There are work flows and approaches to using film for weddings. The first thing to realize is you can't get the el cheapos, you have to abandon them, or offer the cheaper service. The film service must offered on the basis of results, not process, ie the prints tell the tale, not the words. The best way to tell the tale is with the prints, as computer monitors can't convey the subtle differences. After a year of pushing it, I am having a great deal of success with my alt process portrait and boudoir work. It's when friends of the first few saw the actual prints in the homes of the clients that the phone went off. You could post em on the web till the cows come home. Turns out they have to see it to get it, because that is the product, and the product is far more than an image if you are doing it correctly.
