I posted this image on another forum and said I bumped the ISO to get the faster speed (shot at 2.8 in AV).

Someone replied that if I had lowered the ISO, the people in the BG (behind the net) would have been OOF.

I replied and said ISO has nothing to do with DOF (directly), especially when shooting at max f-stop and AV mode. It would only slow the speed down, causing movement blur.

Someone else said to learn the Exposure Triangle. (I am not sure if that was directed at me or the other poster)

Am I correct or am I missing something?
