Image enclosing could be part of your issue. You should set the circle to the "exact" dimension of the fisheye not under or over. This is the suggested method recommended by Easypano and how it is meant to work correctly.

Lens = Level

Panohead = Level

Enclosing Circle = Exact Size (apply to all images)

Update.

Here are some updates on my progress. All full Spherical Images can be accessed here:

http://www.uvm.edu/~khytten/nodal_pt/update_7.7.06/


Below are the images of nadir as I got closer to nodal. Ithought it might help new folks as they experiment. You can really see how tiny movements affect the image. I think I found it at settings 101 and 77. However, there are still some stitching errors at the zenith on that setting. Check out:

and
http://www.uvm.edu/~khytten/nodal_pt/update_7.7.06/Testing_101-77_final.jpg


I will also note that ALL pairs stitched with no mismatched points, Panoweaver is very forgiving.








The image below I think is very close to nodal. Notice the tripod leg in this image when compared to 78 and 76.





Don't worry, I still have the fun of finding it again when I get my quick release plate. And for a third time when I set up my personal setup with a Nodal Ninja. But at least I now know more about what I'm looking for.

Kevin,

To me (based on the Nadir shots) I would say the 101-77 is the correct setting.

Looking at your http://www.uvm.edu/~khytten/nodal_pt/update_7.7.06/Testing_101-77_ap9_infin.jpg panorama image in a viewer I still have concerns about the rather large "square" holes both nadir and zenith. This perhaps points to something in your software settings (most likely the fisheye enclosing). Try chopping some of the vignetting circle off (not all but some) and remember or mark your settings and keep trying.

I would have a go at stitching a set of your 101-77 images if you upload them.

Regards, Smooth

I also agree with the 101 and 77 version if for no other reason that I can see 3 panorama legs (not doubling of 1).  However, it also seems that the ceiling zenith is out of whack !  Odd.

Yes, when you have a moment post links to the 4 images and I'll have a go at it too please.  Sometimes letting others have a go at stitching.. might produce different results... hopefully better.  Of course we will provide the feed back here in the forum.

I don't have access to the above image sets this weekend, I'm visiting my parents. However, I took a number of shots today with as close to the 101-77 point that I could. I only have a trial version of Panoweaver on this laptop - but I see from some of them I am a little off the mark since one tripod leg sometimes doubles. Here is the link to the images I took today - they are in sets of 5. With the up shot the stitch ends up good enought if I wish to use them for my dads business web site - he owns a small motel.

http://www.uvm.edu/~khytten/nodal_pt/update_7.8.06/

The settings I used a minute ago for the circle were auto calculated at:

1164
1728
1734

It seems the disk look of the tripod is ok at 77. You guys seem concered about the amount of black showing, should I not see that much? And I did notice on these new shots something is funny with the zeinth stitching. It is still not coming together very nice. I think it could be leveling issues with the pano head I am using. The hot flash level will arrive on Monday with my quick release plate.

Kevin,

Mate, I'm too buggered to do it now 4.30am but I did just take a look at your Dads Office photo in Panoweaver and I now see why you are getting the "Black Square" your circle exceeds the photograph. Meaning it goes outside the photo at both the nadir and zenith points.

What camera are you using I.E: exact model and what size megapixel is it and also what model Sigma 8mm lens are you using?

Is the panohead and tripod the same as the one in the work office?

Will look more tomorrow sometime.

Regards, Smooth

Smooth,

Thanks for working so hard to help me out, here is the infomation you requested.

Camera - Canon Rebel XT (350D) 8 megapixel.

Lens - Sigma 8 mm EX for Canon mount (NOT the DG).

Yes, I'm using the same pano head as the work images. I have not done anything with my Nodal Ninja 3 yet. It is the Kaidan Quickpan with the Spherical Bracket. Here are some images:

Lens


Pano Head Images








The yellow tape on the sphereical arm is how I try to replicate the 77 forward and back mark for nodal. Right now I need to remove the bracket each time to mount the camera and then slide it back on to those marks. Once I get the quick release I will mount that to the bracket and lock down the bracket at the nodal point and leave it.

Thanks!

OK.. I think I got it.  Using Room 2 set of files [4 +1].  When PW4 asked me to put in more control points for the zenith +1 I said no.. to continue.  It generated a really GREAT final image set using the settings below. 

PW4 settings

X = 1164
Y = 1742
R = 1720

It does generate a double tripod leg.. but no matter.  You will probably put a tripod cap over the top anyway.  All the seams seem to come together.  You will note there is NO black square box at the zenith top.  The red line across the bottom is where the tripod cap goes into place.

For your lens.. not sure if the Quantray 72mm is the one you were thinking of for the fisheye.

Dave,

I got the Quantary 72 mm UV filter just to protect the Sigma lens. That was before I realized I must always remove the lens hood (which the filter is connected to) to shoot panos. I almost never shot will the hood on because I only do panos with this lens.

I also did room two earlier and thought it looked pretty good. I added another match point, I never thought of just saying no. I will be interested to here from smooth about the observations he has about the excess black area. I did see what he meant about the top and bottom edge of the circle not being present. My guess is it is just my lens and camera. It will be interesting to see how things come together on my personal setup - Canon 350D (Rebel XT) and a NEW Sigma 8mm 3.5 (I have one preorder). When I get the new Sigma 8 mm in I'll be sure to post some panos. It will be interesting to see if this new lens differs much. I might not notice but you and Smooth might be able to see some differences.

Since I do have a pano head that can shoot up (both for work and personal use) it seems I might be in good shape. The small part of the nadir will either be cloned out or capped.

Looks like I am as close to the nodal point that I am going to get right now, I think the double tripod leg is not much of a deal as long as the images come together nicely and I keep a nice round disk for a tripod head.   Thanks!
