Max ISO
Mar 3, 2021 15:21:15 #
I have a D7500 and I was wanting to get some thoughts / insight into max ISO. I have mine set to 6400 for just normal every day pics. For this camera do you think that is as far as it should be pushed to not run into noise.

The only way to find that out is to try it yourself... Noise is so subjective and more dependent on exposure than ISO...

Just one question... Why so high a ISO?

Any cameras I know would have visible noise at ISO 6400 with current technology. So I wouldn't use ISO 6400 unless it's needed.

There is nothing better than natural light. When we use artificial lights we're only trying to simulate natural light. The newest DLSR's do very well at high ISO's so you can take advantage of the existing ambient light. Not all noise s so objectionable. Do some experimenting as there is no expense involved. Sometimes a little noise is better than not getting any shot, or washing it out with a directional flash.

Well I guess that was my question I was somewhat experimenting with it trying to decide if it was too high.

Get the shot. Use whatever it takes to get the shot. Set MAX ISO as high as it will go. If you need it get the shot!

Test it yourself.
The general best practice is to use as low an ISO as possible. Typically, you'll try to remain at the 'base ISO' for a camera model, typically ISO-100. Of course, shooting only in bright light using ISO-100 is rather limiting.
But, defaulting to the highest and noisyest setting for a camera is probably an even less optimal approach. You'll end up with rather small apertures (causing lens diffraction) and super fast shutter speeds, maybe faster than the camera can support.
Your own testing and verification of the resulting images will give the best details to consider.

IF ISO, Shutter speed and aperture number are three sides of a triangle, isn't you question akin to "Why so high a shutter speed?" or "Why such a small aperture?
I would propose the answer to all three would be: "Well, because."
Shutter speed controls motion
Aperture controls Depth of Field
ISO controls feel

I've spoken to Canon about my 77D and they said they feel comfortable up to 800 iso but keep it lower if possible. It also depends what your doing with photos, amount of enlargement and tolerance for noise

Noise can be filtered, if you have something to work. Get the photo at all cost.
I regularly use a 1" sensor compact. With a much smaller sensor I get more noise. That camera's highest ISO is 12800. I will use it without a second thought if I need it to get the photo.
Here's an image shot at ISO 12800 with that 1" sensor. The noise has been filtered using DXO PL4. Is that too much noise? There's some detail loss from the noise filtering and personally I wouldn't lean on it that hard as I don't mind a little noise.
