I need major help. I am shooting my first wedding ever next month and need to know what equipment you would recommend. I know I need to buy a lens and a flash and am willing to spend the money to get those. The wedding is at 3:00 in a small chapel. Followed by a trolley ride of downtown Nashville. The reception will be in a dimly lit bar (Roberts Western World) from 6:00 - 9:00. They do not want me to bring a light in. I need to get a flash for my camera so I can bounce it off the ceiling, right? What lighting do I use during the ceremony? Do I use a flash? Here is what I own: Canon Rebel XSI Canon Kit Lens 18-55 0.25m/0.8ft Canon 50 mm 1:1.4 Do I need one of those big long canon grey and black lenses? What flash do I need? Any tips you can give me are appreciated. Thanks!
