Description

Third in a sequence of three shots from the second level at the Georgia Dome.

This is the second FRC 2009 FINALS shot to be posted.

FYI, the first pano is here www.gigapan.org/viewGigapan.php?id=21481&window_height=956&window_width=1538
This pano was done once the Einstein Matches were under way and everyone is pretty much seated.

You will notice a few frames were missed by the camera and have been filled with gray. Possible cause: I had to use a spacer between camera and the pan/tilt platform. The original spacer that supported the full length of the camera got lost on the way to ATL. A makeshift spacer of 1 inch diameter was improvised. This small support combined with flex in the pan/tilt structure likely allowed for the camera to creep in rotation w.r.t. the shutter release servo/nub as the many frames were shot. This could affect the registration between the shutter button and the nub that presses on it to trigger it. I could see some flex in the camera support platform as the servo actuated the shots. It is likely that the nub that is intended to press the shutter button may have hung on a lip that is around the shutter button in a few shots.

There are also some frames that show blurring/smear due to vertical motion.

Note that to fit the Panasonic super zoom class camera, I had to flip the camera platform over and mount the servo (to release shutter) on the other side of the platform. This places the cameara and platform C of G a bit higher than the axis of tilt rotation. When near horizontal, as the camera goes over the point of balance, the backlash in the tilt mechanism may have allowed for the sudden tilt l movement to take up the backlash and hence blurring/smear in pics on he horizon (see lower section of balcony) . This could easily have taken place as the shutter released and flexed the camera support.

Keep in mind that this beta Gigapan was intended for a point and shoot camera and I have mounted a slightly larger than intended camera on it and compromised due to using the wrong spacer.

I have another very similar shot and my try to combine the best of both images to repair the deficiencies of each.
