Thanks.
FYI I can view it completely with any browser on MacOS 10.5.5 (Intel), Windows XP and Vista but it always lacks the last tile when played on MacOS 10.4.11 (PPC G5).
All with QuickTime 7.5.5.
Another QT quirks?

Juan,
You may have changed something to make the QuickTime movie now available. The gray preview is now viewable but the final image stops loading before completion

Awesome VR!
I could not view it in QTVR format though: The movie seems to be missing as there is the dreaded question mark on the blue Q.

The reason I wanted to try your source pics was because most of the Coolpix camera with either the FC-E8 or E9 have a FOV of 183°, so I wondered if IIS could stitch your images with 182.6° FOV.
The only advantage the Coolpix 5400/FC-E9 has is a FOV of 190° which makes stitching really easy. It was the only Coolpix with this bigger FOV
Doug,
FYI: the FOV of the (CP P5100 +FC-E8) combo is much larger than 185° with the Nikon UE-R20 original adapter.
Anyhow, I have shortened the Agnos "clone adapter" and the resulting FOV is larger than 192°

Ken and Dorin,
Sorry to be slightly OT, but if I was expecting not being able to view Dorin's pano on my Mac as DevalVR is not yet available for this OS, I was really dismayed not to view any of Ken's three proposals either.
It's not a question of memory size there. A dreaded red cross is visible on the upper left corner and one can read: "Applet Stereotest notinitiated" (exact spelling) below a full white window".
It is probably the first time I get a problem for viewing a Java based VR on this configuration
Regards,
Michel

Hi Nick,
If I have ever mounted the Nikkor 10.5 mm on my EOS 5D since I shaved the rival Tokina 10-17 mm, it was each time for experimentation or test only.
Despite its slight edge in max. aperture, I do not plan to use it operationally any more.

Hi Bernd,
QTVR opened and runs fine on my Mac.
I am impressed by this close-up panorama. Stitching is very good and despite having sharp shadows elsewhere you've managed successfully to not show any apparent shadow from the camera.
Well done.

Hi Hans,
Hans Nyberg said: Thats because you are not able to control your FOV in Autopano as you easy can in PTGui.
Well perhaps it is somewhere but I have not found it even if I have looked a lot for it.
It is not directly obvious what you get of optimized FOV,
On the Panorama Editor of AutoPanoPRO (APP) tool bar, you may click on the Image deplacement mode button (blue crossed Icon with four arrows). Now in the info table below the image window, the "Fov" column has appeared. You can tweak the value of Fov of each image. But there is apparently a bug that keeps from putting more than 180 deg even if it was >180 deg before you attempted the change. Optimizing again restores the >180 deg value !
Optimized FOV is not always the right FOV.
Yes, I have observed the same. But the panorama may be seemingly good and complete even with a too small reported FOV for instance, and this puzzles me. There must be some image correction parameters that are activated but not reported.
...
In addition to that the autodetect cropcircle in Autopano is not very good.
You will sometimes get a too small crop but often you get one outside the the actual image.
True and ennoying, but with my fisheye lenses, the autodetect cropcircle is neither better nor less precise than PTGui's. They could both be improved to become useable!

Hans Nyberg said: Forget about Autopano. David is on Mac
It is extremely slow and not at all a good solution on Mac.
I have not tested the windows version.
Speed compared to PTGui is in the area of 7 minutes for PTGui and 25 minutes for Autopano.
This is for a small 8 bit 7000x3500 panorama from loading setting up without a template, running controlpoints/optimizing and warping/blending final panorama
Hans
Hi Hans,
I am currently running a comparative evaluation (4 different software) of automatic stitching and rendering of "2-shots" spherical panoramas .
(Mac OS 10.4.11 2x2 GHz PPC G5)
On a typical example:
Fine tweaking included, it took 3 mn 20 sec (50 CP requested + High quality CP detection level) or 2 mn 15 sec (50 CP requested + Medium quality CP detection level) to get the panorama ready for rendering on APP 1.4.
The same operation lasted 2 mn 55 sec on PTGui 7.8 (15 CP requested).
As the source images are unfortunately deprived of useful EXIF infos (because I've used a fisheye converter), it all depends on my personal skill especially for quick circle cropping
The time could be of course reduced by using a template for further projects with similar images.
Rendering the project output panorama (JPG; 5000x2500) on APP 1.4.2 with Smarblend took 1 mn 22 sec. Note: APP 1.4.2 is a beta version.
On PTGui Pro 7.8 it lasted respectively 55 sec with Enblend, 1mn 15sec with PTGui blending and 1 mn 42sec with Smartblend.
IMO it's hard to say which one of these two SW is the fastest for this specific 2-shots case even so speed is the main criteria.
Regards,
Michel

Hi Doug,
Doug Aurand said: Tom
I've read the comment that the E8 is sharper, but whn I used it on the Coolpix 800 and two 950s I have, it was very prove to lens flares.
Part of the technique of 2 fisheye shooting is to "split the light source." This balances the light in both hemispheres.
With a bright window or sliding glass door on the edge of the lens there was almost always a lens flare opposite it. I figured out a very effective way of "patching" the flare with part of a second shot that I blocked the light source.
With the trimmed adapter, the flare from the FC-E8 is rejected outside of the image circle, in most of the panoramas. This is another benefit of the adapter "shaving" operation.
However this is not always fully true and the glare and the veil of light that may come together with the flare as a side effect can sometimes be very visible.
This is an exemple where you may observe glare, flare and veil while the rest of the image is decently sharp:

I reckon it is 32.2mm.
That is from rearmost surface to top of the 'ridge' around the front thread.
Is that 'good' or 'bad'?
Andrew
Thank you Andrew for this information.
That's exactly the same length on the original and on the clone.
If I am right, all the Nikon UR-E20 or Agnos AFCE8NP5000 adapter users are deprived of the huge FOV of the FC-E8 + CP P5100 combo if they do not shave this accessory.
I know that Agnos is now probably aware of my findings...
BTW: with pairs of images shot with the above described combo and others, I am extensively testing the capability of several popular software for Auto-CP Detection and Auto-Stitch of 2-shots images.

There are setups for the P5000/P5100 using the FC-E9 and 360Precision maks a rotator for it. Its a good set up but understand that it was an accident that some one figured out Nikon made an adapter that would mount the FC-E8 on a camera that was never planned to use the FC-E8. In the samples and source images I've played the overlap looks like its just barely enough when do 2 fisheye captures. With three fisheyes its great.
/quote]
Hi Doug,
I have found exactly the opposite from my experiment and use of the CP P5100:
The useful angle of view of the FC-E8 mounted in front of this camera could be be as large as 192 degrees
The Agnos adapter (for CP P5000) was obviously designed with too big a margin in length for accommodation on this specific CP P5100 newer camera.
I have "shaved" this adapter to reduce its length in order to get the largest angle of view while optimizing the TCA and sharpness. The resulting angle of view is ~190 deg. and the adapter can still be used also in the "Tele" mode as well.
Details are here:
michel.thoby.free.fr/DuoPix/DuoPix_solution.html
Read "Getting the largest angle of view (shaving the adapter)"
BTW: Three months after order, I am still waiting for the delivery from Nikon of the UR-E20 adapter to perform the same experiment
Could somebody measure the length of this Nikon genuine accessory (with about +/-0.3 mm accuracy or better) and then report the result?
Regards,
Michel
