Been playing with panoramic photography in the digital age.
If you've seen old B&W pictures that are much wider than they are tall, those were taken with mechanical film cameras that turned on a pivot and advanced the film strip as it was exposed. Cameras that would do panoramas were expensive and very complex. Now we do panoramas by stitching together several images taken by a plain digital camera and processed by software. I finished a panoramic bracket and rotator and tried a wide angle of the east wall of my machine shop. Pic is made up of 21 separate shots. Seven from side to side and three passes vertically.

The software I used to stitch the pics together is a free Microsoft program -- Microsoft ICE. Very simple to use, just launch the program and darg and drop a sequence of images and the program figures out how to stitch them together in a mostly seamless manner.

Here is another link to the build of the nodal bracket and rotator that I used to take the individual pics. http://www.boysungrain.com/panorama.htm
Now that I'm done playing, maybe a little clean up of the playroom is in order?
