“Virtual” Learning Curve – Figuring out QTVR Panoramas

Friday, February 22nd, 2008

The past few days I have been stitching and re-stitching a 360 by 180 degree panorama I shot in my living room. I have not had the opportunity to take any in other people’s houses, so I have to practice with my own. The learning curve of Hugin (the open source panorama creator I use) is pretty steep, but I am figuring out the nuances of the program and what I have to do to make it stitch efficiently. Hopefully in a few weeks I will have the whole process down well enough to write an article on it. If that happens, you will be the first to know! Check back in the near future for new photos and panoramas.

Virtual Reality Panoramas (QTVR)

Tuesday, February 19th, 2008

As I mentioned in my last entry, I bought a Sigma 8mm f/3.5 circular fisheye lens. A couple days before that, I received my Nodal Ninja 5 Lite in the mail. The Nodal Ninja is a panoramic tripod head that allows you to pan horizontally and vertically around the entrance pupil (sometimes called ‘nodal point’) of the lens. This ability prevents parallax between photos when taking single or multiple row panoramas. This past weekend, I used my two newest additions to my photographic collection to create a QTVR, or Quick Time Virtual Reality panorama. By taking 6 photos, one every sixty degrees, one photo straight up, one photo straight down, I captured the image data needed for a panorama 360 degrees around and 180 degrees up and down. I used Hugin, an open source, free-ware software, to stitch the photos together, and Pano2QTVR to convert to a quicktime movie file to view online. The photo below is a link to the final movie. When/if I master this process, I will write an article about it.

New Lens: Sigma 8mm f/3.5 Fisheye

Friday, February 15th, 2008

Woohoo! I just received the newest addition to my photographic arsenal in the mail today. I ran out of sunlight pretty soon after I got home from work, so I was not able to take many shots. I ran outside right after opening it to take the obligatory “straight up” shot in my backyard, shown below cropped to a rectangle.

I am going to Pennsylvania tomorrow and I plan on taking some photos up there. I will be back Saturday afternoon, hopefully with some photos to show. Have a good weekend!
