I probably should have worded it differently, but thanks for calling me an idiot. Jeez. I guess my point was, does a faux even know WHAT these things are and how they relate. Yes, ISO and f-stops are related, of course, depending on what lens you use, yes. I’d shoot at 100 ISO anytime when possible, to minimize noise. But if the lens I have available doesn’t go down to a 1.8 and the lighting is a bit dim, the ISO has to go up unless I want to compromise shutter speed. Favorite F-stop also, I prefer to shoot wide open (situation permitting). I have a go-to lens that is versatile for many situations but also have others that I will use of course. RAW conversion- I meant do you prefer Camera Raw or Lightroom. I use Lightroom to import and then do editing both there and in Photoshop, then my batch export from LR.
