Here we see a zig-zag path leading into the bow of the cruise ship Rhapsody of the Seas (described in earlier shots), which in turn points the way to the two AMP buildings and the elevated Circular Quay railway station. (Which was built in the 1950's, and ever since then people have been screaming "Bury it! Bury it!!!")
My original comments read "I have to admit that I had never seen the need for filters on digital cameras. However since I've started playing around with a circular polariser, I have to admit that it can sometimes make for some interesting effects such as the sky here. OK, well *I* find it interesting..."
However as I've mentioned in a past shot, lens filters of any sort (except perhaps UV filters which are as much for lens protection as anything) are less functional with the sort of mirrorless cameras that I use now (2023) than they were with standard mirrored cameras as I used then.
Another thing to note is the two AMP buildings in the background, though the shorter one is mostly hidden behind the ship's bow. The taller, fully visible one behind (the former AMP Centre, now known as Quay Quarter Tower) has been extensively rebuilt and now looks NOTHING like that. The shorter one at the front is also being refurbished in 2023, and will look quite a bit different to how it did in 2008 when the wrapping comes off later this year.
