You can get some great expressions from people when they make eye contact with you. Most of the time I dismiss the photos, as it's not what I’m looking for at that moment and other times it will make a great photo.
I normally try to avoid eye contact, why you might ask. Well for me it can change or disturb the moment.
Now there are some cases where I’ll wait until the person notices me and then you get a wonderful expression a laugh, shock or anger.
I’ve added some photos that show the moments when eye contact is made.
Enjoy
