Ian - You are absolutely correct. These images that were taken with by 1965 (!) Nikon FE was before my Usefilm days, and definitely before I started consiously using the rule of thirds to add some dynamics to the photographs.
I'm glad you have looked and compared the photographs - I wanted to load a series of three images to show different interpretations of the same subject. All were taken over 30 minutes as the sun set.
Hi Michael, redundant to say, this is the image I referred to in my previous comment. The point of attention (at least for me) is more focused on the sky, and the left part in particular. Again, a small crop (this time on the right hand side of the image) to remove the centered element, but that's less important in this photo. Good job.
