Not monsters and not mist.
But if you choose to shoot all those small things like mushrooms, bugs, mosses from a ground level, they will look huge. Quite obvious right?
The mist is a little trick too. Any small obstacle that is very close to the camera lens while you focus on something a bit further will give that misty look. It will simply block the view, but since it is not in focus you can't really see what it is. One little grass, pine needle and small stick is usually enough to do it.
My lens will not focus on something this close (few cm away from the lens) anyway, so I just get that blur. Not something I look into on purpose, but after checking the photos, I like the effect.
And so we have a few small mushrooms I shot a while ago in the park near me. I didn't think that I would find so many different types there. All I had to do is to stop and look between the grasses and around some dead tree bits.
And there they were...
