I would like to start by thanking everyone for their time and effort in replying. There were many good renditions that will take me a while to analyze in detail.
@Sunhillow and @black_daveth both advised that I would have been better to choose a wider aperture so as to reduce diffraction and noise. I was in my car when I saw this scene. I parked, grabbed my camera and just used its current settings. I took four quite different shots in a little less than a minute. And then the light was gone; the sun disappeared behind the cloud bank. But even if I had more time, I probably would have chosen similar settings. I usually prioritize depth of field over absolute sharpness and I’m not overly concerned about noise because my target use is the web with an overall width of less than 1200px. But I agree that f16 was excessive, especially for the light levels in that photo.
At least a couple of the renditions – @KristijanZic, @Soupy – have chosen quite low color temperatures. While I believe this choice results in the most “accurate” color rendition in the sense that the color of the light has been effectively neutralized, that is not my preferred direction for a sunrise or sunset photo. (It is also interesting that both the camera’s auto color balance and rawtherapee’s auto color balance choose a higher, close to daylight, color temperature.) I agree with @black_daveth in this regard, that you want to consider the reality of the scene. That said, one doesn’t have to look very hard for examples of excessively high color temperatures for sunrise, sunset and fall foliage photos elsewhere on the web.
@Soupy commented on the verticality of our local hydro poles: One has to remember that this is the Ottawa Valley. Just wooden poles stuck in a hole in the ground. They were probably close to vertical when they were installed but even that is not certain. The communication tower in the background is probably vertical but you need to take the centre line as reference rather than the edge. But like the color balance, I think it is more important that it looks right than it rigorously is right.
Thanks once again for all the great renditions.
