This is out in the weird zone for you photo geeks.  A hosta plant and solar garden light shot at ISO 40,000.
Some noise reduction on the original file and again on the reduce-sized photo.  |

Pretty impressive, Clive. The highest ISO my little Sony goes to is 25,600.....and I wouldn't want to go there.
I always think posts like this are helpful so thanks for sharing. What did you use for noise reduction?

Thanks Helen. In better light, photos taken at ISO 8,000 and much higher are quite clean. I just used ACR noise reduction and in the resized image used PSE...not aggressive reduction as they soften too much. Think these were posted before.   |

The first thing that came to mind on your solar light photo - "take me to your leader" those old poorly made Godzilla movies that played on Saturday afternoons!!  |

This was accidentally shot at ISO 12,800. The night before I'd been doing some testing in the house at high ISO settings with my then fairly new Canon 6D Mark II. I had forgotten to set the ISO back to normal levels. Surprisingly, with just a little work in Lightroom, I had a usable image. I plan to run it through Topaz and see if that can improve it a bit more, but I'm relatively happy with how this camera handles high ISO. I've also shot at 25,600 and gotten usable images. I'm not on my home computer right now, so I can access any of those ones. For this one, it may not be a bad thing that I forgot to change the ISO, because it was very windy and the flowers were waving across a wide arc. The high shutter (1/640) and narrow aperture (f22) were actually needed.  |

Thanks for adding this, Rick. Like the way it captured the flowers in the wind.
