Use the High Distortion/Calibrate option in Stitcher... or upload some pictures, so we can take a look.
Why are you using F22 ?

It’s probably easier to put the camera on the pano head and take some test shots than using PTGui …
If you want 25% overlap for the middle row… you shoot 15 images, one every 24° (your pano head has this option).
… but, for the rows situated near the zenith and nadir you need less pictures.

You’re welcome
I’m not aware of any commercial full 360° Flash players, but Immervision has made one : immervision.com/immerv2/en/multimedia/multimedia_...
It’s possible to do a 360x180 panorama with a 28 mm lens, but this will probably require to shoot 4 or 5 rows x 15 pictures … are you sure you can process all those images ?
You need to defish only if you use Stitcher … PTGui, PTMac can stitch the images directly.

Hi,
The Nikon D200 is a very good camera, no problems there. It’s recommended that you shoot RAW (not jpeg), there’s more dynamic range to extract, it’s easier to correct the chromatic aberration and to make lots of adjustments… and a 16bit lossless workflow can really improve the overall quality.
You choose the lens according to the required output resolution : a Nikon 10.5mm fisheye lens on a D200 can create a spherical pano at about 11000x5500 pixels, with only 6+2 shots, for example.
I don’t think you’ll have much use for the macro lens … and that 28-xx lens (42mm focal length, if you take into account the 1.5x crop factor of the camera) will require at least 4 rows x 14 images, plus nadir and zenith … so, you need a wide angle lens.
An 18mm lens (27mm equivalent) : 3 rows x 10 pics +z/n.
The Sigma 12-24mm (recommended for Realviz Stitcher, as opposed to the Nikon 12-24mm) : 2 rows x 8 pics +z/n.
I have read on a few page that calibration of the lens is needed
If you’re referring to Realviz Stitcher, it has an option called High Distortion/Calibrate … but that's not the same thing as the nodal point.
You can find more info here : www.panoguide.com/howto/panoramas/setup_panohead....
www.edb.utexas.edu/teachnet/QTVR/NodalPoint.htm
services.manfrotto.com/303SPH/main.php?cnt=howto
If you don’t want to trouble yourself with nodal point adjustments there’s always the 360Precision panoramic head www.360precision.com .
Is it hard to stitch it together? What is the hardest part?
It’s not that difficult, especially if have a sturdy tripod, a good pano head, the correct nodal point and a bit of know-how.
What kind of panoramas were you asked to produce ? … full 360°, for web/print, inside/outside ?
It’s better to start making some panoramas now, before the actual project, in order to get some experience You can use the 28mm lens and Stitcher to do some partial panos (mosaics).
If you run into problems we’re here.

Hi,
You should start by choosing a camera and a lens …
One of the best solutions for panoramic photography is the Nikon 10.5mm fisheye lens + Nikon D200 (or the D70s, half the price of a D200) … 6+2 pictures are enough for a 360° pano.
You also need a panoramic head: Manfrotto/Bogen, Agnos, 360Precision etc. and a good tripod.
Software: PTGui works great with the 10.5mm lens – www.ptgui.com

I downloaded the pano so I can it in fullscreen  … doesn’t look all that great to me. The CA was probably corrected, but it still can be seen.
The source images were not sharp to begin with … so probably some sharpening was applied (notice how the leaves are not very well defined).
And there’s this ugly color noise all over the place … probably high ISO … or an older camera model ( I bet it isn’t a DSLR ).
I’ve spotted at least 4 stitching errors (near the left bench, between the benches …) … they could be indicating a 4-shot setup … with that HUGE fisheye adaptor, if you know what I mean.

Hi,
I’m glad you found my little tutorial useful.
Like I said, Realviz can stitch fisheye images, but it’s not the best solution for the Sigma 8mm … because of the extra work needed to defish the shots (+ some vertical FOV is lost in the process) and because it was not designed to work with fisheye lenses. Nevertheless, it is the easy way to stitch.
On the other hand, I hear that the new PTGui www.ptgui.com has improved significantly (fully automatic stitching, Photoshop Large Document .psb output etc.) … and all that for just EUR 70.21 (incl. 19% TAX/VAT).
I’m sure other users can post more info about PTGui, I’m not familiar with it … but you definitely must check it out if you plan to work with a fisheye lens (download the free 30-day trial version).
The latest Realviz Stitcher , version 5 is a step forward … but a small one (there’s an automatic stitching option, a rudimentary use of control points … and 5.0.4 can use Enblend ) … and, of course, it also came with a completely new set of bugs
About your problem: you close the pano after you stitch the last image on the horizontal row (no zenith/nadir images should be present).
Keep an eye on Autopano Pro too : www.autopano.net … fisheye support was promised.

Yes, it's possible ... The 10.5mm lens is a very good choice. You can go up to 7000x3500, or more, depending on the stitching software.
