Location:

South Brisbane
General location: Australia, South-East Queensland

The Setup:

This is my third attempt to get a panoramic photo from this location. First two were taken during the day but stitching was almost impossible: The spans on the left-hand side of the picture are long and relatively featureless. I decided to try it at night, where dappled light is available, and this proved more successful. Shooting took two hours (bracketed long exposure plus careful recomposition for each shot). I still had to zoom in to 100% to find distinguishing features to stitch together - it came down to counting dots along the span, at times.

The camera & lens:

Camera: Canon EOS 400D DIGITAL
Lens: Canon EF-S 15-85mm f/3.5-5.6 USM IS @ 15mm
Exposure: 60" @ f/11, ISO 400 (M)

Post processing:

Hugin -

  1. Auto-find control points and vertices
  2. Manually added about 300 more control points where the algorithms did not find enough significant features. This took many hours and I got a lot more intimate with the image than I had intended!
An early iteration shows that the spans with poor control points - not matching up very well. It was quick to get to this point, but very slow to get to the finished product.

The wash-up:

I noticed 45 mins in that I had my polariser on. I like to think that I learn from these things, but it seems that I don't.

There are some stitching errors, so I've actually cropped them out. I considered going back for a re-shoot to try to exclude the railing on the right, but in the end I decided it was too much effort.
