Okay, so I've been asked to take some pictures at a friends wedding. I'm a beginner and have shot weddings before but never with such low lighting. My dilema is the lighting in the building AND reception are...VERY low...with only candles and dimmed lights. My question: What equipment is needed for this such as flashes, strobes, etc..For the formal portraits and the ceremonial portraits. I'm searching for brand names that you suggest are best. Working with a Canon 30D and 420ex. Also, just bought a Gary Fong Lightsphere but haven't had a chance to work with it. Thanks!
