So, very, sensitive.

Why go above 800? I get it, the beloved triangle, varied as it is. DOF? SS? 1600, okay, but going into noise? However, todays dslr, mirrorless, etc... we can reach upwards of 234,000 upon our sensors. I am really curious as to how many uhh'ers go high in their iso count, and for what reason.

This is a peaceful question please

Shooting in low light levels where long exposures cannot be used, eg; classical music concerts.

My next camera will probably be a Pentax KP. Like several other new cameras, it shows virtually no noise at ISO levels like 8000, which allow user to choose shutter speed to stop motion and aperture to provide desired DOF even when light levels are low.

In addition to what Richard and Ralph said, low light situations where a flash can not be used or when I do not want to use a flash.

Or when you want more range with your flash, especially if you are bouncing in a large room.

Yes, I enjoy going out early in the morning, and night shooting, so I often go to the higher ISOs

Good point.

Umm duhhh, because I have to?!?!
You say you understand the triangle, maybe you don’t understand photography?!
If I’m wide open, my subject needs 1/4000th to prevent motion blur, the sun has just gone down and NASCAR refuses to run these races in the morning....., what do YOU speculate my ISO might need to be???
Now see, that was VERY peaceful!!!!
SS

Here is a sample of mine, using a higher ISO

Flag at Washington Monument - Washington DC

No additional lighting, just used what was at the Monument

Pentax K3ii

You can say that for any ISO setting, as to why you would choose, if you need an answer...re-learn photography.

Another reason is, because we can. State of the art digital cameras can go to much higher ISOs without objectionable noise than we could get away with back in the days of grainy push-processed film.

With my Canon 7D Mark II I often go comfortably to ISO 6400 and rarely, but sometimes to 12800. These are strictly in low-light situations especially where I need to keep my shutter speed reasonably high.

A couple of aspects of modern DSLRs come into play. Does your lens provide IS / VR / in-camera stability that lowers the threshold of 1/focal-length for effective hand-holding? For your specific camera, where is the high-ISO threshold for your individual tastes in noise? Where is the high-ISO threshold for your camera and tools to process-away noise without losing too much detail? For the subject, what is the light-level and subject movement given your camera, lens and subsequent processing tools? Here's something at ISO-5000, F/2.8, 1/80, zoomed to 130mm.

I don't like to shoot too high an ISO, but will when the circumstances require it. I have shot at ISO-16000 on several occasions and 25000 in emergencies. Ya gotta do what ya gotta do.

Shooting RAW does aid in reducing noise.
