The folks at Candy Glass Productions have posted a cool tutorial on how to spin a camera around a building, using the CN Tower in Toronto as an example. This would be an awesome technique to highlight a landmark from a vacation if you're throwing together a video for friends and family. You could also scale down this technique for use on a portrait subject for any mixed media projects.
This effect isn't a new idea, but Candy Glass does a great job of mapping out the steps so you can achieve a very clean, believable result. Has anyone ever tried anything like this?
