Yeah, I figured you'd want that sign to be eligible, it was more of a suggestion anyway. As I said, DOF is entirely a matter of taste (I for instance tend to turn it off in FPS games, DOF tends to distract a lot when you have to be precise, but I love DOF in photos and videos. I know, I'm weird.), so there's no reason to use it if you don't want to, that's perfectly fine. However, you might want to keep that function in the back of your head, it might come in handy in later renders
Anyway, I'm glad I could be helpful in some way, shape or form.
And, as always, keep doing what you love and never stop improving! Cheers
