The initial response to this shot is WOW, what coloration. The vivid orange and red makes for quite a statement. The detailing of the clouds is outstanding against the fingerlike branches of the tree's silhouette. It has a forboding sense to it with the darkened areas of the clouds. The perspective is well achieved with the looming sky hovering over the single bare tree.
The composition is excellent and uses the tried and true rule of thirds, as the tree area leaves about a third of the area to the left as negative space. The panorama is stunning.
High contrast? That's a questionable subject when it comes to color photography. In my opinion, true high contrast has to be opposing colors (ie: blue and yellow, green and red) on the color wheel as the prominent features of the image. This is not to say that there can't be slight variations, but since the majority of this shot is all warm tones, it lacks that kind of polarity, although the levels of color are still a stand out. I hope you find this commentary helpful. You certainly have a talent for beautiful shots and I look forward to seeing many more in the future.
This to me has 'judgement day' written all over it. There is a really dark looming feel tothe cloud cover, particularly picked out in that colour. The exposure seems spot on too. Superb! 9.
Have never been to Australia, but want to get there one day. This shot is absolutely beautiful. Great tones in the sky and nice silhouettes in the foreground. Good focus and composition too. Can't believe all the detail you got in the sky. Nice job.
