ISO, & the use thereof

I used to fiddle with ISO until I got the shutter speed I wanted to freeze action or whatever but then one day I had a light bulb moment and realised I was just wasting time fiddling with ISO since I knew the shutter speed. I thought to myself since I know the shutter speed I want then why not just lock it in directly or as a minimum shutter speed.

That's how I came to using aperture priority with a minimum shutter speed plus Auto ISO as described earlier.

I was using that technique, in genuine low light I now use manual mode, set the aperture & shutter speed, then ISO as exposure comp as I described previously. Just seems a bit more natural and intuitive to me, because I'm shooting mirrorless I can see exactly what I'm going to get, it doesn't even register that I'm using ISO, just a dial that makes the exposure brighter or darker

Ah yes. Pedant is as pedant does.

Great dumpster comeback LOL.
Ciao.

Ha ha ha ha. We were having a nice discussion, right up until the point you came along, and added...................................................nothing.

The least attention you can give to ISO is putting it into Auto mode :).

I often give less than that. Light is another matter.

My perspective on these issues is well known here, so I’m going to refrain from commenting until and unless we get to untrodden ground.

You wrote, "I always...lock in base ISO only when using a tripod"

A fine example of the degree of obfuscation offered by modern cameras. On my c.20-yr old DSLR, 'aperture priority' is just that - with the shutter going wherever the metering says it should ... up to 1/6000sec down to 15sec both of which are "the limits" - not possible to set anything in between.

At my age, simple and easy to handle - especially if the metering goes outside of plus or minus 3EV - then it refuses to take the shot

No obfuscation at all. Afaik that is predominantly how aperture priority still works in modern digital cameras.

Setting ISO and/or shutter speed limits in modern cameras is optional, not mandatory.

The obfuscation arises from the numerous options available beyond simple aperture priority, shutter priority and even "manual".

You yourself shoot in aperture priority but with a limit on shutter speed and with auto-ISO selected.

I never said they were mandatory.

I see that as a stupid statement because you are quoting just the bits that suit your agenda 😎😎

What I actually said is -

And in my post you replied to I said -

So contrary to you claiming I suggested base ISO is usable only when my camera is on a tripod with no movement in the scene, I actually stated that my camera sets base ISO where appropriate and so it is totally usable.

Perhaps read all of my posts before commenting and don't screw things up by quoting bits and pieces out of context to suit your agenda 😍😎

Logically so, but for some reason many people seem to get the opposite feeling. I don't know how many times I've read people commenting that cameras should have two modes on the dial for manual exposure times and manual apertures; one called "M", which would be full manual, and one called "I", which means "ISO priority" even though one sets exposure time and aperture, and ISO is automatic (ISO actually has the lowest priority). Of course, most cameras already have "ISO priority"; it is when you set a manual ISO in "P" mode.

With video I normally also use Auto ISO but lock in the nearest shutter speed to
1/(2 × frame rate)
