Smoke Gets in Your Eyes

It's now 4.40pm and it's so dark from the bushfire smoke and storm clouds that all the outside automatic lights have come on at work. On a normal day, it wouldn't get dark enough for that to happen for another 2 hours at least. The smoke is starting to get into the air conditioning system. I've taken some photos, but they are making it seam lighter than it is. It is now pitch black outside.
