Hi. I am a new member. I have been taking photos for a while now for fun, but i have never had anyone to help me out, so this place seems like a good place to get some tips! Here are a few pictures I took last night. I probably could have done a little better if i had a tripod with me, but i didn't. Any critiques or ideas are greatly appreciated! Also, I have some other pictures that I would like to add, but they have people in them. They were taken while I was traveling and it would be impossible for me to track these people down and ask their permission. Is it ethical to post my pictures without their permission? Thanks!
