I take (took) a lot of photos of musicians for many years, concerts, and open mics of local nj musicians.
I never used AI, just because it wasn’t good then and I’m not interested, no ideas of right or wrong.
I used the mic stand to prefocus, then my ’bob and weave’ method, if the singer moves his head back from the mic, I move my prefocused camera forward the samee distance, when a fun or characteristic smirk occurs, bang, finish the shot.
I was using Sony’s red beam of death which helped the camera focus in low light when photographing Cassandra Wilson at the Blue Note. I thought it was infrared and she couldn’t see it. After a while, she looks at me, and says "are you allowed to do that?" I reply, "yes, no flash allowed".
Oh my, I learned to pre-focus on the bottom of something the same distance I wanted, piano leg, stand-up bass. It helped when shooting the drummer behind others as well.
For definite results, I used Manual Focus combined with AEL which I got good at changing shot to shot if needed.
I've used 'spot' touchup to get rid of litter, gum on sidewalks, ..., some tools you use ( for many years) in PP is a form of AI isn't it?
