@ 204,800 iso.

Limited out in the dark (at 320/s) The D4 cranked it to the max on this bear, straight from camera, my first time hitting those numbers so I thought I'd share

When forced to use high ISO and if the scene allows it, try over-exposing the subject by a stop to greatly reduce the noise level. Just don't go so far that you lose highlights that you want to keep. I expect you might have lost little detail in the stones and tree trunk but gained a lot on the bear so long as it was not moving too fast and in the vegetation.

How did you take this photo ? I would have used M exposure mode to set the shutter speed I needed for the action and camera motion and set the aperture I needed for DOF and let auto-ISO take care of the exposure (along with any exposure compensation that I dialed in). The only problem is that with this approach I cannot use exposure bracketing without the camera changing the aperture or the shutter speed. Nikon almost got it right.

ISO 204,800.....not much room for overexposing

It was the last shot as he/she went bush. I wasn't taking the image to keep, I knew the iso was up there.

My settings were A mode with -.7 exp comp matrix. In the auto iso settings my min shutter was @ 320/s.

I lowered my min shutter from 500/s a little earlier as it was getting pretty dark quick.

If you have room to over-expose you don't need to use such high-iso to begin with

What was the aperture used? I 'm trying to imagine how dark it was.

F4 I believe, was at 5.6. I could have slowed the shutter down to lower the iso but last time I was at 200/s with the 300 F4 the images weren't as sharp as I hoped.

I was just shooting while I waited for my mother to finish, I knew the images weren't usable, she was shooting at much lower shutter speeds, but I can guarantee they'll be blurry , but yeah, I wish I had a flash light walking out of the woods :P It wasn't hugely dark right then though. But 320/s + F4 = high iso.

I thought - exp comp would lower the iso, he is already overexposed slightly imo

another one, I like that you still get detail & the grain works in B&W.

This was at 1/250 - F4 - 204,800 iso

Regardless of whether alternative setting may have given a better result or not… ISO 204,800… WTF!!! How far we have come.
