Way Useful Lens Database

Thanks to Nhat V Meyer of the San Jose Mercury News for posting (via the NewspaperVideo Yahoo group) a link to VRWave.com. It looks like the site is under construction, but it's already worthy due to its excellent list of lenses (Canon, Nikon, etc.) and their specifications for panoramic use.

Not only do we use fisheyes for panoramas, we can also use conventional lenses (both prime and zoom). And, we don't have to shoot full 360x180 panoramas - partial cylindrical panoramas can work quite well for story telling especially if you need a really wide view. If you remember the Widelux or Horizon panoramic film cameras, these panoramas will remind you of that"bananarama" effect. Here's an example I shot earlier this year where I needed to have both the building we were reporting on and the skyline. Another advantage of cylindrical panos is they're easier to publish in print - you don't have the extreme distortion at the top and bottom of the images as in equirectangular projections.

The database includes Field of View parameters for these lenses, and (this is the best part) it tells you how to set up a multi-row panorama. The key info is: pitch in degrees for each row, number of rows, and number of images per row. This is key information if you're going to stitch a multi-row, high-resolution panorama for posting to gigapan.org (see an earlier post for details). PTGui handles these multi-row panoramas quite nicely.

Where's Waldo?
Kudos to PghTrib.com for taking on the Gigapan camera and putting it to work for viewsers. This isn't exactly the photojournalistic use of panorama we've been concentrating on here on The Panoramist, but it has an incredible wow and cool factor.


GigaPan is a combination of hardware and software (Developed by Carnegie Mellon University in collaboration with NASA Ames Intelligent Robotics Group, with support from Google) that allows multiple images (often hundreds) to be shot precisely and stitched together into a large-scale multiple-row panorama. This allows for remarkable resolution in a single image, reminiscent of the photos taken by early photographers of American landscapes such as William Henry Jackson. Face to face with a contact print of one of Jackson's 18"x22" glass plates, one needs only a magnifying glass to go deep into the image. GigaPan gives us the ability to present this experience to our viewsers.

One could do the same thing with PTGui and a panoramic head, painstakingly shooting several rows of multiple images with a long lens and spending more than a few hours at the computer. GigaPan appears to streamline this process, making it accessible for us regular folks.

Do note, however, (quoting from the GigaPan FAQ): "Because a panorama is assembled from multiple pictures, sometimes you'll see strange things if something moved between the pictures." As photojournalists, we have to take this into consideration when shooting any panorama that requires multiple images.
