Post by: julian kalmar on August 15, 2009, 04:03:05 am
-1200 raw pics Canon 5D MK II FL 100mm -> 310 for full sphere

-exposure between 15 sec. and 1/2 sec

-focus stacking and 3 wb settings (3000k, 5500k, 9000k)

-NN5

-PTGui

-3 days pc running to calc the sphere

-cube size 32768x32768 (5,3 Gigapixel)

-8 hours photoshooting

-2 month to combine the different focusing layers ,editing the WB and exposure layers

I was expecting some exceptionally boring technical excercise but this is wonderful - well done, both technically and a wonderful choice of subject

exceptional quality and detail,,

you can spend hours just slowly moving the lens around and enjoying all the small items you would never see in a normal photography,,

That is an amazing accomplishment!

Julian was too modest to include his URL in the post, so here it is.  Many other delights are there.

Wow! This is amazing. How does one publish cubic panos that are also GigaPixels?

Like Tim, I'm often disappointed with the artistic merit of panoramic stitches--they're usually more about being big than great.

You've done something special here--this is beautiful.

It would be nice to have a smoother browsing experience, but that doesn't take away from your accomplishment here--it's both cool and lovely.

Nice job!

Excellent shot and well worth the effort.  Thanks for sharing.

p.s. You're 3GP short of the world record though

I don´t think so
There are many larger zylidrical panos but this is the largest spherical pano

In two words: im-pressive.

I would be interested to know more about the WB edition, was it manual? what did it consist of?

Thanks for sharing this.  Your subject was well chosen for displaying detail as well as geometry.  While there is obvious spherical distortion that is inherent in the process, I see no stitching artifacts and the geometry, exposures and DOF work together to make for a seamless viewing experience.  I have no idea how you pulled this off, but stand in awe of it's technical accomplishment.  How many camera positions were required to not shoot yourself or support structure?

The problem with the WB: The ceiling is lighted with lamps that have 3000K, the daylight about 5500K and the small lamps you can see everywhere under the ceiling 9000K
I shoot everything in RAW, then I created the pano 3 times with different WB settings and mixed the three panos in PS.

The Dof problem I solved with focus blending. Some images do have up to 5 different focusing points.
The question about the nadir shooting will remain companies secret.... I worked really a long time to find a solution for this.
The nadir is not manipulated. I simply stitched the nadir images with the other images without any viewpointcorrection or stitching errors

Julian, I was expecting a brilliant piece of work - and I wasn't disappointed. All of your work that I've seen is superb. As someone who makes VR panos - modestly - I can easily appreciate the amount of work, skill and experience required to complete such a project. And patience of course.

I imagine that your nadir patching uses some type of viewpoint correction (can't see how else it could be done) but at this FL... blimey.

Thanks for showing us what can be done. I think VR panos are very much a poor relation to other forms of panography - probably because the web is the only display medium. Mind you the equirectangular projection of this pano would be stunning as a huge print!

I'd appreciate a couple of bits of info that won't impinge on your trade secrets!
Which head do you use? Which stitching application?

Nodalninja5 ( I modified it a little for my needs)
PTgui
..and no viewpointcorrection. With this resulution one would always see this.
