I first saw this scene at the Auckland Tank Farm about a month ago. At the time, I only had my 6-year-old digital compact on me while my SLR was getting repaired and the resulting pictures were not what I wanted.
As soon as my SLR returned, I retook the photos, only to discover when I got home that the camera settings were all at their defaults. While I could have probably got the image I wanted with a RAW image, I couldn’t get what I wanted with the JPEG that had been produced.
Take 3 had completely washed out skies.
Take 4, I didn’t even bother getting out my camera as it started pouring as soon as I arrived on site.
This is the fifth attempt, and most likely the last as this area will be completely levelled in the next few weeks. Some of my photos such as this one used a graduated ND filter and I was amazed at how the sky was completely white in the photographs where the filter was omitted, and how well the sky came out when it was fitted.

There will be no "Take 6" When I passed by yesterday, the three tanks in the background had been removed.
