Unfortunately I didn't accomplish what I wanted to do at the airshow yesterday. I went early to see other stuff, and I started feeling the effects of the sun and heat about an hour before the airshow. That happens to me occasionally, and I knew I had to leave. However, as I was leaving, I took some ISO 2000 shots of a few items that were plain colored.
After I got home, I remembered an airshow I did with the 1DX2 last August. It was the first airshow I had done in several years, and I did mess up some settings (I was shooting at f/25). I thought that might have resulted in high ISO. It did, and the second set of photos below does emulate what fordmondeo saw at the Loop.
This is the full photo at ISO 2000:
Here is a 100% crop with noise reduction and sharpening turned off. There is some noise in the shadows, but not much.
And this is the 100% crop with mild NR and sharpening.
From the airshow last August, this is the full photo:
This is the 100% crop with NR and sharpening turned off. The amount of noise compared to the truck is amazing. Something more than just ISO 2000 is happening, but I don't know what it is.
However, the noise cleaned up nicely in Lightroom:
My airshow settings (thanks to a friend who has shot airshows for years) use shutter priority mode with auto-ISO. I shoot helicopters at 1/40, propeller airplanes at 1/160, and jets at 1/2000. The camera takes care of aperture and ISO. I generally use spot metering. I use servo focusing, and I use the center 9 focus points. I don't have a favorite "case" in the servo settings. I've tried 1, 2, and 4, and I don't see any difference in my yield. I use high speed shooting at the full 14 fps.
This post shows some airplanes that were shot with the above settings.http://photography-on-the.net ...showthread.php?p=18355441
