the number of times that I need to raise and lower the pole.

    I now wish that I had purchased one of the manfrotto systems that you, the panoTwins, and Martin from czech360 use. I looked around at the time, but I was not able to find anything when I first put my system together. Now, I am aware of so many other options.

    As far as the fisheye parameter. I am not sure, I am using the default parameter settings. It may just be a wide FOV. I was working away at learning actionscript to make tours. I am a little overwhelmed by all of the stuff that you need to know. Currently I am trying to use the workflow that GURL (autopano forum) uses from a single series of RAW images.

    I wonder if Fanotec has contemplated a pole design? It would be more of a niche product with lower volumes. They would need to market it to landscape photographers as well as photographers that shoot panoramas.

    Boys will be boys. So when I came across a building site with a huge crane, I couldn't resist the temptation to make the highest pole panorama in history, using the 220ft crane as a tripod and vr-drive in one :-)

    http://www.duizelingen.nl/serendipit...es/At220ft.swf

    I did actually bring my Nodal Ninja up there, and used it to make some shots of the crane itself. For the panoramic view of Nijmegen (The Netherlands), the camera was locked into position however, and the crane driver agreed to rotate the entire crane 360 degrees. Unfortunately it's not possible to make a nadir image this way, so I inserted a nice mirror ball...

    For those who can read Dutch, there is an article on this panorama on my blog www.duizelingen.nl/serendipity

    this is not a 30m pole panorama. just a sidepole. but they are fun too.

    @pgiele

    Pierre despite some stitching errors (*) this pano is fabulous and it could be very well that this is the highest pole panorama ever made.
    I really love the view at Nijmegen, possible the number 1 of oldest Dutch cities with a history that goes back deep into the Roman time so I am sure that deep below you the archaeological department of Nijmegen spend a lot of time.......
    (*) On your blog you tell about the setup, I guess you used a Nikon 10.5 without a downtilt of the lens, that could explain the large footprint.

    BTW, I am not 100% sure but I think that the ViewPoint correction method of PTGuiPro could do a better stitching job for this particular pano with less errors on the horizon, not that is matters much because the pano is already very nice.


    @ ti360
    This sidepole pano is a real beauty and as far as I can see without errors.
    I know how hard it is to stitch such a side pole pano without getting errors so I take my hat off for this one.
    The scene is really great and it is obvious why this place is on the UNESCO list of monuments to preserve.

    All the best,
    Wim

    Yes I did. I can see two errors on the horizon. Possibly, I can edit them out in the cubefaces. I will try out the new PTGui version on this panorama, but in my experience, PTGui is not so forgiving with large parallax errors.

    i had newer heard of the "coast of ouddorp" on the isle of "goeree overflakkee" before. but i looked it up un on google earth. wery nice job with the beach pole pano. closer to the "vuurtoren ouddorp" would be fun.

    There will be no parallax as far as the distant horizon is concerned, and so that at least should stitch perfectly without any trouble. It will do so if you put control points only on features in the far distance and use a known good set of lens parameters (don't optimize a,b and c). That will also get your horizon flat and correctly placed in the equirectangular image (on or slightly below the centre line). As it is, the position of the curving horizon suggests the camera was some 37 miles above the earth's surface! Getting the distant landscape right does mean that you will get the expected misalignments on near features due to parallax. Dealing with those can be trcky and time consuming. In similar situations, I have used morphing and Photoshop's transform tools with layers, to coax the images into alignment. This one from the Monument in London was taken from camera positions around the top about 5m apart - giving huge parallax problems: http://www.johnhpanos.com/monument.htm. Note the flat horizon.

    Nice to see Nijmegen from so high up!
    I used to live in that city but I don't come there too often anymore, so this is a nice 'fresher-upper' for my memories : )

    Cheers!
