I just got married in May of last year in Plainfield. We took some outside pictures down Caton Farm Rd by the entrance to one of the subdivisions. This one had a waterfall, trees and a bench to sit on. It is past Drauden and before County Line Rd.
We also had Pilcher Park in Joliet set-up for pictures in case the weather was bad. They have a great indoor facility that resembles the outdoors.
If you are having a professional photographer do the pictures, you would need a letter from him to have them developed yourself. If that is the case, you could take them to Walmart and they could have them done in about 1 hour. After you decide on the one that you want the most, take it to Michael's. They can usually get things framed quickly.
If you are looking for a photographer that will let you keep the proofs, let me know. My father does that and is very reasonably priced.
Good luck with your pictures.
