Old ventilation stacks lit by flashes of alternating green and orange light.


Seven Hills TAFE, Brisbane
General location: Australia, South-East Queensland

The Setup:

On the roof of this building, these seem to be ventilation / air conditioning stacks. For this shot, I controlled the cameras while Alan walked between each stack and fired off alternating green and orange flashes.

In Alan's version of this shot, he also fired off two shots to light up the front of the nearest stacks. This actually gave quite a different feel to the shot.

The camera & lens:

Camera: Canon EOS 650D
Lens: Canon EF-S 15-85mm f/3.5-5.6 USM IS @ 18mm
Exposure: 106" @ f/6.3, ISO 400 (M, bulb mode with intervalometer)

Post processing:

Lightroom 4 -

  1. Presence: Shadows +85, white clipping +50, black clipping -40, clarity +10
  2. Curves: Darks +20, Shadows +15 (I used curves to bring out the shadows at the front, as it is a more subtle effect).
  3. Noise reduction: luminance +25, colour +100
  4. ACR lens correction profile for EF-S 15-85mm.
  5. Careful crop and rotate so everything was centred and balanced
  6. Graduated filter in the sky area: exposure -1 stop (to darken the sky; this was facing towards the city and the sky was quite bright)

    That really does give the shot a different vibe, more mysterious “what’s lurking behind” kind of deal. There’s that dreadful snapshot of me, too…yoiks! xD
