360° - Szabadság szobor

A kép eredetijén nem érvényesült igazán a látószög, ezért kicsit megkavartam a vonalakat. Érdmes megfigyelni, hogy a jobb oldali zászlórúdnak a kép közepétől balra húzódik az árnyéka, nem messze a másik zászlórúdétól. A meridiánban hossztartó hengervetület már csak ilyen :)

Gratulálok, hatásos kép. Megkérdezhetem, hogy mivel készítetted a torzítást?

Ez egy Gömbpanoráma , 360°*180°látómezővel. Technikailag 5 kép halszemobjektívvel, de bármilyen objektív jó hozzá (csak sokkal több képet kell csinálni). Azért lett ilyen, mert a horizontot a szoborra állítottam a feldolgozás közben.

Hello, I feel dizzy. :)

I'd like to make this projection pano in some day. Could you answer to my few questions?

*What is this projection method?

*What software do you use to stitch this projection?

*What pan head, camera and lens do you use?

I know I have to learn treating nadir correctly to do that, a challenging part...

Hello SOG!

This is the standard equirectangular projection used with spherical panos. During the alignment in the stitching software I placed the horizon above the "real" horizon. That's the cause of the extra distrotion.

My processing method is a bit complicated, but it's proven.

1. I shoot in RAW.
2. RAW processing & WB with PS.
3. Aligning, stitching with PTGui. For stitching I use plug-ins: Smartblend for the spherical panos, and Enblend for "normal" panos.
4. After I stitched the pano, I convert it to "cubic" wit Pano2QTVR. This makes 6 cube faces from the equirectangular source image: 4 sides, Zenit, Nadir.
5. PS again: I fix some stitching errors on these images if it's required. And here comes the big magic, I retouch the nadir. The "patch" tool is perfect for this.
6. After finished I go to Pano2QTVR again. I reassemble the equirectangular image from the cube faces.
7. PS: color, tone adjustment, finishing touches.
8. "A" Save for web @ geotagging, upload to Panoramio "B" Pano2QTVR: generating the QTVR movie.

I use an EOS 350D, a Peleng 8mm F3.5 circular fish-eye lens, and a home-made wooden pano head designed for the 350D & Peleng system (but maybe I'll purchase a Nodal Ninja, or make a new metal Pano head). With this lens I have to take only 4 images plus a fifth Zenit shot if needed. Only a football sized space is left out under the tripod.

The free GNU stitcher, Hugin shows some promise, I think it will beat PTGui in the near future.

I appreciate your quick response. Now I know the secret of this skewed pano. I noticed you already explained the method above. I had to try on-line translator before asking. Sorry bothering you.

I knew the method to stitch nadir. Two reasons I always skip this part are... 1) difficulty to take nadir picture keeping camera level and still as possible. It is hardly possible especially in low light environment. I need Gitzo Explorer. 2) difficulty to retouch in post stitching process. I need more skill to do it.

DSLR + circular fisheye is the most powerful combo in the pano world. That's my dream. Less effort/pain of taking picture and stitching but more costs. I'm tired locating control points to stitch over 30 fragment pics. Unfortunately I cannot afford them at this time.

Nodal Ninja 5 is my second pan head. I upgraded from an old single row pan head from Kaidan. The Ninja works really fine with my rigs.

I used to use VR worx from VR toolbox and Stitcher from Realviz for years. Hugin is my friend these days. PTGui has good reputation around me. I will try it later.

Thank again for your reply.
