EquipmentHand-held Canon GL-2 video camera, zoomed in somewhat. Superimposed images from Pentax Optio W30 video sequence. Edited with Final Cut Express, Photoshop CS, QuickTime VR Authoring Studio, and QuickTime Pro.
Behind the scene : how this panorama was madeI spun my video camera at several places and times, trying to keep it even vertically and get good views all around the 360 degrees. I wanted to paint with images, as an abstract expressionist, to get the dimension of time into the capture. Uploading the tape into Final Cut for processing on the computer, I had several spins to choose from.
When there was too much contrast between dark and light areas, such as the interior of a garage vs. the sunny driveway, the camera blurred and could not read the light and adjust to the changes fast enough. The evenly-lit landscape worked best.
When I lost my footing or was distracted, the spin was irregular and the sequence of images didn't match. A solid flat regular concrete base worked best.
At 30 frames per second, I had about 56 frames to work with. In QuickTime Pro I exported them to TIFF images. In Authoring Studio I cut out approximately 4 images between each selected frame that would have about 1/4 of the image overlap with the previous one. I ended up with 11 images to stitch.
The dog and bubbles came from another movie. In Photoshop, I superimposed them. Then remade the QuickTime panorama in Authoring Studio.
I exported the equirectangular JPEG as a web image at 100% quality. It was only about 3000 pixels long, limited by the resolution of the exported video frame sources.
