I'm not sure if there's a clear distinction that can be drawn between what's done via consciousness and what isn't, but if I were to try to draw one, I would probably include vision in the stuff that isn't. If I see a person I know, I just instantly recognize them, I don't have to run a conscious process of paying attention to their characteristics and comparing them to people I know unless they're so far away that I can't see them super well. Although if they are that far away, I can run that conscious process if needed, so it is a bit of a mixed bag. Similarly with items, I can recognize all the everyday items I see at a glance without having to pay any conscious attention to any special characteristics they might be identifiable from, but if I come across a more unusual item, I might be able to come up with a better-than-random guess of what it is if I take a closer look and think about it for a while. (I would assume it's the same way for most people, but can only speak for myself.)
Social situations, too, are not a clear-cut case, I think. I can rely on my unconscious social situation processing if I don't have the time to think through what to say, but if I do have the time, I can do a way better job doing it consciously. I think most others have a higher threshold for moving over to their conscious processing for social situations than I do, but everyone still does e.g. when they have to do a presentation or a speech, or write an important letter etc.
