it depend on the location too. It amazes me the amount of money people put into weddings. We did this one HUGE set up with lighting. the wedding was in a 3 acre backyard. there was a pond with a water fall, tons of trees, a stage for the band, a huge dance floor and all the seating area. what we did was for every group of trees of 3 or more we would light with century colour 2500's. individual trees we used the design 250 (PR) . the pond and waterfall was all LED lit. front truss was pars for front lighting and 4 designspots 250 for the dance floor and 6 robe 1200's on the backtruss. the cake center piece had 3 lekos, and the tent area where all the seating was was all lit with small leds. now i have never run into anything this big for a wedding again. but it just goes to show you that there is lots you can do with lighting for stuff like that. not so much for effect but to make everything pretty. even if you don't have the gear you can always subcontract if there is a budget for it.
