Panorama Trouble

[Gabs]

I have some panoramaissues that isnt related to FPP, instead of getting the actual panoramaimage. I have a Nikon D90 with standard 18-55 lense and I would like to take a 360 panorama of a room.

If I take the 360 degree photosession at a vertical alignment parallell to the floor, im getting pretty good results. But in that case I end up with a panoramaimage that has a very low height and later in the flash panorama i wouldnt be able to look up or down as much as one would like.

To solve this i tried to take 3 photosessions around the room, one that has a vertical alignment parallell to the floor, one that is tilting upward and one that is slightly looking down at the floor. In this case I would end up with 3 times more images but they would cover most of the room both vertically and horizontally. Problem here is that the stitchingresult is quite horrible. I get ugly joints and edges and shit all over the place!

How do you guys take such panoramaimages that covers everything without ugly looking edges and stuff? :confused::confused:

Thanks in advance :)

Sounds to me that you
1. don't use a panoramic-tripodhead
2. the panoramic-tripodhead is not properly alligned for your lens.
Right?

You have to rotate your camera around the nodal-point of the lens. Check this website: http://www.panomundo.com/panos/howto/index.html

That might be a reason, Im using a tripod with rotateable head. But i havent configured it to rotate around the nodal-point. Ima check that out, how important is it to use a real panorama tripod like manfrotto rather then a regular rotateable tripod?

Thanks for your reply :)

Well, to make a proper 360 in your room, the camera has te rotate around the nodalpoint of the lens. Otherwise you'll get parallax (the name of the effect you see in our pano at the moment). Using a panoramic head really depends on what you want to do. If you want to make 360x180 VR-photo's, I would suggest to use a panoramic head, in every situation. If you want to make flat panoramics (something like this (www.patagonianpanoramas.com/peritomoreno/perito_moreno1.html)) You can do it by hand or by using a tripod.

Normally, parallax only occurs in the first 10-15 meters in front of your lens.

How important is it with a wideangle lense? Is it possible to do a 360x180 panorama using a 18-55 lense with a DX-camera?

If i had to buy a wideangle, would a Nikkor 10.5mm lense do the work?

cheers

[Cirrus]

Eeuh, the answer is 'Yes' and 'Yes'. I use a 10.5mm for all my panoramic photography. The wider the angle of the lens, the less images that you have to make. At 18mm for instance, you have to shoot 20 images in portrait-mode to make a 360 and have to tilt the camera +45 and -45 degrees and make another 20 images to get a full spherical panorama.
If you use a 10.5mm you'll need 6 images horizontally, 1 top- and 1 bottom-shot.
If you use a 4.5mm Sigma lens, you can do it with 3. The quality of this will be much lower though.

And, for a spherical you'll need a panoramichead anyways

[Gabs]

Okey sweet! The 10.5mm sounds great! Which panohead would you recommend with a budget around 400-800 $ for a Nikon D90+10.5mm

Take a look at the Atome if you are on a budget.
I use the 360 Absolute with a Nikon D200 & the 10.5

Here are the latest ones I just finished.

Looks good!

And atom with preconfigured for nikkor 10.5 was cheap aswell! And i suppose it works with D90? When i looked in the list for absolute no D90 cameras was listed!

Another question, when you use the 10.5 nikkor fisheye lense all the straight lines get VERY curved how do you straigten it out? :confused:

Thanks!

You can check with the folks here and see if a D90 will work.

Scroll down further on this page.
There are some samples - you need a stitching software like

[Gabs]

I actually have ptgui!

Will look into the samples

Note that the Atome is not supposed to be used with a small sensor and a lens like 10.5mm. You can only take the 6 around, You have to take the zenith by removing the Camera and do it handheld which is not a good idea as the zenith shot has to be perfectly in the right point also.

You need ether Adjuste or a panohead like the NodalNinja 3 or 5.
There are also other heads,
See my list here. http://www.panoramas.dk/panorama/panoramic-head.html

How about this one:
http://360tacticalvr.com/systems/rotators/nn3-mkii-complete.html
:eek:
Its even cheeper than Atome.. and it seems like its fully rotated supporting both the upper shot aswell as the bottomshot? Is NN3 good enough or should/must I go for the NN5?

Will the Nikon D90 work fine with this one? I couldnt fine D90 in their cameralist.. Will the Nikkor 10.5mm work aswell?

cheers!

My choice would be the nodal ninja too.
for it's price the gear is superb.
If I was you I would also buy the package that has the RD8 totator.
Exellent!
see this objectmovie I made..

klick and drag..

Wow! :eek: Very impressive objectmovie :D

What does the RD8 rotator do thats not included in the package i linked? Even with the RD8 rotator the price is splendid!

Nah... it's bad.... my camera was not stetup right.. moved the tripod a littlebit..
Need to redo it.....



the big difference is that you do not need to change the clickstop rings,
when you want to do a 4 -6 or even an 12 shot.

it is all in this rotator. it is also less wobbly (and the original was already pretty good)

it adds, 8 different degree stop increments (with equivalent number of stops around)
* 18 (20 stops)
* 20 (18 stops)
* 24 (15 stops)
* 30 (12 stops)
* 36 (10 stops)
* 45 (8 stops)
* 60 (6 stops)
* 90 (4 stops)


personally I did not try the Rotator R-D3L with built in new EZ-Leveler-II
http://store.nodalninja.com/v/vspfiles/photos/R-D3L-6-8-10-2.jpg

because I own the original leveler.

But think it will be top notch too..

The N5 is a good choice. It will last and last for you..
there are 2 versions. the NN5 L and the nn5 W
the W has 15 degree klickstops in it's upper arm.

Another question. When i looked at the panovideo over at 360precison the guy took his photos with nikon 10.5 mm and he didnt have to straighten them out before stitching them. He only had to do it with the nadir shot (the bottom shot right?) and did that with nikon software. My question is, can you do that automatically in ptgui aswell?

Yes that is no problem. Check my 2 posts here for ready made templates.

With PTGuiPro you can also use the Viewpoint action to stitch the Nadir directly with the other images even if they are taken from another point.

While using your template Hans i got the sideimages of the cube good but the top and bottom were really weird. Take a look at this image which is supposed to be the bottom one. What has happened?

I think you are using a panorama which is cropped.
Your spherical image should have the proportions 1/2.
Do not crop any empty black areas you may have from PTGu.

Also make sure that your output from PTGUI is not cropped.
PTGui may do that as default if your images do not cover the full vertical view.
After you have changed it to full 180x360 degrees in the Panorama Settings tab you may need to save it in the File menu as "Make Default"
