Hi, I'm somewhat new to photography as a serious hobby. I've been taking pictures for roughly a year.. and I'd like to get a bit more creative. I'm aware that distortion is usually unwanted but I frequent parties and whatnot and feel that lens effects would be great for capturing the feeling. http://sphotos.ak.fbcdn.net/hphotos..._416489412961_504522961_4448921_7223566_n.jpg and http://sphotos.ak.fbcdn.net/hphotos..._404678812961_504522961_4158166_4076431_n.jpg are examples how would i get this effect on a budget? say 200 dollar max and used is more than alright. i'm not opposed to filters if they'll get it done! thanks guys. i used the search before hand but didn't see anything. I have 18-55mm lens and a 50mm prime both with 52mm thread? is that what it's called?
