Regarding "keep the ISO low"
That has been my mantra. I don't know exactly how I picked it up, but I have been way too reluctant to raise ISO, until recently.
I thought it would reduce noise to underexpose with low ISO and bring it back in post.
It's just something I was wrong about, and it has influenced my shooting since I learned what ISO is. I actually have to fight my way out of that mindset.
A month or two ago I stumbled on a post from
@Derrel , He posted a photo and mentioned something like "shot at high ISO in daylight", and my head exploded.
I wonder what else I'm so confidently incorrect about!
