Hi I thought I would offer up some images for advice from the panoramic experts on the site. It is a brand new area for me as I tend to specialise in wildlife and nature photography. However seeing some of the panoramas being produced has given me a push to try my hand at them.

All of the images located here http://www.photosbykev.com/wordpress/index.php/photography/panoramic/ are taken with the NN3 MkII supporting a Canon Eos 40D and 17-40mm or 10-22mm lens fitted with grad ND filters and/or polarising filters to balance out the ground/sky exposure. I tend to shoot bracketed images to maximise the dynamic range of the images. Process them in Photomatrix and then stitch in Panorama Factory v5 and then upload to my site using the Zoomify export option in Photoshop CS3. This allows me to show the full resolution of the >1Gb images without significant risk of image theft.

Any thoughts would be more than welcomed as I have a lot to learn in this genre of photography.

ps After taking receipt of the NN3 MkII I was immediately impressed by the engineering design and mechanical build quality, it has been a real pleasure to use )

regards
Kev Lewis

Excellent shots. I am particularly impressed with the stitching of the sea in the first shot.
This often creates considerable problems of continuity.
Very well done.
I can see you getting deeper into this branch of photography.

Thank you Terry, I knew in advance that the breaking waves would be an issue so I tried to time each shot to keep the wave crests in a similar position and I took plenty of spare images :001_smile:

Kev,

Nice work. any way to open the panos in larger window or full screen?

only if I increase the size of the java/flash applet Nick. Currently it is set for 500 pixels x 500 pixels because that suits my site layout. I have tried other panoramic viewer applets but they load the full image at the start and the image needs to be relatively low resolution and heavily compressed to keep the download times short. The current applet is using over 1,500 tiled images of varying resolutions so as you zoom into the image the higher resolution tiles are loaded. Doing it this way reduces the download times significantly for the viewer and maximises the detail visible in the images. It does distract slightly not being able to see the full pano and it doesn't allow a continuous rotation of 360 degree panos.

Kev, To me, "panorama" and "zoomify" are a contradiction in terms. The essence of a panorama is the wide view, and I find the blinkered view from zoomify tedious to explore, though not without interest. It's ok if what you want to do is impress with technique; but like Nick, I wanted to see much more of the panoramas at a decent size. Panorama Factory is not the best of stitchers, and zooming in does tend to reveal some stitching errors. Once one has been noticed, it's hard to resist the temptation to hunt for more! As a beginner in this field, you've made an excellent start, but I suggest you try one of the popular Panorama Tools based stitchers (e.g. PTAssembler, PTGui or Hugin), and maybe reconsider how you display your images on the web.

I fully understand where you are coming from :001_smile: Can you recommend a suitable java? based applet for displaying panoramas that have differing FoVs rather than complete 360 ones?

I'm afraid I don't have any particular experience of java applets for panorama display. I know Ken Warner has been developing one at http://www.pancyl.com . How far that might go in meeting your needs I don't know, but you would find him very helpful if you had any special requirements.

Thank you for the response John :001_smile: I found one that works inside wordpress which I use for my website but I will check out Ken's site as it maybe better than the one I've chosen. Perhaps you could relook at the main link http://www.photosbykev.com/wordpress/index.php/photography/panoramic/ and check out the viewer option which I have added to each of the panorama images. Each of the viewer images are 3000 pixels wide and about 500kb, just click on the image once it is loaded and move the mouse left or right to scan through the image.

Kev, the alternative viewer is somewhat more convenient, but it's still a small square window on my widescreen monitor. It cannot convey an impression of a majestic panoramic view. I would far rather just have the whole image straghtforwardly displayed in the browser, and rely on window scrolling if and when necessary. But that's just me.

Sounds like I need to a add a straight popup window to display the full image in another window. Thanks for the input John :001_smile:

I've had a play with this applet and been in touch with Ken about it :001_smile: it works very nicely http://www.photosbykev.com/java/panotest2.html

Yes, I think that's a lot more acceptable than your previous versions.

Final version testing of the panorama applets out there at the moment, this one is flash based http://www.photosbykev.com/panoramas/churchbay/churchbay.html . I will settle on one applet for my website after I get any feedback. Is it worth going this large for instance??

The image file is 2Mb so it will take a while to load. Right click for Full screen viewing Esc key to return to normal window

That looks fine, though you need to manage the horizon better in order to get it level. I assume it was flat and level in the original panorama image.

Nah John it was naturally curved :wink: It is something I'm struggling to fix at the moment because the images are a single row panorama so rectilinear ? and I can't find the correct command to set the horizon point.

(edit) the horizon is much closer now I was over estimating the vertical field of view :sad:

If you use PTGui, there are several ways of levelling the panorama. One way is to do it visually in the Panorama Editor window. Make use of the fact that the line of the horizon should be flat and run straight across the centre of the output area. You can click on the "Edit entire panorama" icon and drag the panorama into the required position. Rotate by dragging with the right mouse button held down.

The fact that it is a single row stitch does not mean that the panorama will necessarily be rectilinear. For a wide angle view (>100 degrees, say) you would use cylindrical or equirectangular projection.

The horizon on the stitched image is dead straight in PTGui but is above the horizontal centreline of the photograph as the camera was tilted a few degrees downwards deliberately to take the horizon away from the centre as it improves the composition, imo shooting with the camera truly horizontal just cuts an image in half with the horizon and it doesn't look nice to me at all. I've adjusted the vertical FoV on the flash player to remove most of the curvature so it should look better.

I think I am inclined to stay with the FPP Flash player for my site as it does allow the full screen view and is relatively easy to program.

Kev, It doesn't matter whether you tilt the camera up or down when you take the photos. Either way, the horizon will be flat and level when it is half way down the output area. If you tilted the camera up, there will therefore be a blank area at the bottom of the output panorama that will need to be cropped away in Photoshop. V8 of PTGui (expected in the next few weeks) will have a new cropping feature on the Panorama Editor window so you can do the crop before stitching).

I will be interested in seeing what the v8 has to offer :001_smile: One of the nicer features of Panorama factory was the auto crop not that it takes any time in CS3 to crop the image manually lol. I will keep on learning.

Thank you for your input John it's appreciated
