Advent Calendar – main view <\/figcaption><\/figure>\n<\/div>\n\n\n

Although I generally photograph books and flat documents, I occasionally have the opportunity to photograph three-dimensional objects. Depending on the type of object (this fold-up calendar, cuneiform tablets, a mummified crocodile!), I use different lighting setups and camera techniques. As I photograph these rare objects, I’ve become more and more interested in trying to represent them in as close to three dimensions as possible.<\/p>\n\n\n\n

In lieu of a 3-D scanner, I have been experimenting with creating 360\u02da rotating views of the objects. Done as sort of a proof-of-concept project, I photographed this Advent calendar, part of our Harris Broadsides Collection<\/a>, using 360\u02da rotating processes. <\/p>\n\n\n\n

The process is actually pretty straightforward: you set up your camera and lights (all your settings and positioning must stay the same); and your object must be stable, and centered on a surface that can be rotated in small increments (as close to every 5\u02da or every 10\u02da as possible). While you can buy these devices, we took a more DIY route and made one using a lazy susan. To ensure that I rotated each shot only 10\u02da, my coworker generated an Adobe Illustrator file that had each 10\u02da marked out exactly. While we have since started using a 5\u02da model for better accuracy and more smooth rotations, it worked quite well:<\/p>\n\n\n

The two different printouts I use when making 360\u02da images.
Left: the printout used for this setup, with markings every 10\u02da, yielding 36 shots;
Right: our newer printout with markings every 5\u02da, yielding 72 shots.<\/figcaption><\/figure>\n<\/div>\n\n\n

I then used the Illustrator printout to mark off 10\u02da on the lazy susan, centered the calendar on the surface, and began shooting. I lined up a spot on my shooting table which I could line up with each marking, and made my shots. I ended up with 36 images, and removed the background from each one.<\/p>\n\n\n\n

While we can upload the images to the web and create interactive rotation using HTML5 & JavaScript, we can also produce movies that allow for a similar viewing experience. We also hope to work with our repository team to add zoom and angle-of-view functionality. Below is a sample movie:<\/p>\n\n\n\n
