At the end of the day, it is a free world. You can meet with anyone you want to anywhere. Unless a law enforcement officer actually saw money exchanged and has proof that the money was in exchange for sex it is of no consequence that someone has a photograph of you or your car someplace. It is one of those things where you have to understand that it is a big world out there. As long as you are not being a problem when you go someplace, no one can stop you from meeting a person.
I am very new at all this- I visited a venue and upon leaving I saw the provider I finished with on the balcony of her apartment with her phone out. I feel like she took a picture of my license plates. What do I do?
What makes you think she took a photo of your license plate? How was the session? Was it good, or bad? Maybe she was just taking a picture of your vehicle so that she knows what kind of car you drive. However, it is common practice for hobbyist to park 2-3 blocks away from a providers incall to avoid situations just like this one. I am pretty sure you have nothing to worry about, and if your sersiously losing sleep over it, then send her a friendly email about it.
Good Luck!

How would she have even known which car was yours?
Why would she take a picture ?? to bust you later after the session ? Most ladies are checking there emails or texting with other clients to setup their next appointments.. etc..
It's like walking through a crowded hotel lobby, a lot of guys. especially newbies, think that EVERYBODY in the place knows they are on their way upstairs to have sex with a prostitute. The truth of the matter of course is that not only does nobody know what you are doing there, nobody cares either.
It's the same thing here, it's just your "guilty conscience" kicking in. Ask yourself this. Why would she possibly want your license plate number, and what would she do with it if that really was what she was doing?
As for what to do, my suggestion is to pour yourself a nice cold beverage and relive the fun parts (which I hope was the whole session) of the session in your mind and relax. No one is out to get you.
Hitting the nail on the head as usual. I think the was some study done (isn't there always one! 
that came to the conclusion most people walk around thinking about their lives and that everyone else is paying attention to them. In short, most of the time the only person thinking about what you are doing is you.

...of our own movies (at least in our own heads).
The reality is that we are bit players and occasionally co-stars with a few other people.
Unless you're Brad or Angelina, I don't feel that you have much to worry about -- it's probably "newbie" jitters.
