Pano2qtvr streches zenith and nadir together.


Not 100% certain what you mean here as when Pano2QTVR converts from "equirectangular" you get 6 separate "cubic" shots generated, numbered from 0 - 5.

Shot number 5 will have the nadir in it's centre and shot number 4 will have the zenith in it's centre.

These shots can be edited individually in PhotoShop (or whatever you use) to either repair any unwanted image or add a nadir or zenith "cap".

With the Immervision player it all depends on your original filesize and image size/quality settings.

Once you go below 3000px x 1500px with Immervision you will noticeably lose quality, especially when you go full-screen.

QuickTime is certainly the best format for quality and everything else is always a compromise between quality and filesize.

I have just moved away from QuickTime and have gone over to the Immervision player but this is purely because I can use smaller filesizes on my server while maintaining reasonable quality.

Hi Olivare

The D80's sensor is too small to capture the complete circular image from the Sigma 8mm. i.e. The image will be cut off on two sides.

You are better to use the camera in a vertical format, which will give you almost the full 180 from ground to sky (or nadir to zenith) and then take at least 5 shots around the 360 degrees. This will give you more overlap and aid the stitching process.

You can get away with 4 shots with the Sigma/Nikon combination, but only just! You'd be better to play safe and take 5, 6 or 8 shots.

PTGui is certainly the best bet for stitching although you will still need additional software to patch the nadir and zenith.

Once I have stitched in PTGui, I import the PTGui stitched shot into Pano2VTR (Free) and then convert to cubic format. When this is done your nadir (the ground) will be in cube face 5 and your zenith (the sky) will be in cube face 4. These two cube faces can then be edited individually in PhotoShop (or similar) to patch the nadir and zenith, then the cube faces are converted back to equirectangular in Pano2VTR and your 360 x 180 shot will be complete!

Pano2VTR will also output your panorama in QuickTime format in the free version!

Like all photography there are many ways of doing things and this is just the way I do it. Others will have different workflows and different preffered software.
