Thanks guys. Adrian I understand your second example. For the first example, are you saying that it's sort of a way of breaking down a stop into smaller pieces? So its half way between 2.8 and 4? Remind me to go memorize the f stop scale. My mom would never want me to say this but im a minor (out of respect for her I'm not gonna say my actual age, though I trust you guys) who does event camera work but I love doing fiction stuff and my goal is to be DP so let's see how this turns out. Thanks again guys.
