Photos of the Day: Three Studies in Smoke and Noise

Since I am running late today, a bonus: three photos.

All three photos are straight from the camera: no post processing. The first is from my former (and flawed but still deeply missed) Nikon D80, Nikkor 70-300VR, 300mm, f5.6 (wide open), 1/60 sec., ISO 1600 — the very bleeding edge of usefulness with the '80.

Sometimes noise is OK, which is good, because there is a helluva lot of it here. Fortunately, newer Nikons (even the old '80) generally manifest luminescence noise, as opposed to chromatic noise. Lumi noise is characterized by pixels recording different brightnesses for the same (or similar) colors. Chroma noise is evidenced when different colors, like a red pixel in the middle of a green field, pop up. Lumi noise is less distracting, and looks more like film grain.

Not as interested in this one: the background is too busy and too light. Hmm...

Oh! This is better. Depending upon my mood, I might prefer this to the first photo; I might not. The color and brightness are better here, but sometimes the darkness is important in its own right... and I generally prefer landscape to portrait oriented photos. Who knows? Your preferences will differ, as well.
