It is but the overlaps are small.

It might be possible but you certainly need a nadir and a zenith shot. I processed your handheld panorama with cubic converter to show you the "black holes" that need to be filled.

Well, I don't know, if you have noticed, but the second house with columns is across the street and not a part of the first house with columns.
Where can I get "cubic converter"?
Thank you!

Hi,
I was thinking to get digital level to help me to level my pano setups. However, it is magnetic and I am afraid of magnets effect on my camera. Can it spoil something in the camera, if it is placed very close to it?

Thanks!

Thank you Paul, but I want actual degrees readout. Otherwise, I can use bubble level.
I guess I will call manufacturer and ask, if magnets can be detached.

Yes, you will need a zenith shot (say at +60-65 degrees pitch), in addition to 4-around, for close to 360x180 coverage.

Screenshot below is of the nadir when shooting 4-around at -10 degrees pitch on a Canon cropped sensor body, usinha  Noidal Ninja R-D3L rotator. You can see that the 'hole' at the nadir is quite small.

How did you shoot that Nadir?
I shot mine at -60-65 on NN5 in opposite direction and it is bigger than yours. Also, the view of a tripod similar to yours is visible only in SWF when played.
Can I upload it here?

I didn't shoot that pano, I don't have a Samyang FE lens myself, it was shot by 'Smooth' from panoguide.com.

I just wanted to show you that it is indeed possible to get 360x180 coverage shooting 4-around+Z+N with the Samyang FE on a Canon cropped sensor body, and I'm told the overlaps will be a little bigger with a Nikon DX cropped sensor body.

The image I posted was a screenshot when displaying the Flash VR of the pano.

The Canon APS-C cropped sensor is a different size from the Nikon DX cropped sensor. And the R-D3L rotator (excluding the leveller element) has a larger diameter footprint than the rest of the R-Dx range of rotators - 73mm for the R-D3L vs. 62mm for the R-D16/R-D8 vs. 54mm for the R-D4.

If you want a smaller nadir 'hole' just try pitching your camera/lens down a bit more for the main row. I don't know how far you can go before you find the 4-around no longer overlap with a 'zenith' shot and each other; or maybe that doesn't happen..

Errr... what do you want to do with it?

Adam wrote:

I want get rid of tripod.
How?

Several options:
1. Leave it as it is but restrict the FOV in the Flash VR player so people viewing the pano cannot see the part of the pano with the tripod. This is simple with Pano2VR, and can be done with krpano but APT doesn't seem to offer a simple means of setting the viewing limits (yet?).

2. Cover the area of the tripod with another image - a so called nadir 'cap'; this could be a branding logo, or a mirror ball and so on. Pano2VR's patch tool offers a very simple way of adding a mirror ball. APT allows you to set a nadir 'cap' image.

3. Patch the tripod area at the nadir with another nadir shot taken without the tripod in view. This involves using an image editor that supports layers such as Photoshop. The patch tool in Pano2VR makes it much easier. This is a bit of a 'black art'; there are probably just about as many methods/techniques of doing this as there are people doing it.

Here's some more info about Pano2VR's patch tool:

Does this help?

Wow, how did you do that? Step by step please.

Adam,

that one was easy. I just copied the left side of this wonderful carpet. This gave me a new layer after insertion of the copied piece. I mirrored it ant placed it over the tripod on the left side. I reduced the opacity of the layer, containing the copy of the carpet to 70% to place it correctly over the pattern of the background layer. I flattened the image and got only one layer. With the dodging and burning tools and the cloning brush I did final adjustments. That's all. It took less than 5 minutes to finish. I wish I always had jobs like that. Nice and easy going. But most of the time they aren't.

For the mirrorball you can find ready made actions to install in Photoshop. Example: http://wiki.panotools.org/Adding_a_nadir_cap_(mirror_ball) . Here is a tutorial how to create the mirror-ball http://www.nyfeler-mueller.ch/TripodCap … apText.htm

Hope this helps Adam

Thank you for your help.
The second example doesn't work, because I get this error (see attached). Where can I download latest pano tools from? Maybe that's my problem. My pano12.dll mybe bad.

The first one is pretty easy to do, but cannot figure out (yet) how to put text into nadir cap

on full frame you can take 3 around to get a full 360, on crop, you most likely will need 4 images.
