Failed panoramic photo is a lesson in itself

Who cut a white apple in the middle of my panoramic photo?

Putting in the work is no guarantee that a thing will work.

I’ve been experimenting with panoramic photos of the vertical 180 degree kind. Last night I though I might have pulled it off. I didn’t but I came close.

There are two problems I’m having. One problem is that I’m trying to get away with letting software make as many of the compositing decisions as possible.

The reason this is a problem is actually the second problem, namely that neither cameras nor computers have an actual point of view.

“Things fall apart; the centre cannot hold”

A 180 degree panoramic photo must have a point of view —  a centre — or it just won’t hold together (apologies to William B.).

The centre certainly didn’t hold in the case of last night’s failed effort to composite 79 photographs — you can see the big hole for yourself.

I took the photos while standing in the middle of the alley. The photos described the path my gaze would follow if I looked from my feet to my left, and then over head and down to my right and back to my feet.

On either side of me were wooden utility poles. They were supporting a platform of transformers directly above my head. On the underside of the platform was a suspended street light.

The computer has composited the photos so the overhead light is all the way over on the left and originally there was a big data hole on either side of one of the poles.

To make at least some sense of this failed attempt I had to horizontally rearrange the image and I deleted one of the holes which, disproportionately large though they were, represented the small spot I didn’t photograph — where I was standing.

Based on several factors it would have seemed logical to me that the overhead light would be in the centre of the image.

Unfortunately, neither the camera nor the computer software — both built according to logical rules — knows anything about logic. Certainly not my kind of logic.

Basically, the more challenging the compositing of a panoramic image is, the more manual it becomes.

So why did we invent these computers again? Click the image to enlarge it.
