Noisy Dam at Night

[epeeist (Colin Walls)]

On a walk to the dam, I noticed that both spillways at the dam were open. I went back in the evening, to find that they had closed one of them. Here are two exposures, one with a relatively low shutter speed and comparatively low ISO:

The second has a fast shutter speed and a ridiculously high ISO, while I reasonably happy with my first shot, I am distinctly unhappy with the second. Offered in the hope that people can do better.

puhhhh, hard one. I tried it with an B/W industrial look. Hard contrasts and the noise is part of the picture.

My play in GIMP.
A blend of three images (-1 to +1 EV) in enfuse, then local increases in contrast in the mid-range.

I was actually pleased with how DT handled this noisy image.

Hello,
A nice exercise in noise processing. Here is my version, I tried to give warm tones to the light.

Yes, I tried that, and it does seem to give a better result.

I am resigned to the fact that one can’t capture the movement of the water with so much noise caused by the use of a very high ISO.
