Title: Can someone take a photo of you without consent?
Question:Edit: Forgot to add that this is in Colorado, United States 

Me and my boyfriend were cruising in our truck and happened upon a field where clearly vehicles had been going mudding since there was a full on "race track" going around it. We didn't see any signs saying private property or no trespassing so we decided we'd have a little fun then go on our way. Well low and behold after one lap a car comes out of a nearby mobile home park and waves us down. We drive out the field and pull up beside the car that had flagged us down to see what was up. As soon as we pulled up the man in the car started taking photos of us (in our truck) without saying anything beforehand. A bit freaked out and startled we both covered our faces as fast as we could and started trying to get the guys attention with "hey hey hey" and "whats going on?" he tells us it's private property and someone broke into his shed and stole things a few days ago. We politely explain our situation and that we were just cruising and would be on our way. This guy still had an attitude as he said "Well the cops are gonna find whoever's doing it and I'll call them if i see you again" 

I completely understand not being allowed on his private land but is he allowed to just start taking photos of us and threatening to call the cops without even explaining why and when there were no signs saying no trespassing or private property? 

Edit #2: Okay thanks to the people who let me know in a polite way that I have a lot less privacy than I initially thought. I had no clue someone could take a photo of (specifically not just a photo with other things in it) me in my own vehicle or infront of my own house. Thought that stuff would begin to cross into stalking territory. Again, thank you to the people who did let me know in a polite manner.

Answer #1: Yes someone can take pictures of you trespassing or on any public or private property where you have no expectations of privacy. Answer #2: You do realize that you're photographed basically every time you leave your house, right? Ever use an ATM? Ever been in a store? Ever seen a news broadcast where they are videotaping everyone who walks by?
