Say your ISO 6400 was just as noise free as ISO 100, what would your default ISO be?

would it be 6400? 100? somewhere in the middle?

Then I'd pick whatever the ISO that'll give me a shutter speed either in 1/250" or 1/125" for most shots. If I need shallow DoF, then I'll pick the lowest ISO. ISO is not as important as aperture or shutter speed. The sole purpose of ISO is to give you flexibility to choose the other two for equivalent exposure.

Every digital camera has a base ISO, use that will give you the best DR, color saturation and IQ in general, so use the base ISO.

I would turn on the ISO automatic and set the shutterspeed i need or would be happy about faster shutterspeed with larger f-numbers... no default needed.

Yes... if it would be noise-free up to 6400, ISO wouldn't matter for 99.999% of all your pictures, would it?

You could just set ISO to automatic and forget about it... then concentrate on aperture or shutter speed choices. Never have to worry about ISO again.

ISO also impacts the dynamic range, so it's about trade offs. I set:

  • Aperture for the desired DOF

  • Shutter Speed necessary for a still subject, BIF, etc.

  • ISO for the brightness, considering noise & DR

  • adjust as necessary for the optimal exposure

Cheers,
Doug

Probably around 400 or 800 for daylight. Mostly 400. 100 would still get a solid look in but 6400 would be pretty handy for dusk and indoors. A default though? I would start at 400 and see where I went from there.
You still have to take into account shutter speed and stop.

Yup, part of the plan, use as needed.

To answer your question, I'd like clean ISO 6400 for birding, providing there wasn't much of a hit in DR. However this is wishful thinking.

Cheers,
Doug

assuming DR wouldnt change either as there would be no noisy pixels replacing the good color ones, id always keep it at 6400, unless i needed a long shutter speed for things like running water.

Once you have set aperture and shutter speed, does the ISO you choose affect noise and DR?

I still shoot lower ISO since the higher ISO shooting lacks some DR and looks a bit more cooked.

I think any rational person would pick the ISO that offered the best performance of all factors considered.

It would not matter. The ISO would only be useful for determining the max and minimum light I could shoot in.
